Find the concept of photosynthesis in plants. Can all plants photosynthesize

The so-called photosynthesis is the process of green plants using light energy to convert carbon dioxide and water into organic matter Photosynthesis can be roughly divided into light reaction stage and dark reaction stage Photolysis of water is carried out in the light reaction stage, and carbon dioxide fixation is carried out in the dark reaction stage Light reaction and dark reaction are a unified whole, and both are indispensable, otherwise plants cannot grow normally

It's already detailed and doesn't need to be added.

Not all plants are capable of photosynthesis.

Chloroplasts are the basic conditions for plants to photosynthesize, so no plant without chloroplasts can photosynthesize.

Mononuclear algae such as cyanobacteria and globular algae, as well as parasitic plants such as gastrodia and silk seeds of the orchid family.

Cuscuta chinensis lam), also known as Zen Zhen, Bean Parasitism, Bean Yama King, Yellow Silk, Yellow Silk Vine, Golden Silk Vine, etc.

Annual parasitic herb. The stems are winding, yellow, slender, leafless. The inflorescences are lateral, with few or many clusters of flowers forming small umbels or small clusters of umbels; bracts and bracts small, scaly; peduncle slightly stout; calyx cup-shaped, commissurated below the middle, lobes triangular; corolla white, pot-shaped; stamens bearing corolla lobes bent slightly below; scales oblong; The ovary is nearly spherical, columella 2.

The capsule is spherical in shape, almost entirely surrounded by a corolla. Seeds 2-49, light brown, ovate, about 1 mm long, with a rough surface.

The Flower of the Underworld "has no leaves or flowers, and instead has white scales all over the plant, which usually clings to dead creatures to draw nutrients, which is where it comes from."

Plants that don't need to photosynthesize, but are covered in scales and are called "flowers of the underworld" (what are some plants that can't photosynthesize?). -Zhihu (

Plants that do not photosynthesize can survive as long as they can get enough energy. It is mainly divided into two categories: parasitic plant rights and saprophytic plants.

Strictly speaking, parasitic plants still have a lot of photosynthesis. For example, mistletoe and mulberry parasitism all have leaves, of course, the most cattle's parasitic plants should be heavy parasitic plants, these guys are parasitic on the parasitic plant mulberry parasitism. These plants are almost reduced to the point of having only inflorescences, they live entirely on the host, and all the nutrients are drawn from the host's vascular bundles.

Photosynthesis is certainly not required.

There are many orchids that are saprophytic and live like mushrooms. For example, we are familiar with gastrodia. As well, some coral orchids and mesa orchids.

These plants rely on symbiotic fungi that break down cellulose in decaying plants for nutrients. These plants also do not need to photosynthesize.

Not all plants can photosynthesize, for example, Cuscuta is a parasitic plant and cannot photosynthesize.

Plants with green leaves are able to photosynthesize. Nutrients are made through photosynthesis.

Not all plants are capable of photosynthesis. Not all plants can photosynthesize, they must contain enough chloroplasts for photosynthesis. In the deep sea or some plants that do not have chloroplasts are not able to photosynthesize.

The process of photosynthesis is a relatively complex problem, on the surface, the total reaction formula of photosynthesis seems to be a simple redox process, but in essence it includes a series of photochemical steps and material transformation problems.

Reaction process:The process by which green plants use the sun's light energy to assimilate carbon dioxide (CO2) and water (H2O) to make organic matter and release oxygen is called photosynthesis. The organic matter produced by photosynthesis is mainly carbohydrates and releases energy.

Plants need light for photosynthesis.

Plants use the energy of light to convert carbon dioxide and water into sugar, but plants only accept light in the range of 380nm-780nm, which is called PAR. If the plant is shaded, photosynthesis will continue but not reach the optimal state, the plant can not maximize the production of sugar, usually in agricultural production activities, we need to maintain healthy plants and fruits with the sweetness standard under the premise of ensuring light intensity, such as Xinjiang because of the long sunshine time, so cantaloupe will be sweeter.

Photosynthesis: It is the synthesis of light energy, which is a biochemical process in which plants, algae and some bacteria, under visible irradiation, through light reaction and dark reaction, use photosynthetic pigments to convert carbon dioxide and water into organic matter, convert light energy into chemical energy and store it in organic matter, and release oxygen removal.

Photosynthesis

Photosynthesis is the process by which green plants (including algae) absorb light energy, synthesize carbon dioxide and water into energetic organic matter, and release oxygen at the same time, under the conditions of photopigment molecular enzymes, carbon dioxide (or hydrogen sulfide).

Photosynthesis mainly includes two stages: light reaction and dark reaction, which is of great significance for realizing the energy conversion in nature and maintaining the carbon and oxygen balance of the atmosphere.

The most important products of photosynthesis are carbohydrates, which include monosaccharides, disaccharides and polysaccharides. The most prevalent monosaccharides are glucose and fructose; Disaccharides are sucrose; Polysaccharides are starches. In the leaves, glucose is often converted into starch and stored temporarily.

However, some plants such as onions, garlic and other leaves do not form starch in photosynthesis, only sugars.

In addition to carbohydrates, the products of photosynthesis include lipids, organic acids, amino acids and proteins. The quality and quantity of various photosynthetic products were different under different conditions, for example, more nitrogen fertilizer and more protein formation, less nitrogen fertilizer, more sugar formation and less protein formation; When plants are young, protein is formed more in the leaves, and with age, the formation of sugar increases. Different light waves, such as blue-violet light, synthesize more protein, and wheat in mountainous areas has high protein content and good texture, while more carbohydrates are synthesized under red light.

Plant photosynthesis is a biochemical process that is the basis for the survival of the biological world. Plant photosynthesis refers to the biochemical process in which plants absorb light energy, convert carbon dioxide or hydrogen sulfide and water into organic matter, and release oxygen or hydrogen. Plant photosynthesis is also known as photosynthesis.

Introduction to photosynthesis.

Photosynthesis is divided into two stages: light reaction and dark reaction, and the organic matter produced by photosynthesis is mainly carbohydrates and releases energy. Photosynthesis of plants occurs in chloroplasts and photosynthetic bacteria of green plants, involving important reaction steps such as light absorption, electron transfer, photosynthetic phosphorylation, and carbon assimilation, which helps to regulate the atmospheric carbon-oxygen balance, and is of great significance for realizing the energy conversion in nature and maintaining the atmospheric carbon-oxygen balance.

While assimilating inorganic carbides, plants convert solar energy into chemical energy, which is stored in the organic compounds formed. The solar energy assimilated by photosynthesis is about 10 times the amount of energy required by humans every year. The chemical energy stored in organic matter, in addition to the use of the plant itself and all heterotrophs, is more important for the energy of human nutrition and activity**.

Biology knowledge for junior high school: A short animated film will take you to understand the principle of photosynthesis in plants.

The product of photosynthesis in plants is organic matter, which is used to store energy and oxygen.

There is oxygen after the consumption of carbon dioxide.

Products of photosynthesis The carbohydrates made by photosynthesis are first of all glucose, but glucose soon turns into starch, which is temporarily stored in chloroplasts and later transported to various parts of the plant body.

Under the exposure of sunlight, green plants absorb carbon dioxide and water from the outside world, and use light energy to produce organic matter mainly carbohydrates and release oxygen in chloroplasts. At the same time, light energy is converted into chemical energy and stored in the organic matter produced. This process is called photosynthesis.

The reaction formula of photosynthesis can be expressed by the following formula: 6CO2+6H2O=C6H12O6+6O2

The organic matter produced by photosynthesis, except for a part used to build the plant body and respiration consumption, is mostly transported to the storage organs of the plant body for storage, and the food and vegetables we eat are these stored organic matter. Therefore, the products of photosynthesis are not only necessary for the life activities of plants themselves, but also directly or indirectly serve other organisms (including humans) and are used by these organisms. The oxygen produced by photosynthesis is also one of the most abundant oxygen in the atmosphere.

There are three: 1. Reducing hydrogen 2, oxygen 3, glucose chemical reaction 6CO2 + 6H2O = C6H12O6 + 6O2

Oxygen products, of course, are oxygen.

Photosynthesis is the process by which green plants, including algae, absorb light energy and use carbon dioxide and water to synthesize complex energetic organic matter, while releasing oxygen.

The organic matter produced by photosynthesis is mainly carbohydrates.

The total equation for photosynthesis:

6Co +6Ho (light, chloroplast) C H O[(CHO)]6O2

1. Plant photosynthesis (photosynthesis), that is, photoenergy synthesis, is a biochemical process in which plants, algae and some bacteria, under the irradiation of visible light, undergo light reaction and dark reaction, use photosynthetic pigments to convert carbon dioxide (or hydrogen sulfide) and water into organic matter, and release oxygen (or hydrogen). Photosynthesis is the sum of a series of complex reactions, which is the basis for the survival of the biological world and an important medium of the earth's carbon and oxygen cycle. Photosynthesis) is the use of photosynthetic pigments such as chlorophyll by green plants and the use of their cells by certain bacteria such as halophilic archaea with purple membranes.

2. The biochemical process of converting carbon dioxide and water (hydrogen sulfide and water for bacteria) into organic matter and releasing oxygen (hydrogen released by bacteria) under the irradiation of visible light. Plants are called producers of the food chain because of their ability to produce organic matter from inorganic matter and store energy through photosynthesis. Through consumption, consumers in the food chain can absorb the energy stored by plants and bacteria with an efficiency of about 10% to 20%.

For almost all living beings in the biological world, this process is the key to their survival. And in the carbon-oxygen cycle on Earth, photosynthesis (which keeps oxygen and carbon dioxide levels relatively stable) is essential.

The essence is the synthesis of organic matter, which stores energy. Photosynthesis is essentially an energy conversion process in which green plants (including algae) absorb light energy, synthesize carbon dioxide and water into energetic organic matter, and release oxygen at the same time.
