Whether all sunlight is absorbed by chloroplasts

Sunlight is composed of red, orange, yellow, green, blue, indigo, purple and other seven colors mixed, in the process of plant photosynthesis, plant chloroplasts absorb red light and blue-violet light the most, so red light and blue-violet light are the most suitable light quality for plant photosynthesis. Different light quality also affects the photosynthetic rate of plants. Phaseolus vulgaris had the fastest photosynthetic rate under orange and red light, followed by blue and violet light, and green light was the worst.

Other higher plants and green algae have similar results. In general, the photosynthetic peak under the influence of different light waves is equivalent to the peak of the absorption spectrum of chlorophyll and carotenoids. The water layer also changes the light intensity and quality.

The deeper the water layer, the weaker the light, for example, comparing the light intensity at a depth of 20m to the light intensity on the water surface. The former is one-twentieth of the latter, and the water color is not clear and the light is weaker. The absorption of the red and orange parts of the light wave is significantly greater than that of the blue and green parts of the water layer, and the light in the deep underwater layer is relatively rich in short-wavelength light.

Therefore, green algae containing chlorophyll and absorbing more red light are distributed on the surface of seawater, and red algae containing phycoerythrin and absorbing more green and blue light are distributed in the deep layers of seawater. This is the adaptation of the seaweed to light.

Of course not, the chlorophyll in chloroplasts absorbs more red-orange and blue-violet light and less green light.

No, chloroplasts absorb light differently to different colors!

No, only part of it is absorbed by chloroplasts.

No, green doesn't absorb it, so it looks like the leaves are green.

<> part of chloroplasts that absorbs light energy is pigment. The pigments in chloroplasts have the role of absorbing, transmitting, and converting light energy, and these pigments are distributed on thylakoid films. Chloroplasts are a type of plastid and are energy converters unique to higher plant infiltrates and some algae.

Its double-layer membrane structure separates it from the cytoplasm, and there is a lamellar membrane inside, which contains leaves and shouts hand-spindleburn, so it is called chloroplast. Each lamellae is made up of two membranes that are closed around and are in the shape of a flat sac, called thylakoids. Within the thylakoids is an aqueous solution.

Small thylakoids are stacked on top of each other to form a basal granule, and such thylakoids are called basal saccharoids. The sheets that make up the basal grains are called basal lamellae. Large thylakoids traverse the stroma and run between two or more basal granules.

Such a lamella is called a stromal lamellae, and such a thylakoid is called a stromal thylakoid.

Plastids are formed from proplastids. Protoplasts are also precursors to other plastids and are generally colorless. Protoplasts are found in meristem cells at the apical apex of the stem with a double membrane and a small number of vesicles inside.

When the leaf primordium differentiates, the inner membrane of the protoplast folds inward and extends out of the membrane layer system, and under the light luck Hu Sheng, these sheet systems continue to develop, and chlorophyll is synthesized, which develops into chloroplasts. If the plant is placed in the dark, some tubular membrane structures will be formed inside the plastid, which can synthesize chlorophyll and become yellowed plastids. If these yellowed plants are illuminated, chlorophyll can be synthesized, the leaf color turns green, the lamellar system is fully developed, and the yellowed plastid is transformed into chloroplasts.

Therefore, not only the formation of chlorophyll requires light, but also the formation of chloroplasts.

Required, mainly for the production of chlorophyll by photosynthesis.

"Plant World", the most popular, fashionable and novel science popularization book for teenagers.

Many organisms do not have chloroplasts, but they can naturally photosynthesize because photosynthesis can take place as long as there are enzymes and other conditions necessary for photosynthesis. The premise of the above statement is that the plant is the premise. This question is a bit of a bull's errand.

"The main premises.

The statement is incorrect. Chloroplasts are the site of photosynthesis. Because there are only two phases of photosynthesis, both the light reaction and the dark reaction are in the chloroplast (the light reaction is on the thylakoid membrane, while the dark reaction is in the chloroplast inner membrane).

This question depends on the constraints in the title, if it is mesophyll cells or something, chloroplasts are the only place of photosynthesis, and the main word is wrong. If it is for all organisms, the main should be added, because there are also prokaryotes, such as cyanobacteria, which do not have chloroplasts, and rely on photosynthetic pigments and enzymes for photosynthesis.

It's the main venue, right.

For example, cyanobacteria are prokaryotes that are chloroplast-free, but they contain phycocyanin, which can also carry out photosynthesis.

The site of photosynthesis of green plants is chloroplasts, remove the main.

Photosynthesis is mainly done by enzymes, and chloroplasts can be completed because they contain enzymes necessary for photosynthesis, so even if there are no chloroplasts and there are enzymes necessary for photosynthesis, light and action can be carried out, and it can be explained with high school knowledge.

When you go to university, you will learn that photosynthesis is divided into two parts: dark reaction and light reaction, but the light reaction on the membrane and the dark reaction in the matrix.

So the main site of photosynthesis is chloroplasts, and the substrate also has a part of photosynthesis.

Yes, the main venue. Higher plants photosynthesize in chloroplasts. However, some lower plants and microorganisms do not have complete chloroplasts, such as cyanobacteria, which can also carry out photosynthesis, but do not have chloroplasts.

The questioner may have been a high school student, and some of the questions said that "chlorophyll is the main site of photosynthesis" is wrong, because chlorophyll is only involved in a part of the photosynthesis light reaction. But there is nothing wrong with "chloroplasts are the main site of photosynthesis", light reacts on the chloroplast membrane and dark within the substrate. So I think there's something wrong with this topic.

I majored in biology in college, and I also participated in exam tutoring in high school biology, so welcome to discuss.

This sentence is wrong in the main two words, the place of photosynthesis is only chloroplasts, and the main place of respiration is mitochondria, so it is correct.

The energy converters in plant cells are chloroplasts and mitochondria Chloroplasts are the places where photosynthesis is used to make organic matter, and the chlorophyll in chloroplasts can absorb light energy, convert light energy into chemical energy, and store it in the organic matter it produces; Mitochondria are the site of respiration, which can decompose the organic matter in the cell into carbon dioxide and water under the participation of oxygen, and at the same time release the chemical energy in the organic matter, which is as high as the utilization of the cell, so the stem statement is correct

So the answer is:

No, in chloroplasts, most of the chlorophyll a, chlorophyll b, carotene and lutein can absorb and transmit light energy; Only a small fraction of chlorophyll a converts light energy into electricity.

Mistake. There are pigments in chloroplasts: carotene, lutein, chlorophyll a and b, all of which can absorb light energy (but only some of chlorophyll a can convert light energy).

Wrong. The pigments on the cystic structure films in chloroplasts can be divided into two categories: one is the one that absorbs and internally transmits light energy.

capacity, including most of the chlorophyll a, and all of the chlorophyll b, carotene and lutein;

The other type is a small number of chlorophyll a in a special state, which can not only absorb light energy, but also convert light energy into electricity.

Therefore, it is not only chlorophyll that can absorb light energy in chloroplasts, but only part of the excited chlorophyll a. can convert light energy into electrical energy

Chlorophyll is found inside plant cells, where it absorbs a portion of the color light to boost energy.
