Plants, like animals, can change the world

Of course, plants absorb carbon dioxide from the air, reduce the greenhouse effect, and purify the air

Plants absorb carbon dioxide from the air, release oxygen, and reduce the greenhouse effect.

A leaf is an organ of vascular plants that grows from a stem and its function is to make nutrients for the plant. The leaves are mostly flattened and grow on slender petioles. Yes.

The lower epidermis, in the middle of the epidermis is the mesophyll of the chlorophyll tissue, and the veins pass through the mesophyll, which are the extension of the vascular bundles of the stem. Some leaves grow many detached leaflets, each with its own short petioles. The leaves that have leaflets are called compound leaves.

What is not is a single leaf. Usually there will also be a pair of green at the base of the leaf. Flattened leaves allow for photosynthesis, but not all leaves have leaves.

Many monocots, such as grasses, do not have petioles at the leaf base but have leaf sheaths that surround the leaf stems. The leaf life span is very short, although the leaves of conifers and broad-leaved evergreens can live for 2 to 3 years, after a year the contribution of these old leaves is already small.

Photosynthesis. Plants can make food just by being exposed to sunlight, that is, by photosynthesis to make nutrients. Plants synthesize glucose, a monosaccharide, from water and carbon dioxide when exposed to sunlight.

Plants provide glucose to their own cells as fuel and make other substances such as starch and vitamins.

evolved.

In the beginning, it originated in the ocean, and it was only a single-celled organism, and then some microorganisms that could produce oxygen appeared, which gradually changed the composition of the atmosphere, and the landscape was gradually changing, and the sea water receded, and the land was exposed. Then some of the creatures remained in the sea (water), which is today's fish, and then some of them came ashore, which are today's animals. And then there are some people who run around in the trees every day, gliding and so on, and gradually becoming birds.

It's all the result of evolution. It's a lot more complicated than I said. It's so complicated that we can't imagine it.

As for why some fish go ashore, I think the main reason should be competitive pressure, because at that time, the competitive pressure in the water will be very large, there will be many races are at a disadvantage, at this time they must find a way to live, and then gradually go to the shallow water to live, and then gradually go ashore, and then gradually completely out of the water body, and then gradually adapt to the land environment, and lose the characteristics of fish, and then gradually evolve a variety of animals.

Plants can produce sugars that are consumed by animals.

Plants can produce protein, and there are questions to ask about it.

Answer: Plants produce oxygen and absorb carbon dioxide, balancing the cycle of oxygen and carbon dioxide in nature, and the ozone formed by oxygen can also resist high-energy rays in the atmosphere, further protecting the earth's flora and fauna.

Plants are decomposed by bacteria after they die, thus forming soil, plants absorb dust, shelter storms, and without plants the earth is full of storms.

The question I asked was that Qing gave me ten reasons why there are plants in the world.

Hurry, hurry, hurry.

Ask ten questions, you're sure.

Question: What are the ancient units of measurement?

Stone, Jun. In ancient times, the common units of length were: 跬, 仞, she, and xun.

Stone: An ancient unit of capacity or weight. Ten buckets are one stone, and one hundred and twenty catties are one stone.

Beans: A unit of capacity. Hu:

Capacity unit, five buckets for one.; Jun: a unit of weight, thirty catties is one jun; Foot:

The unit of length, half a step for the foot. 仞: a unit of length, in ancient times, seven feet or eight feet as a unit; She:

The unit of length, in ancient times, was rounded up by thirty miles when marching. Fathom: a unit of length, eight feet for a fathom.

In ancient times, the common units of capacity were: stone, bean and dun. In ancient times, common units of weight were: stone and jun. In ancient times, the common units of length were: 跬, 仞, she, and xun.

In terms of the process of human evolution, 1From animals that live in the water, they evolve into reptiles. 2.

After coming to land, mammals appear. 3.Some of them choose to continue living on the shore, some climb towards the trees, some start a life of flying, some continue to live in the trees, and some go down from the trees to the ground.

4.Some of the animals that descend to the ground develop into a life in the soil, some begin to live in a jumping life (such as kangaroos), some return to the shore to live, some are transformed into amphibians (or they may have been converted into amphibious when they first come to land), and then they return to the water, some have adapted to grassland life, some have returned to the river, and some have chosen to go up the trees again. 5.

And the animals that stay in the trees and continue to live in the trees, begin to glide. 6.Some of the animals that live in the trees continue to live in the trees, while the other choose to go down to the ground.

7.Some of the animals that descended to the ground chose to walk on all fours most of the time (e.g., gorillas), while others chose to walk upright on their hind limbs on the ground, and eventually evolved into modern humans. All living things evolved from aquatic plankton The ancient surface of the earth was very "irritable" volcanic eruptions brought organic matter underground to the surface and then flowed into the newly formed primordial ocean, and these materials evolved into microorganisms in the water through countless evolutions, evolved into microorganisms in the water, and evolved into different organisms through temperature, the emergence of oxygen in the atmosphere, the changes and formation of the environment, and their own mutations, etc., in fact, there were many more kinds of organisms at that time than now, because of the control of the laws of nature, the survival of the fittest The organisms that have adapted to the environment have survived, and they have mutated and evolved from generation to generation, resulting in the beautiful and colorful world that we have now, and so has the growth of human beings, so once the creatures are eliminated, they can't continue to be in the world, so nature is cruel, and we need to protect the diversity of life.

The devil knows how it came to be, it's been so long, all science is speculation, what dinosaur age, ice age, several times, and prehistoric civilizations.

The change of the environment, yes, the organisms have to adapt to different forms, and through natural selection, different organisms are formed, and finally the current situation has emerged.

Plants create nutrients, green; Animals bring joy and contribute their skin, flesh and other things of value; Man, on the other hand, is the ruler of the earth; All three are indispensable.

It should be said that this is the power of science.

This ... This is to be asked? Uh, the scientists don't even know about it, right?

Because it's natural evolution.

Because it's all on earth.

Cordyceps sinensis is not a creature that is both an animal and a plant. Cordyceps sinensis is a fungus of Cordyceps fungus, the spores mature and scatter, germinate into hyphae, burrow into the larvae of manta moths, and absorb nutrients from the larvae. In the spring and summer of the following year, the temperature and weather are suitable, and mycelium grows out of the mouthparts of the larvae.

In other words, it is a mixture of fungi that grow in the body of an animal and then grow.

Organisms that are both animals and plants are: green leaf sea slugs, euglena insects, etc., which have both animal and plant characteristics. If the euglena has eyepoints (photosensitivity) and flagella (locomotion), it should be an animal. But it also has chloroplasts (which perform photosynthesis).

"So many animals and plants are the protectors of our human beings".

It is because of life that the world is colorful and wonderful. Living systems are made up of us humans and many other living animals, plants, and other living members. The members of the living system are our friends and the protectors of our humanity.

Without plants, life would not be able to continue to reproduce. Because only plants can photosynthesize. Plants use chlorophyll to feed themselves by making carbon dioxide or hydrogen sulfide and water into organic nutrients when exposed to visible light. Humans and animals can't do that.

We know that animals survive by eating other animals and plants. Therefore, plants are the material basis for the existence of living systems, and plants are an important link in the food chain. Plants are very important in the whole living system.

We humans are inseparable from animals and plants for eating, drinking, and wearing. Whether it is meat, eggs, milk, grain, rape, etc., it is inseparable from animals and plants, whether it is cotton, linen, silk or woolen fur, it is inseparable from animals and plants. That's why we say that animals and plants are the protectors of our human beings.

Plants are the material basis that sustains living systems. Without plants, living systems are like water without a source. A living system cannot be without any link in the food chain.

Humans cannot survive without plants. By not collecting wild plants and protecting the surrounding environment, we are protecting ourselves. "So many animals and plants are the protectors of our human beings".
