The phenomenon of plant life does not explain what plants are alive with

Such as photosynthesis.

Tropic motion (phototropism, geotropism, etc.).

Cytoplasmic circulation.

Stomatal opening and closing.

Starfish are divided into halves and can become several starfish.

Wildfires burn inexhaustibly, and spring breezes blow and regenerate.

Plants are living in their own right. It's just that the life performance of plants is different from that of human beings. The manifestation of human life is the ability to breathe.

I can move. I am happy and sad. And plants, such as trees, are always there, and you can't see their joys and sorrows.

His life should be manifested by growing new leaves, growing taller little by little.

If you judge by the standard of human life performance, you can't see the respiration of plants in the first place. You can't see the joys and sorrows of plants. Naturally, these manifestations do not indicate that plants are alive.

Yes, if there are leaves and flowers, it means that the plant is alive. If plants are not alive, aren't they stones and soil? So.

Plants are also alive. If you praise a pot of flowers every day, then it will bloom very well, and if you scold a pot of flowers every day, then it will not bloom well, or it will not look good. Therefore, plants are also alive and emotional.

Summary. Have.

A vegetative person is supposed to have the characteristics of life, he has a heartbeat, his brain is damaged when he breathes, he has no consciousness, and he cannot move consciously.

Do vegetative people have the characteristics of life?

What is the main basis for maintaining homeostasis for a certain function of the human body?

Negative feedback 1Maintaining homeostasis for a certain function of the human body mainly depends on (negative feedback)2In vivo control system - feedback control system - negative feedback. Negative feedback reduces the activity of the control part, which is of great significance in maintaining the homeostasis of the body's physiological functions.

Like other living organisms, plants are living and have many life phenomena. Plants will absorb nutrients for growth and development, and will also metabolize and reproduce, and will also have self-defense behaviors in the face of danger, will change their form to adapt to the environment for growth, and can carry out genetic inheritance and mutation.

Many people know that animals are alive, but they don't know whether plants are alive, in fact, plants are also living creatures. In the process of growth, plants, like other living objects, have many life phenomena and absorb nutrients to enable them to grow and reproduce.

1. Growth and development

Plants, like other living organisms, are absorbing enough nutrients to replenish their own nutrients so that they can grow normally. Just as humans have different stages of development, plants also have their own seedling stage, maturity stage, will go through their own stage of development, and finally go to death.

2. Metabolism

Metabolism is an important feature of the existence of living organisms, and plants are constantly metabolizing. Plants absorb light, water, oxygen, salts and other substances in their growing environment, photosynthesize to make themselves strong, and breathe to expel excess gases from the body.

3. Reproduction

Only living organisms reproduce and reproduce, so that they can be passed on from generation to generation. Plants also bear fruit and breed, so as to reproduce and prolong their lives. And this kind of reproduction is also a phenomenon of plant life activities, which is an important manifestation of its life.

4. Self-defense protection

Just as humans defend themselves in the face of danger, plants, as living organisms, also defend themselves. Many plants contain toxins to avoid damage to their own lives, and many plants also release odors that animals do not like, so as to protect themselves.

5. Adapt to the environment

Just as chameleons adapt to their environment and change color to make their lives better, plants adapt to their environment so that they can survive. For example, cacti in the desert will make their leaves smaller and reduce water evaporation, thus maintaining their growth needs and not dying from lack of water.

6. Genetic variation

Genetic variation is also a common life activity in living organisms, just like humans inherit genes, and this is also the case in plants. The seeds harvested in the watermelon vertical and then planted in the soil will produce watermelon, which is a kind of genetic inheritance in the plant.

1. A living plant is alive because it has many life phenomena.

2. Life phenomenon 1, can grow: plants can grow. They can absorb nutrients from the outside world, synthesize organic substances in the body, and help themselves grow by breaking them down to obtain energy.

2. Can reproduce: Plants can reproduce. They can reproduce the next generation through sexual reproduction or asexual reproduction, and the process of reproduction itself is a life activity.

3. Can be hereditary: The genes of plants are heritable. Children born through sexual reproduction have the genes of both parents, and offspring that are bred through asexual reproduction also have the genes of the previous generation. This proves that it has life.

4. Able to adapt to the environment: Plants can gradually change some of their own traits to adapt to the environment. For example, when growing in a water-starved environment for a long time, the leaves of the cactus become needle-shaped to help it reduce the evaporation of water from its body. It's also a sign that they have life.

Big trees have life, small grass has life. Spit out shoots in spring, bloom in summer, bear fruit in autumn, and fall leaves in winter, and the cycle repeats.

1. Some towering trees are also common in daily life, and the reason why these trees are tall is because of the development of stems, an organ of plants we are going to talk about here. We call this kind of stem that grows on its back to the ground an erect stem.

However, plants are not all erect and tall, and some plants have slender and soft stems that cannot stand upright and can only grow upwards around other objects, which is called a winding stem. Such as the stems of morning glory and honeysuckle. In addition, there are some plants such as cucumbers, grapes, etc., although their stems are also slender and soft, but they can neither grow upright nor wrap around other objects, but they can coil on other objects with tendrils growing on the stems to make the stems grow high, this kind of stem is called climbing stem.

The stems mentioned above all act as bridges between roots and leaves, and constantly transport nutrients between roots and leaves, which are also plant life phenomena.

2. The most prominent life phenomenon of plants is the photosynthesis of plants.

Photosynthesis, that is, photosynthesis, refers to the biochemical process of chloroplasts, green plants, animals and certain bacteria, under the irradiation of visible light, through light reaction and carbon reaction (formerly known as dark reaction), using photosynthetic pigments to convert carbon dioxide (or hydrogen sulfide) and water into organic matter, and release oxygen (or hydrogen). At the same time, there is also an energy conversion process that converts light energy into chemical energy in organic matter. Photosynthesis is the sum of a series of complex metabolic reactions, which is the basis for the survival of the biological world and an important medium for the earth's carbon-oxygen balance.

3. In addition, the life phenomena of plants include osmosis and water absorption, absorption of mineral elements, respiration, plant tropism, perceptual movement, plant growth and development, flowering, fruiting, defoliation, etc.

Talking about my understanding of the question, plants are alive, and the main manifestations are:

1. Have a certain life cycle Like us humans, we also experience from childhood to adulthood, from life to death. During this period, flowering and fruiting (most plants), germination, branch pulling, and leaf loss are all specific manifestations of some life activities of plants at different life stages and in different growing seasons.

2. Plants have physiological and biochemical reactions represented by photosynthesis, respiration, transpiration, etc., to ensure normal growth and development.

3. The leaves of plants have phototropism, and the roots have the properties of adapting to the environment, such as territorial fertilization (fertile soil).

4. Plants reproduce their offspring in different ways.

The power of seeds.

There is such a story.

Someone asked: What is the most powerful thing in the world? The answers were very varied, some said elephants, some said lions, and some joked that it was King Kong. How much strength King Kong has, of course, everyone doesn't know.

As a result, all these answers are completely wrong, and the most powerful thing in the world is the seeds of plants. The power that a seed can manifest is simply beyond all else.

The human skull is very densely bonded and strong. Physiologists and anatomists tried everything to separate it completely, without success. Later, someone suddenly invented a method, which is to put the seeds of some plants in the skull to be dissected, and give temperature and humidity to make the seeds germinate.

As soon as they sprouted, these seeds parted with terrible force the bones that could not be separated by any mechanical force. Plant seeds are so powerful.

This may be a little special and not easy for ordinary people to understand. So, have you ever seen a small grass spawned under rubble and rocks? In order to yearn for the sunshine and to fulfill its will to live, no matter how heavy the stones on it are and how narrow the stones are between them, it will always twist and turn, but it will be tenacious and unyielding to penetrate the ground.

Its roots dig into the soil, its buds push upwards, a force majeure that prevents its rocks from being overturned by it. The power of a seed is so great.

No one calls Xiaocao a Hercules, but its power is indeed incomparable. This force is a life force that is invisible to ordinary people. As long as life exists, this power will be revealed, and the stones above it are not enough to stop it, because this is a force of "long-term resistance", elastic, a force that can bend and stretch, a force that is resilient, and does not achieve its goal.

If it does not fall in the fertile soil but in the rubble, the seed of life will never be pessimistic and sigh, and it believes that there is resistance to tempering. The grass that comes with fighting spirit at the beginning of life is the tough grass, and only this grass can sneer at the potted flowers raised in the glass shed.

Phenomena are creatures, creatures, me.

To animals. Don't tell stories of love for life, I don't want those. For example:

At night, I was writing under the lamp, and a moth kept flying over my head, harassing me. As soon as it stopped, I reached out and grabbed it. But it struggled, flapping its wings as hard as it could, and I felt a life force leaping in my hands, so strong!

So vivid! The moth desire shocked me, and I couldn't help but let it go!

After that, write about your feelings, please hurry up if you are troubled.

There are too many, such as photosynthesis, and the growth of plants is also a phenomenon of life.
