What are the physiological activities that green plants perform under light?

Photosynthesis, transpiration, and respiration.

Photosynthesis of green plants refers to the process in which green plants use light energy to synthesize organic matter such as carbon dioxide and water into organic matter in chloroplasts, release oxygen, and at the same time convert light energy into chemical energy and store it in the synthetic organic matter The site of visible photosynthesis is chloroplasts, and the condition is light; Respiration refers to the process of decomposing organic matter into carbon dioxide and water and releasing energy in the ** chondria, which can be seen as long as it is a living cell. Transpiration refers to the process of green plants dissipating water in the body from the stomata of the leaves to the atmosphere in the form of water vapor From the above, it can be seen that the photosynthesis of plants is affected by light, so the physiological activities that plants can carry out during the day or under light are: photosynthesis, respiration and transpiration

Answer] Chain of Things: d

Knowledge points] This question examines the knowledge of photosynthesis, transpiration and respiration of green plants.

Answer] d. Analysis] The condition of photosynthesis is light, the place is chloroplast, and photosynthesis must be carried out under light; Respiration and transpiration can be carried out in the presence or absence of light. Respiration can be carried out at all times and moments in all living cells, and the factors that affect respiration are mainly the content of water and oxygen.

Transpiration is affected by temperature, humidity of the air, and the flow of air. Under the light coarse sage, the basic conditions for photosynthesis, respiration, transpiration, and root absorption are all in place, so they can all be carried out. Therefore, D is selected for this question.

Analysis] The condition of photosynthesis is light, the place is chloroplast, and photosynthesis must be carried out under light; Guess that respiration and transpiration can be carried out in both light and light. Respiration can be carried out every moment of the rise in all living cells, and the main factors that affect respiration are the content of water and oxygen. Transpiration is affected by temperature, humidity of the air, and the flow of air.

Under light, the basic conditions for photosynthesis, respiration, transpiration, and root absorption are all in place, so they can all enter the ear or row. Therefore, D is selected for this question.

Photosynthesis, transpiration, and respiration.

Photosynthesis, respiration, transpiration and so on. If you want to take the test, just the first two.

This physiological activity is so broadly said, photosynthesis, respiration, transpiration...

1.Respiration 2Transpiration 3Photosynthesis 4Both water and inorganic salts can be transported.

Let me help you sort out the requirements of the above four processes.

The first is photosynthesis: the site will change depending on the plant type, but the required conditions remain the same, light, photosynthesis related to pigments, enzymes, ATP, coenzyme 2, water and carbon dioxide.

Respiration: reaction feedstock (glucose), enzymes, oxygen, and reduced hydrogen.

Absorption: There are two situations, osmosis and swelling, the former requires a semi-permeable membrane and a concentration difference between the two sides, while the latter requires some hydrophilic substances (such as cellulose and protein).

Transpiration: It can be carried out under normal conditions, but the stomatal closure will stop in the case of high temperatures in summer.

D: Ah, I look at the answers to some test papers.

Brother 12 questions. I don't understand why.

If you know why, please upload.

The physiological activities of green plants include: photosynthesis, transpiration, respiration a, photosynthesis, respiration and transpiration of plants under light, and respiration and transpiration of plants in the dark, so it does not conform to the topic

b. The absorption of inorganic salts by roots is a process of active transportation, so it consumes energy, so it does not conform to the topic c. The transpiration pull generated by transpiration promotes the absorption and transportation of water by plants, so it does not conform to the topic

d. When the stomata are opened, the water in the leaf absorbs heat and becomes water vapor, which diffuses into the outside air through the stomata Therefore, the stomata are the "gateway" for the transpiration and water loss of the plant body, and it is also the "window" for the gas exchange between the plant body and the outside world

Therefore, d

Answer D analysis: This question examines the three major physiological effects of plants, among which only photosynthesis is affected by light, while respiration and transpiration are not affected by light

Answer: The condition of photosynthesis is light, the place is chloroplast, and photosynthesis must be carried out under light; Respiration is the process of decomposing organic matter into carbon dioxide and water with the participation of oxygen, while releasing energy; Plant transpiration refers to the process by which water in the plant body is lost into the air in the form of gas Respiration and transpiration can be carried out with and without light Transpiration promotes the absorption of water and inorganic salts by plants from the soil, with and without light

Therefore, the life activities that green plants can carry out under light are photosynthesis, respiration, transpiration, absorption of water and inorganic salts

Comment: It is known that photosynthesis in plants must be carried out under the conditions of light, and the respiration and transpiration of plants can be carried out under both light and non-light conditions

Therefore, d

High 3 Biology] Photosynthesis and Respiration.

Answer D analysis: This question examines the various physiological activities of green plants, first of all, identify what physiological activities plants have

Answer: The physiological activities of green plants include: photosynthesis, transpiration, and respiration

a. Plants carry out photosynthesis, respiration and transpiration under light, and plants carry out respiration and transpiration in the dark, so it does not conform to the topic

b. The absorption of inorganic salts by roots is a process of active transportation, so it consumes energy, so it does not conform to the topic

c. The transpiration tension produced by transpiration promotes the absorption and transportation of water by plants, so it does not conform to the topic

d. When the stomata are opened, the water in the leaf absorbs heat and becomes water vapor, which diffuses into the outside air through the stomata Therefore, the stomata are the "gateway" for the transpiration and water loss of the plant body, and it is also the "window" for the gas exchange between the plant body and the outside world

Selection: Comments: The various physiological activities of plants can be grasped through comparative understanding

Answer B In addition to photosynthesis under light, green plants also carry out respiration and transpiration, the transpiration tension generated by transpiration promotes the roots of plants to continuously absorb water from the soil, and the stomata are the "gateways" for leaves to emit water and exchange gases with the outside world.
