The process of photosynthesis requires three things: Light, Carbon dioxide and water. But, if you have too much light, than the other 2 ingredients become limiting and photosynthesis can no longer increase with the level of light. When this occurs, leaves can experience sunburn damage.

Plants rely on the energy in sunlight to produce the nutrients they need. But sometimes they absorb more energy than they can use, and that excess can damage critical proteins. To protect themselves, they convert the excess energy into heat and send it back out.

High CO2 levels cause plants to thicken their leaves, which could worsen climate change effects, researchers say. Plant scientists have observed that when levels of carbon dioxide in the atmosphere rise, most plants do something unusual: They thicken their leaves.

What happens to the excess oxygen produced during photosynthesis? It is used as an energy source by plant cells. It is released into the air and is used by other organisms for respiration. It is converted into heat energy.

During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

The overall reaction for photosynthesis as given above is a simplification. The hydrogen is needed for the second stage of reactions and the oxygen is released by the plant as a waste product. In the reactions of the second stage, the hydrogen is combined with carbon dioxide to make glucose.

The Light Reactions

It is convenient to divide the photosynthetic process in plants into four stages, each occurring in a defined area of the chloroplast: (1) absorption of light, (2) electron transport leading to the reduction of NADP+ to NADPH, (3) generation of ATP, and (4) conversion of CO2 into carbohydrates (carbon fixation).

Plants, through the process of photosynthesis, make use of the sunlight to energise and generate glucose through the available water and carbon dioxide. Through cellular respiration, pyruvate in turn gives ATP (adenosine triphosphate). …

The three major events that occur during the process of photosynthesis are: > Absorption of light energy by chlorophyll. > Conversion of light energy to chemical energy and splitting of water molecules into hydrogen and oxygen.

Two events that occur during photosynthesis are : (i) Absorption of light energy by chlorophyll. (ii) Conversion of light energy into chemical energy and splitting of water molecules into hydrogen and oxygen.

Answer: Because roots are under the ground and no transfer of air take place. Sunlight cant be reached there.

The stomata must be open during the daylight hours to let oxygen and carbon dioxide pass through. While they are open, water vapor escapes into the atmosphere (transpiration). Transpiration is the loss of water through stomata, so, more stomata are found on the lower surface to prevent excessive loss of water.

What can treat large facial pores?

1. Use only non-comedogenic skin care products and makeup. The word “non-comedogenic” means the product won’t clog your pores.
2. Cleanse your face twice a day.
3. Use retinol.
4. Treat acne.
5. Protect your face with sunscreen every day.
6. Exfoliate.
7. Be gentle with your skin.
8. Treat sagging skin.
