What is the ultimate source of energy for photosynthesis?

The Sun is an infinite (at least in terms of human time scales) and renewable source of energy which is also by far the most important source of energy for us. Primary productivity (photosynthesis) is driven by sunlight and all our fossil fuels are derived from plants which existed millions of years ago.

Do the sun is only source of energy for photosynthesis?

Solution: Sunlight is the source of energy for photosynthesis.

What brings energy to a plant?

Sunlight provides the energy needed for photosynthesis to take place. In this process carbon dioxide and water are converted into oxygen (a waste product that is released back into the air) and glucose (the source of energy for the plant).

What do plant leaves absorb?

Chlorophyll’s job in a plant is to absorb light—usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide (absorbed from the air) and water into glucose, a type of sugar.

Do plants release carbon dioxide or oxygen?

Plants use photosynthesis to capture carbon dioxide and then release half of it into the atmosphere through respiration. Plants also release oxygen into the atmosphere through photosynthesis.

How do plants get the carbon dioxide they need for photosynthesis?

Plants get the carbon dioxide they need from the air through their leaves. It moves by diffusion through small holes in the underside of the leaf called stomata . … These let carbon dioxide reach the other cells in the leaf, and also let the oxygen produced in photosynthesis leave the leaf easily.
