Photosynthesis

Photosynthesis

Photosynthesis- is a process used by plants and other organisms to convert light energy, normally from the Sun, into chemical energy that can be later released to fuel the organisms' activities.

How does water enter a plant and get to the leaves?

  1. Water is taken up by the roots of a plant and is transported into a plant to the leaves and put into the air.

How does CO,2 enter the leaf?

2.


Plants get carbon dioxide from the air through their leaves. The carbon dioxide diffuses through small holes in the underside of the leaf called stomata.

Where does photosynthesis occur in the plant?

3.


  1. Photosynthesis occurs inside plant cells in small things called chloroplasts- (mostly found in the mesophyll layer) contain a green substance called chlorophyll.

Why is sunlight important to the process of photosynthesis?

4.


Because the process of photosynthesis occurs when green plants use the energy of light to change carbon dioxide (CO2) and water (H2O) into carbohydrates.

What is a waste product for the plant and how is it removed from the plant?

5.


Green plants produce carbon dioxide and water as respiratory products. In green plants, the carbon dioxide released during respiration gets utilized during photosynthesis.

What does the plant do with the sugar it makes?

6.


The chlorophyll uses light energy from the sun to combine carbon dioxide and water to produce sugar.

What are the final products of photosynthesis and how are they important to life on this planet?

7.


The final products of photosynthesis are glucose (sugar) and oxygen. The oxygen allows animals and other organisms to breathe and produce energy through cellular respiration.
