The three states of matter are solid, liquid, and gas. Solids have a fixed shape and volume; liquids have a fixed volume but take the shape of their container; gases have no fixed shape or volume.

Question 4

What gas do plants absorb from the air during photosynthesis?

Accepted Answer

Carbon dioxide

Answer

During photosynthesis, plants absorb carbon dioxide from the air through tiny holes in their leaves called stomata. They combine it with water and light energy to make glucose.

Question 5

What is the function of the roots of a plant?
