Plant cells carry out photosynthesis inside a green organelle called the .
This organelle contains a green pigment called , which absorbs
energy and uses it to turn carbon dioxide and water into glucose.
The outer rigid layer of a plant cell is the cell wall, which is made of a tough material called .
Inside the cell, a large fluid-filled sac called the stores water and keeps the cell firm and .
When the cell needs energy, the release it from glucose through the process of respiration.
