Energy and the Cell
Cells, except bacteria, have organelles called mitochondria (mi tuh KAHN dree uh).
An important process called cellular respiration takes place inside a mitochondrion.

5. The World of Cells 1
Energy and the Cell
Cellular respiration is a series of chemical reactions in which energy stored in food is converted to a form of energy that the cell can use.

6. The World of Cells 1
Energy and the Cell
This energy is released as food and oxygen combine.
Waste products of this process are carbon dioxide and water.

Nature's Solar Energy Factories
Animals obtain food from their surroundings.
Plants, algae, and many types of bacteria make food through a process called photosynthesis (foh toh SIHN thuh sus).

Nature's Solar Energy Factories
Most photosynthesis in plants occurs in leaf cells.
Inside these cells are green organelles called chloroplasts (KLOR uh plats).

9. Nature's Solar Energy Factories

Nature's Solar Energy Factories
During plant photosynthesis chloroplasts capture light energy and combine carbon dioxide from the air with water to make food.
As the plant needs energy, its mitochondria release the food's energy.
