• Nitrogen

• Oxygen

• Proteins

• Glucose (sugars)

The ORIGINAL source of all energy in photosynthesis is

• The Earth

• The Sun

• The Moon

• Seeds that we plant

Most plants appear green because chrorophyll

• absorbs green light

• reflects green light

• absorbs all light

• Absorbs yellow and blue light

• nitrogen

• hydrogen

• carbon dioxide

In which organelle does photosynthesis occur?

• The nucleus

• The cytoplasm

• chloroplasts

• The cell wall

What do plants do with glucose?

• They use it for food

• the respire it in the atmosphere

• The provide food for other organisms

• They store it for later use

What is the purpose of the stomata?

• Stomata are part of the root system of a plant

• Small openings on the bottom of the leaf that allow oxygen, carbon dioxide and water vapor to pass though.

• Stomata are an organelle in the cell where photosynthesis occurs

• Stomata are the storage organelles for plant cells
