Photosynthesis

​Photosynthesis

​Plants make the food they need through a process called photosynthesis. The process begins when the chlorophyll inside plant's cell structures called chloroplasts absorbs light energy, usually from the sun. At the same time, carbon dioxide enters the plant throught its stomata in the leaves, and its roots absorb water from the soil.

Multiple Choice

The process begins when chlorophyll traps __________?

• sugar

• light energy

• oxygen 

• carbon dioxide

Multiple Choice

What do plants need to create energy?

• water and sugar

• sugar and oxygen

• light, carbon dioxide, and water

• carbon dioxide and oxygen

Multiple Choice

Photosynthesis takes place in the ?

• mitochondria

• chloroplast

• chlorophyll

• nucleus

Multiple Choice

Chlorophyll traps light energy to make?

• dirt

• metal

• food

• iron

​Photosynthesis Part 2

​The water, carbon dioxide, and light combine in the leaves to make sugar, which the plant uses to grow. Any sugar the plant doesn't need right away is stored as starch in the roots. Then the plants release oxygen and water vapor through their leaves.

Multiple Choice

What do plants release (outputs) through their leaves?

• carbon dioxide and sugar

• oxygen and water vapor

• sugar and water

• carbon dioxide and oxygen

Multiple Select

What happens during photosynthesis? (pick all answers)

• plants stop growing

• plants make sugar in their leaves

• plants create the food they need

• plants store the sugar in their roots

Multiple Select

When plants give off oxygen, where does it go? (pick all answers)

• to the leaves

• to the roots

• in the air

• to humans to breathe

Multiple Choice

What do plants need (inputs) to complete to create energy?

• carbon dioxide and sugar

• oxygen and water vapor

• light, carbon dioxide, and water

• light and water

Multiple Choice
