Plant Nutrition and Photosynthesis Concepts

What is the process called when plants make their own food?

• Respiration

• Digestion

• Photosynthesis

• Germination

What kind of energy helps plants make their food?

• Wind energy

• Water energy

• Sunlight energy

• Heat energy

What are the main things a plant needs to make its food?

• Soil, wind, and rain

• Water, carbon dioxide, chlorophyll, and sunlight

• Oxygen, sugar, and roots

• Flowers, fruits, and seeds

Which part of a plant takes in water from the ground?

• Leaves

• Flowers

• Roots

• Stems

After roots absorb water, where does it go next in the plant?

• To the flowers

• To the fruits

• To the stem and then to the leaves

• It stays in the roots

How does carbon dioxide gas get into a plant's leaves?

• Through the roots

• Through small openings called stomata

• Through the flowers

• Through the stem

What are stomata used for in plants?

• To absorb water from the soil.

• To release oxygen and absorb carbon dioxide.

• To make the plant green.

• To grow flowers.

What is the green substance in leaves that helps them catch sunlight?

• Water

• Stomata

• Chlorophyll

• Carbohydrate

Besides oxygen, what other important thing do plants make during photosynthesis?

• Water

• Carbon dioxide

• Carbohydrates (food)

• Chlorophyll

What happens to the food (carbohydrates) that plants make?

• It is released into the air.

• It is stored only in the roots.

• It is used by the plant and stored as food in fruits or tubers.

• It turns into sunlight.
