Understanding Photosynthesis and Seeds

What is the main purpose of photosynthesis in plants?

• To produce oxygen

• To make food

• To absorb water

• To grow taller

Which part of the seed grows into a new plant?

• Seed coat

• Embryo

• Cotyledon

• Root

Why is sunlight important for photosynthesis?

• It helps the plant to breathe

• It provides energy for the process

• It keeps the plant warm

• It helps the plant to absorb water

What role does water play in photosynthesis?

• It is used to transport nutrients

• It is a reactant in the process

• It provides shade for the plant

• It helps the plant to stand upright

Which of the following is the first stage of seed germination?

• Seedling growth

• Root emergence

• Seed coat breaking

• Leaf development

Identify the part of the seed that stores food for the developing plant.

• Embryo

• Seed coat

• Cotyledon

• Root

Which of the following is a type of seed?

• Leafy seed

• Flower seed

• Monocot seed

• Woody seed

Explain why water is essential for seed germination.

• It helps the seed to float

• It softens the seed coat and activates enzymes

• It provides nutrients to the seed

• It keeps the seed warm

Describe the process of photosynthesis in simple terms.

• Plants use sunlight to make food from water and carbon dioxide

• Plants absorb water and grow taller

• Plants release oxygen into the air

• Plants use soil nutrients to grow

What happens to a seed during germination?

• It dries up and becomes hard

• It absorbs water and begins to grow

• It changes color

• It falls off the plant
