Seed Structure and Function Quiz

What is the function of the seed coat (testa)?

• To provide nutrients to the embryo

• To protect the embryo from environmental stresses

• To help in photosynthesis

• To develop into the plant's roots

What does the plumule develop into?

• The roots of the plant

• The aerial parts of the plant, including stems and leaves

• The seed coat

• The cotyledons

What is the role of the endosperm in a seed?

• To protect the embryo

• To provide the embryo with stored food reserves

• To develop into the plant's leaves

• To perform photosynthesis

Which type of plant has only one cotyledon?

• Dicots

• Monocots

• Both dicots and monocots

• Neither dicots nor monocots

Which of the following is an example of a dicotyledon?

• Grasses

• Lilies

• Beans

• Palms

Which of the following plants is a monocotyledon?

• Sunflowers

• Peas

• Lilies

• Beans

What is the first stage of seed germination?

• Enzyme Activation

• Radicle Emergence

• Imbibition

• Shoot Emergence

Why is oxygen availability important for seed germination?

• It provides energy needed for growth.

• It prevents dormancy.

• It helps in photosynthesis.

• It maintains seed coat integrity.

What is the effect of temperature on seed germination?

• It has no effect.

• Optimal temperatures vary depending on the plant species.

• It only affects water uptake.

• It is only important for light-dependent seeds.

What is the role of cotyledons during seed germination?

• They initiate metabolic activity.

• They function in photosynthesis or nutrient storage.

• They establish anchorage in the soil.

• They break down stored food reserves.
