Plant Growth, Development, and Response: Seed Structure

The video tutorial explains the various parts of seeds, including the seed coat, embryo, cotyledon, and endosperm. It describes how the seed coat protects the embryo, which remains dormant until conditions are favorable. The endosperm serves as a food storage tissue, nourishing the new plant. The video also covers the classification of angiosperms into monocots and dicots based on the number of cotyledons. Additionally, it discusses other seed structures like the epicotyl, hypocotyl, and radicle, which contribute to the development of the plant's stem, leaves, and roots.

What is the primary function of the seed coat?

• To facilitate photosynthesis

• To absorb water for germination

• To store nutrients for the plant

• To protect the embryo

In what form does the endosperm serve the new plant?

• As a protective layer

• As a food storage tissue

• As a growth hormone

• As a water reservoir

Which of the following plants is classified as a monocot?

• Rose bush

• Oak tree

• Maple tree

• Corn

What is the role of the epicotyl in plant development?

• It forms the roots

• It develops into the lower stem

• It gives rise to the upper stem and leaves

• It stores nutrients

Which part of the seed eventually forms the roots?

• Hypocotyl

• Cotyledon

• Radicle

• Epicotyl
