Seed Structure and Function Concepts

The video tutorial explains the anatomy of a lima bean seed, focusing on four key parts: the seed coat, cotyledon, embryo, and true leaves. The seed coat protects the seed, the cotyledon provides stored food, the embryo develops into the plant, and the true leaves perform photosynthesis. The tutorial encourages viewers to dissect seeds at home to observe these parts.

What is the primary function of the seed coat?

• To facilitate photosynthesis

• To help the seed absorb water

• To protect the seed until it is ready to grow

• To provide nutrients to the seed

Which part of the seed acts as a food source until the seedling can perform photosynthesis?

• Cotyledon

• Seed coat

• Embryo

• True leaves

What happens to the cotyledon once the seedling can perform photosynthesis?

• It is no longer needed and shrivels away

• It becomes part of the root

• It continues to provide food

• It transforms into true leaves

What is the role of the embryo in a seed?

• To develop into the adult plant

• To perform photosynthesis

• To store food

• To protect the seed

Which part of the seed will eventually grow into the plant's stem and root?

• Cotyledon

• Embryo

• Seed coat

• True leaves

What are the first leaves that appear on a plant called?

• True leaves

• Cotyledon

• Embryo

• Seed coat

How do true leaves contribute to a plant's growth?

• By storing food

• By protecting the plant

• By absorbing water

• By performing photosynthesis

Why is the lima bean seed ideal for observing seed parts?

• It has a unique color

• It grows faster than other seeds

• It becomes large when soaked in water, making parts visible

• It is very small and easy to handle

Which part of the seed is described as 'super teeny tiny' and requires close observation?

• Cotyledon

• Seed coat

• True leaves

• Embryo

What is the main purpose of the video tutorial on seeds?

• To teach how to plant seeds

• To identify and understand the parts of a seed

• To compare different types of seeds

• To explain the history of seed cultivation
