FAQs on Seed: Structure & Types Video Lecture - Biology Class 11 - NEET

1. What is the definition of seed structure?

Ans. Seed structure refers to the physical arrangement and organization of the different parts of a seed, including the seed coat, endosperm, and embryo. It determines the overall shape, texture, and size of the seed.

2. What are the different types of seed structures?

Ans. There are three main types of seed structures: monocotyledonous seeds, dicotyledonous seeds, and gymnosperms. Monocotyledonous seeds have a single cotyledon or seed leaf, dicotyledonous seeds have two cotyledons, and gymnosperms have naked seeds without a protective ovary wall.

3. How does the seed structure contribute to seed dispersal?

Ans. The seed structure plays a crucial role in seed dispersal. Some seeds have adaptations like wings or hooks on the seed coat that enable them to be carried by wind or animals. Others have fleshy fruits that are eaten by animals, and the seeds are later dispersed through their droppings.

4. What is the significance of the seed coat in seed structure?

Ans. The seed coat, also known as the testa, is the outermost layer of the seed. It provides protection to the embryo and endosperm from mechanical damage, pathogens, and dehydration. It also acts as a barrier to water and gas exchange, preventing premature germination.

5. Can you explain the structure of a gymnosperm seed?

Ans. Gymnosperm seeds have a unique structure compared to other seed types. They lack a true enclosed ovary and have naked seeds. The seed structure consists of a seed coat, an embryo, and a food source called the megagametophyte. Unlike angiosperms, gymnosperms do not have fruits or flowers.
