Parts of a Seed
Q: What are the main parts of a seed?
Answer:
The main parts of a seed are the seed coat, the embryo, the endosperm, and the perisperm.
Q: What is the function of the seed coat?
Answer:
The seed coat provides protection and helps in the dispersal of seeds. It also prevents mechanical damage and the entry of pathogens.
Q: What does the embryo in a seed consist of?
Answer:
The embryo consists of epicotyl, hypocotyl, plumule, radicle, and cotyledons. These tissues give rise to the root, stem, and leaves of the new plant.
Q: What is the role of the endosperm in a seed?
Answer:
The endosperm serves as a nutrient reservoir, providing nourishment to the developing embryo. It is rich in carbohydrates, proteins, and lipids.
Q: What is the perisperm in a seed?
Answer:
The perisperm is the persistent nucellus, which is not present in all seeds. It is derived from the nucellus and may serve as a nutrient storage tissue.
Parts of Seed
Parts of Seed: The seed consists of several important parts that contribute to plant growth and reproduction. A seed is composed of the seed coat, embryo, endosperm, and sometimes the perisperm. The seed coat provides protection and aids in seed dispersal. The embryo contains tissues that give rise to the root, stem, and leaves of a new plant. The endosperm serves as a nutrient source for the developing embryo, while the perisperm, if present, acts as a nutrient storage tissue.
