The endosperm cells in angiosperms are

Options

A. (a) haploid
B. (b) diploid
C. (c) triploid
D. (d) tetraploid

Answer

**Step-by-Step Solution:**

1. **Understanding Angiosperms**: Angiosperms are flowering plants that belong to the highest category of the plant kingdom. They are characterized by the presence of seeds and fruits.

2. **Unique Features of Angiosperms**: One of the unique features of angiosperms is the presence of seeds that protect the embryo. Another significant feature is double fertilization.

3. **Double Fertilization Process**: In double fertilization, two male gametes from pollen grains play distinct roles:
- The first male gamete fuses with the egg cell (female gamete) to form a diploid zygote, which eventually develops into the embryo.
- The second male gamete fuses with the diploid polar nuclei present in the embryo sac to form a triploid structure known as the endosperm.

4. **Structure of the Seed**: In an angiospermic seed, the embryo (which develops from the zygote) is diploid, while the endosperm, which is a large part of the seed, is triploid.

5. **Function of Endosperm**: The endosperm serves a crucial role by providing nutrition and protection to the growing embryo.

6. **Conclusion**: Therefore, the endosperm cells in angiosperms are triploid in nature.

**Final Answer**: The endosperm cells in angiosperms are triploid (C).
