The cells fo the endosperm are filled with reserve food material and are used for the nutrition of developing embryo is gernally a ____________ in angiosperms

Options

A. triploid tissue
B. diploid tissue
C. haploid tissue
D. hexaploid tissue

Answer

To answer the question regarding the nature of endosperm in angiosperms, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Endosperm Formation**:
- In angiosperms, the endosperm is formed through a process known as double fertilization. This involves the fusion of one male gamete with two polar nuclei.

2. **Identifying the Genetic Makeup**:
- The male gamete is haploid (1n), while the two polar nuclei are diploid (2n). When these fuse, they create a primary endosperm nucleus (PEN).

3. **Determining the Ploidy Level**:
- The fusion of one haploid male gamete with two diploid polar nuclei results in a triploid (3n) primary endosperm nucleus. This is because 1 (from the male gamete) + 2 (from the polar nuclei) = 3.

4. **Conclusion about Endosperm**:
- The endosperm, therefore, is a triploid tissue, which serves as a source of nutrition for the developing embryo in angiosperms.

5. **Final Answer**:
- The cells of the endosperm are filled with reserve food material and are used for the nutrition of the developing embryo, which is generally a **triploid tissue** in angiosperms.
