Zygote develops into the...............and the primary endosperm cell forms the.............tissue in angiosperm:-

Options

A. Embryo, endosperm
B. Endosperm, embryo
C. Seed, embryo
D. Endosperm, seed

Answer

To answer the question, we need to understand the processes that occur in angiosperms during fertilization and subsequent development.

### Step-by-Step Solution:

1. **Understanding Fertilization in Angiosperms**:
- In angiosperms (flowering plants), a unique process called double fertilization occurs. This involves the fusion of two male gametes (sperm cells) with different female structures in the ovule.

2. **Formation of the Zygote**:
- One of the male gametes fuses with the egg cell (female gamete), resulting in the formation of a zygote. The zygote is a diploid structure, meaning it contains two sets of chromosomes (one from each parent).

3. **Development of the Zygote**:
- The zygote then develops into the embryo. This is the early stage of the new plant that will eventually grow into a mature plant.

4. **Formation of the Primary Endosperm Cell**:
- The second male gamete fuses with the central cell, which contains two polar nuclei. This fusion results in the formation of the primary endosperm nucleus, which is a triploid structure (three sets of chromosomes).

5. **Development of Endosperm Tissue**:
- The primary endosperm nucleus then develops into the endosperm tissue. The endosperm serves as a food reserve for the developing embryo within the seed.

6. **Final Answer**:
- Therefore, the zygote develops into the **embryo**, and the primary endosperm cell forms the **endosperm** tissue in angiosperms.

### Final Answer:
Zygote develops into the **embryo** and the primary endosperm cell forms the **endosperm** tissue in angiosperm.
