Pollen tube in angiosperms act as

Options

A. Agent of pollination
B. Agent of fertilization
C. Carrier of sperms
D. Stimulant of fertilization

Answer

**Step-by-Step Solution:**

1. **Understanding Angiosperms**: Angiosperms are flowering plants that produce seeds enclosed within a fruit. They are characterized by the presence of flowers and fruits.

2. **Role of Pollen Tube**: The pollen tube is a structure that forms after a pollen grain lands on the stigma of a flower. Its primary function is to facilitate fertilization.

3. **Process of Fertilization**: When a pollen grain germinates on the stigma, it undergoes a chemical reaction that leads to the formation of the pollen tube. This tube grows down through the style towards the ovule in the ovary.

4. **Carrying Sperm Cells**: The pollen tube carries the male gametes (sperm cells) from the pollen grain to the egg apparatus located in the ovule. This is crucial for the fertilization process, as the sperm must reach the egg to form a zygote.

5. **Conclusion**: Therefore, the pollen tube acts as the carrier of sperm in angiosperms, facilitating the process of fertilization by delivering the sperm cells to the egg.

**Final Answer**: The pollen tube in angiosperms acts as the carrier of sperm.
