In angiosperms, pollen tube liberates its male gamets into

Options

A. (a) central cell
B. (b) egg cell
C. (c) synergids
D. (d) antipodal cells

Answer

To answer the question "In angiosperms, pollen tube liberates its male gametes into," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Structure**: In angiosperms, the pollen tube is a structure that develops from the pollen grain after it lands on the stigma of a flower. It grows down through the style and into the ovule, where the embryo sac is located.

2. **Identifying the Target Cells**: The pollen tube carries two male gametes. Upon reaching the embryo sac, it typically enters through specific cells known as synergids. These cells are located at the micropylar end of the embryo sac.

3. **Pollen Tube Entry**: The entry of the pollen tube into the synergids is facilitated by a structure called the filiform apparatus, which helps guide the pollen tube to the correct location.

4. **Fertilization Process**: Once the pollen tube enters the synergids, one of the male gametes is released and fuses with the egg cell to form the zygote. The other male gamete is directed to the central cell, where it fuses with the polar nuclei to form the triploid endosperm, which serves as a nutritive tissue for the developing embryo.

5. **Conclusion**: Therefore, the correct answer to the question is that the pollen tube liberates its male gametes into the synergids.

### Final Answer:
The pollen tube liberates its male gametes into the **synergids**.
