Question

A pollen tube of a flowering plant is the ______.

Options

• male gamete

• female gamete

• germinating spore

• male gametophyte

Answer 1

A pollen tube of a flowering plant is the male gametophyte.

Explanation:

The pollen tube is a structure that develops from the pollen grain (male gametophyte) after it lands on the stigma. It grows and carries the male gametes toward the ovules for fertilization. Hence, the pollen tube represents the male gametophyte, not the male gamete itself or the female gamete.
