Question

name the cell in male gametophyte of angiosperms which produces Pollen tube​

Answer 1

Angiosperm male gametophytes have two haploid nuclei (the germ nucleus and tube nucleus) contained within the exine of the pollen grain (or microspore). Female gametophytes of flowering plants develop within the ovule (megaspore) contained within an ovary at the base of the pistil of the flower.

Answer 2

The cell in the male gametophyte of angiosperms which produces Pollen tube are the angiosperm which contain two haploid nuclei (the germ nucleus and tube nucleus) within the exine of the pollen grain (or microspore). Whereas female gametophytes of flowering plants are formed within the ovule (megaspore) in an ovary at the base of the pistil of the flower.

Explanation:

• A pollen tube holds a tube-like composition produced by the male gametophyte of seed plants after the germination process.

• Pollen tube expansion for a chief stage in the plant life cycle.

• The functions of the pollen tube is to act as a conduit to transfer the male cells from the pollen grain either from the stigma (in flowering plants) to the ovules at the base of the pistil or directly through ovule tissue in some gymnosperms.

• In the 19th century, Giovanni Battista Amici discovered pollen tubes.

• It can be taken as a model to understand the plant cell behavior.
