Which one of the following statements is correct ?
Updated On: Jul 11, 2024
- Tapetum nourishes the developing pollen
- Hard outer layer of pollen is called intine
- Sporogenous tissue is haploid
- Endothecium produces the micorspores
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
The tapetum is the innermost layer of microsporangium. It nourishes the pollen grains. The inner wall of the pollen grain is called intine. Endothecium is the wall around the microsporangium, which provide protection and help in dehiscence of anther to release the pollen. The sporogenous tissue is diploid. It undergoes meiotic division to form microspore tetrads.

Sexual Reproduction in Flowering Plants
Sexual reproduction in flowering plants takes place or happens when the production of a new organism occurs from two parents by making use of their gametes or sex cells. Both sexual and asexual reproduction can be found in plants. Nearly all flowering plants reproduce sexually. Flowers play a captious role in the process as it carries both the male and female reproductive parts commonly known as androecium and gynoecium respectively.
An individual flower comprises the following parts -
- Pedicle
- Calyx
- Petals
- Sepals
- Stamen
- Pistil
- Receptacle
