Question 1 of 15beginner🧠 RememberVery Short2 marks

Name the parts of an angiosperm flower in which development of male and female gametophyte take place.

Correct Answer

Male gametophyte: The development of the male gametophyte (pollen grains) takes place inside the microsporangium (pollen sac) located in the anther of the stamen. The sporogenous tissue in the microsporangium undergoes meiosis to form microspores, which mature into pollen grains.

Female gametophyte: The development of the female gametophyte (embryo sac) takes place in the ovule (megasporangium) present inside the ovary of the pistil. The functional megaspore develops into the embryo sac through monosporic development.

Explanation

According to NCERT Chapter 1 'Sexual Reproduction in Flowering Plants', the male gametophyte (pollen grains) develops in the microsporangia of the anther, while the female gametophyte (embryo sac) develops in the ovule (megasporangium) located inside the ovary. This question tests the student's understanding of the sites of gametophyte development in angiosperms.

Solution Steps

  1. Step 1: Identify that pollen grains (male gametophyte) develop in microsporangia within the anther.

  2. Step 2: Identify that embryo sac (female gametophyte) develops from functional megaspore in the ovule inside the ovary.
