Question

State difference between microsporogenesis and megasporogenesis?


class 12th CBSE Biology sample paper

Answer 1

Microsporogenesis:

1) In this process, haploid microspores are formed from diploid microspore mother cell by meiosis division.

2)It occurs in pollen chamber of anther

3)Microspore are generally arranged n tetrahedral tetrad after meiotic division,

4)All four microspore are tetrad and functional

Megasporogenesis :

1) In this event, haploid megaspore ( embryo-sac) is formed from diploid megaspore mother cell.

2) It takes place inside the nucleus of ovule.

3) The megaspore are commonly arranged in linear tetrad after meiosis.

4) Only one megaspore of a tetrad becomes functional to form embryo-sac.

Answer 2

ANSWER
......
Micro sporogenesis:
1. IT IS THE FORMATION OF THE HYPOTHETICAL MICROSCOPE TO THE DIPLOID MICROSCOPE....

2. MICRO SPOROGENESIS IS FOUND INSIDE MICROSPORANGIUM.


Mega sporogensis:

1. . IT IS MEIOTIC FORMATION OF HAPLOID MEGA SPORES FROM DIPLOID MEGASPOROGENESIS MOTHER CELL.

2. IT IS FOUND INSIDE A MEGA SPORANGIUM.
