Question

If the no of chromosomes in an organism is 16 then what is the no of chromoaomes of endosperm and microspore mothwr cell

Answer 1

1.In case of gymnosperms :

Endosperm-8 chromosomes bcz it is haploid.

2.Microspore Mother Cell -16 chromosomes as it is a part of diploid sporophyte.

In case of angiosperms :

1.Endosperm-24 chromosomes bcz one haploid male gamete (8 chromosome) and two haploid polar nuclei (8 chromosomes each) fuse to form the endosperm.

8+8+8=24

2. Microspore mother cell - 16 chromosomes as it belongs to the diploid sporophyte...

I hope I could give you my best

Answer 2

Answer:

Explanation:

About 70% of angiosperm species have endosperm cells that are polyploid. These are typically triploid (containing three sets of chromosomes), but can vary widely from diploid (2n) to 15n
