What is the ploidy of Nucellus MMC?

2n
The ploidy level of the plant is diploid. Hence, the ploidy level of nucellus is 2n. MMC is a microspore mother cell, also known as meiocyte which undergoes meiotic division and produces female gametes. So, it’s ploidy is 2n.

What is the ploidy of megaspore mother cell and female gametophyte?

A megaspore mother cell is a diploid cell in which meiosis occurs, resulting in the production of four haploid megaspores. Hence, Ploidy level of Nucellus, endosperm, polar nuclei, Megaspore mother cell, female gametophyte respectively are 2n,3n,n,2n,n. So, the correct answer is ‘2n,3n,n,2n,n’.

What is the ploidy level of cells of the Nucellus megaspore mother cell polar nuclei and male gametophyte in an angiosperm?

diploid 2n
Nucellus is the central part of ovule and it is diploid 2n. Polar nuclei os present in the embryo and is haploid, two polar nuclei (n+n) and a male gamete (n) fuse to form endosperm which is triploid (3n).

What is ploidy of megaspore?

Its ploidy is 2n. MMC (produces haploid gametophytes by meiotic division) Since, it undergoes meiotic division its ploidy is 2n. Female gametophytes also called as embryo sac (produced by meiotic division from Megaspore mother cell) has ploidy n. Similarly, the functional megaspore is haploid in nature.

What is the ploidy of the gametophyte?

The gametophyte is a haploid (n), gamete-producing plant.

Is Nucellus diploid or haploid?

Nucellus(located within the integumentary) have 2n ploidy. The functional megaspore is haploid in nature.

What is the ploidy of cells of Nucellus?

2n ploidy
Nucellus(located within the integumentary) have 2n ploidy. The functional megaspore is haploid in nature.

What is the ploidy of Microspore tetrad?

haploid
MMC may be a diploid cell that undergoes meiosis to make four haploid microspores which are arranged during a tetrad. This process is understood as microsporogenesis. Each of those four microspores are found to be developed into a pollen grain. This tells us that the ploidy of microspore tetrad cells is haploid.

Is Microspore diploid or haploid?

Microspores are haploid, and are produced from diploid microsporocytes by meiosis.

What is the ploidy of tetrad and Nucellus?

Meiosis1 occurs in the microspore mother cell which produces 2 diploid cells. After the meiosis2 the number of cells becomes four. The ploidy of each cell in a tetrad happens to have a ploidy ‘n’ as they are produced by the meiotic division. So the answer is: the ploidy of the cell of the tetrad is haploidy.

Is microspore diploid or haploid?
