Question: How many chromosomes are present in functional megaspore?

How many chromosomes are present in the functional megaspore of Aleurone?

What would be number of chromosomes in the cells of aleurone layer in plant species have 8 chromosomes in its synergids.

How many functional megaspore are there?

Out of the four megaspores, three degenerate and one functional megaspore develops into the embryo sac, i.e. female gametophyte.

How many chromosomes are present in the functional megaspore if aleurone layer cell of a cereal consists of 36 chromosomes?

Explanation: Megaspore mother cell is diploid in nature. In this way, if 2n= 10, the quantity of chromosomes in aleurone layer will be triploid in nature. The quantity of chromosomes is in this way, 3n = 15.

What is functional megaspore?

The functional megaspore in angiosperm develops into an embryo sac. … The cell undergoes meiosis and results in the formation of 4 haploid megaspore nuclei. Megagametogenesis is the process by which the embryo sac is formed. The embryo sac typically has eight nuclei in them.

Is a megaspore 1n or 2n?

The gametophytes (1n), microspores and megaspores, are reduced in size. This phase may take more than one year between pollination and fertilization while the pollen tube grows towards the megasporocyte (2n), which undergoes meiosis into megaspores. The megaspores will mature into eggs (1n).

Is megaspore diploid or haploid?

A megaspore mother cell, or megasporocyte, is a diploid cell in plants in which meiosis will occur, resulting in the production of four haploid megaspores.

What is the number of chromosomes in endosperm layer of megaspore mother cell contains 10 chromosome?

Aleurone is the outermost layer of the endosperm. The endosperm is a triploid tissue and if the megaspore mother cell which are diploid have 10 no. of chromosomes then the no. of chromosomes in the aleurone layer will be 15 .

How many megaspore remain functional in each ovule of the Spermatophytes?

In most flowering plants, only one megaspore survives per ovule, typically this is the most proximal megaspore, while the remaining three undergo programmed cell death (Fig. 13.2A). The surviving megaspore is called the Functional Megaspore (FM) and it gives rise to the embryo sac after mitotic divisions (see below).

How many divisions occur in functional megaspore and which type of division and how many nuclei are formed in female gametophyte?

Functional megaspore represents the first cell of the female gametophyte. Mostly chalazal and grows along the micropylar- chalazal axis. The nucleus undergoes three mitotic divisions and form eight nuclei.

How many megaspore remain functional in allium?

Out of four megaspores, only one which remains towards the chalazal end behaves as functional megaspore and the other three which remain towards the micropylar end, gradually degenerate (Fig.

What would be the number of chromosomes of Aleurone cells of a plant with 42 chromosomes in its root tip cells?

Since the cells of aleurone layer are triploid, the number of chromosomes would be = 63, as root tip cells (2n) has 42 chromosomes.

What would be the number of chromosomes of the cells of a plant with 42 chromosomes in its root tip cells?

Since, the cells of aleurone layer are triploid, the number of chromosomes woud be 63 as root tip cells. (2n) has 42 chromosomes.
