How many male gametes are involved in the production of 100 seeds?

For formation of 100 zygotes, 100 male gametes and 100 female gametes (eggs) are required. 100 male gametes are developed from 100 microspores (from 25 meiotic divisions) and 100 eggs are developed from 100 megaspores (from 100 meiotic division).

How many male gametes would produce 200 viable seeds?

(d) The number of male gametes involved in seed formation would be 200 as each male gamete will fuse with 1 egg nuclei to form zygote, which will further give rise to the seed.

How many male gametes are involved in this case?

(v) How many male gametes were involved in this case? The number of male gametes involved would be 240. Each male gamete fuses with one egg nuclei to form a zygote that gives rise to seed.

How many meiotic divisions are required for the formation of 200 male gametes in a typical angiosperm?

Now, 1 meiotic division in male produces 4 gametes. So, in order to make 200 male gametes, there will be 50 meiotic divisions in male. In total there are 200+50=250 meiotic divisions required to produce 200 seeds.

What is male gametophyte?

Male Gametophyte: Plants show alternation of generation, which alternate between the diploid sporophyte and the haploid gametophyte. ... A mature male gametophyte in angiosperms is a pollen grain that comprises a 3-celled structure, while a female gametophyte is an embryo sac which is a 7-celled structure.

How many and what type of male gametes are produced by the male gametophyte of capsella?

Androgenic haploids are produced by young pollen grains because rest all are the diploid tissue. This discussion on How many and what type of male gametes are produced by the male gametophyte of Capsella -a)One,.

How many pollen grains and gametes are involved in the production of 200 viable seeds in a capsicum fruit?

(b) (i) Number of pollen grains required to form 200 seeds will be 200 only as each pollen grain carries to generative cells or male gametes and only one of the two are involved in zygote formation.

How many gametes are required to produce one seed in an angiosperm?

The angiosperm male gametophyte is composed of one tube cell and one generative cell. To form two male gametes, this generative cell divides. Thus the male gametophyte angiosperm is 3-celled.

How many gametes are needed for seed?

The formation of the male gamete requires only one meiotic division which results in four male gametes while the formation of four female gametes requires four meiotic divisions. So, the five meiotic divisions result in four seeds thus 500 meiotic divisions result in 400 seeds.

How many male Gametophytes do single mother cells?

Thus, a pollen mother cell generates four gametes.

How many male Gametophytes does a single microspore mother cell produce?

As each microspore forms one male gametophyte, hence , 1600 male gametophytes can be produced.

How many male gametes are involved in the formation of 360 seeds?

(c) The minimum number of pollen grains to land under the pollination stigma is 360 and there are two male gametes in each pollen grain. One fuses with polar nuclei and forms endosperm from these two gametes, while the other male gamete fuses with the egg cell to create the zygote that finally gives birth to the seeds.

How many pollen grain mother cells are required for the formation of 200 male gametes?

250 meiotic divisions are required for the formation of 200 seeds of Capsella.

How many meiotic divisions are required to produce 100 seeds tomatoes?

So, for the development of 100 megaspores 100 meiotic division is required. - So, by the fusion of 100 microspores and 100 megaspores, 100 seeds are formed. - Hence for the 100 seed production 200 meiotic division takes place in the Cyperaceae family. Hence, the correct answer is option (D).

How many meiotic division would be required to produce 101 female Gametophytes in an angiosperm A 101 B 26 C 127 D none of these?

Thus, one meiotic division produces one matured female gametophyte in an angiosperm. Hence, 101 meiotic divisions are required to produce 101 female gametophytes in an angiosperm.
