How many mitotic divisions are needed to form 100 seeds?
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 mitotic divisions are required to produce 200 seeds?
Thus 5 meiotic divisions are needed for the formation of 4 seeds and 250 meiotic divisions are required fro the formation of 200 seeds.
How many mitotic divisions are required to produce 50 seeds?
Thus the correct answer is option ‘A’ which is 63 meiotic divisions.
How many mitotic divisions are required to produce 120 seeds?
1 meiotic division refers to the formation of 4 microspores from one microspore mother cell. Each microspore develops into a pollen grain( male gamete). So, for getting 120 male gametes, we require= 120/4 = 30 meiotic divisions.
How many mitotic divisions are required to produce a seed?
Answer: 200 mitotic divisions are required in microspores In the formation of 200 male gametes and 100 seeds.
How many meiotic divisions are needed for formation 100 grains of wheat?
So, for the formation of 100 grains of wheat, a total of 100 female gametes are needed, which means a total of 100 meiotic divisions are needed. Hence, including the number of meiotic divisions in both the male and female sex organs of the plant, a total of 125 divisions would give rise to 100 wheat grains.
How many mitotic divisions are required to form 400 seeds?
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 members are required to make 200 seeds?
In total there are 200+50=250 meiotic divisions required to produce 200 seeds.
How many mitotic divisions are required?
Therefore, 7 mitotic divisions are required for a single cell to make 128 cells.
How many meiotic divisions are required to produce 52 seeds?
In spermatogenesis, 52 sperm can be produced in 13 meiotic divisions.
How many meiotic divisions are required to produce 60 seeds?
How many meiotic divisions are necessary for the formation of 60 seeds of wheat? Seed is a product of fusion of a male and a female gamete. Hence 100+25=125 meiotic divisions are needed.
How are mitotic divisions calculated?
In mitosis one cell divides in two and both daughter cells have identical sets of chromosomes to the parent cell. 8. Formula of mitosis: (2n × 2) / 2.
How many meiotic divisions are required for the formation of 100 functional pollen grains and 100 functional Megaspores respectively?
So, only 25 meiotic division is required for 100 megaspores. But, for 100 functional megaspores, 100 meiotic divisions are required.
How many meiotic and mitotic divisions are required for the development of 100 male gametophytes in angiosperms?
Hence, one meiotic division and two mitotic division are required for the formation of fully mature male gametophyte from microspore mother cell in angiosperm.
How many Meiosiss are needed for 100 male gamete formation?
Hint: To produce 100 male gametes, 25 meiotic divisions are done, and to produce 100 female gametes, 100 meiotic divisions are done.
