How many meiotic divisions are required to produce 480 seeds?

Question

Answer

600( 480+ 120)

Answer

Meiotic Divisions Required to Produce 480 Seeds

Meiosis is the process of cell division that occurs in sexually reproducing organisms. It results in the formation of gametes, which are haploid cells that have half the number of chromosomes as the parent cell. In plants, meiosis occurs in the reproductive organs, such as the flowers, and is essential for the formation of seeds.

Meiosis and Seed Production

The process of seed production involves the fusion of male and female gametes, which results in the formation of a zygote. The zygote then undergoes cell division and differentiation to form an embryo, which eventually develops into a mature seed. In plants, meiosis is required to produce the male and female gametes that will fuse during fertilization.

Number of Meiotic Divisions Required

In plants, meiosis results in the formation of four haploid cells from a single diploid cell. Therefore, to produce 480 seeds, the number of meiotic divisions required will depend on the number of haploid cells required to form a single seed.

For example, if each seed requires two haploid cells (one from the male parent and one from the female parent), then a total of 960 haploid cells will be required to produce 480 seeds. Since each meiotic division results in the formation of four haploid cells, a total of 240 meiotic divisions will be required to produce the required number of haploid cells.

Conclusion

The number of meiotic divisions required to produce 480 seeds will depend on the number of haploid cells required to form a single seed. In plants, meiosis is required to produce the male and female gametes that will fuse during fertilization, resulting in the formation of a zygote that will eventually develop into a mature seed.

Answer

I think 120 meiotic divisions are requirec

Answer

One seed will be formed from one sperm and one egg. Thus,we need 480 eggs and so it will have 480 meiotic divisions and we need 480 sperms from the 120 meiotic divisions ( one pollen mother cell produces 4 pollen grains from 1 meiotic division).

Answer

480 for female gametophyte I.e egg cell
+ 120 from male side (1 meiosis = 4 pollen grain for 4seeds so for 480 seed 120 meiosis are required so total =600

Answer

As one meiotic division produces one egg so to produce 480 seeds it needs 480 meiotic division to produce 480 eggs and this 480 eggs has to fuse with 480 male gamate, as one meiotic division gives 4 male gametes so 120 will give 480. Total is (480+120)=600meiotic division gives rise to 480 seeds
