1 meiotic division ----------- 4 male gametes
?. meiotic division------------1000 male gametes..
=1000/4=250

Answer:

Number of Meiotic Divisions to Produce 1000 Male Gametes in a Flowering Plant: 4

Explanation:

- Meiosis is a process of cell division that produces haploid cells, such as gametes.
- In a flowering plant, meiosis occurs in the anthers of the flower, which are the male reproductive structures.
- Meiosis involves two rounds of cell division: meiosis I and meiosis II.
- In meiosis I, the homologous chromosomes pair up and exchange genetic material through crossing over. Then, they separate into two daughter cells, each containing one set of chromosomes.
- In meiosis II, the sister chromatids of each chromosome separate into four haploid daughter cells.
- Therefore, each meiotic division produces two haploid daughter cells.
- To produce 1000 male gametes, four meiotic divisions are required, as follows:

- Meiosis I: 2 cells
- Meiosis II: 4 cells
- Meiosis II: 8 cells
- Meiosis II: 16 cells
- Meiosis II: 32 cells
- Meiosis II: 64 cells
- Meiosis II: 128 cells
- Meiosis II: 256 cells
- Meiosis II: 512 cells
- Meiosis II: 1000 cells

- Therefore, it takes four meiotic divisions to produce 1000 male gametes in a flowering plant.
