Question

multiple choice question
which occurs during meiosis?

one haploid cell divides and makes four diploid cells.
one haploid cell divides and makes two diploid cells.
one diploid cell divides and makes two haploid cells.
one diploid cell divides and make four haploid cells.

Explanation:

Meiosis is a cell division process where a diploid cell (with two sets of chromosomes) undergoes two rounds of division. In the end, it produces four haploid cells (each with one set of chromosomes), which are used in sexual reproduction (like gametes: sperm or egg cells). Let's analyze each option:

• First option: Meiosis starts with a diploid cell, not haploid, and produces haploid cells, not diploid. Eliminate.
• Second option: Meiosis starts with diploid, and the end result is four cells, not two diploid. Eliminate.
• Third option: Meiosis has two divisions. The first division of a diploid cell gives two haploid cells, but then those divide again. The final result is four haploid cells, so this describes only the first division, not the full meiosis process. Eliminate.
• Fourth option: Correctly describes meiosis: one diploid cell undergoes two rounds of division to produce four haploid cells.

Answer:

D. One diploid cell divides and make four haploid cells. (Note: There's a typo in the option, it should be "makes" instead of "make", but it's the correct description of meiosis.)
