The number chromosomes in germ cells is:
Correct answer: C. Haploid
- A. Tetraploid
- B. Triploid
- C. Haploid
- D. Diploid
Explanation
Germ cells are products of meiosis, a process that reduces the chromosome number by half, resulting in haploid cells. This is essential for maintaining the species' chromosome number through sexual reproduction. Haploid cells carry one set of chromosomes, so during fertilization, the fusion of two haploid cells restores the diploid state. In contrast, tetraploid and triploid chromosome numbers are abnormal in the context of germ cells, while diploid refers to somatic cells, which have two sets of chromosomes.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
