The best material for the study of mitosis in the laboratory is a/an:
Correct answer: B. Root tip
- A. Anther
- B. Root tip
- C. Animal tissues
- D. Ovary
Explanation
Mitosis occurs both in somatic cells as well as in germ cells of the gonads. In plants, mitosis occurs in the meristematic cells of the root tip or shoot tip. These cells divide at a faster rate. So the root tip shows active cell division and is used in the laboratory to study mitosis. For studying meiosis, young anthers are used.

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.
