Question

Meosis occurs only during reproduction....If cell division can be considered as reproduction, why do the cells divide by mitosis??

Answer 1

Answer:

Because the chromosome number of a species remains the same from one generation to the next, the chromosome number of germ cells must be reduced by half during meiosis. To accomplish this feat, meiosis, unlike mitosis, involves a single round of DNA replication followed by two rounds of cell division

Answer 2

Explanation:

HEY MATE ........

➡️MITOSIS USUALLY RESULTS IN THE PRODUCTION OF DIPLOID DAUGHTER CELLS WITH IDENTICAL GENETIC COMPLEMENT .

➡️THE GROWTH OF MULTICELLULAR ORGANISMS IS DUE TO MITOSIS.

➡️ CELL GROWTH RESULTS IN DISTURBING THE RATIO BETWEEN THE NUCLEUS AND CYTOPLASM IT THEREFORE BECOMES ESSENTIAL FOR THE CELL TO DIVIDE TO RESTORE THE NUCLE- CYTOPLASMIC RATIO.

➡️ A VERY SIGNIFICANT CONTRIBUTION OF MITOSIS IS CELL REPAIR .

➡️THE CELLS OF THE UPPER LAYER OF THE EPIDERMIS , CELLS OF THE LINING OF THE GUT AND BLOOD CELLS ARE BEING CONSTANTLY REPLACED .

➡️MITOSIS DIVISIONS IN THE MERISTEMATIC TISSUES - THE APICAL AND THE LATERAL CAMBIUM RESULT IN A CONTINUOUS GROWTH OF PLANTS THROUGHOUT THEIR LIFE.
