Question

A growing organism, such as a human embryo, uses cell division to increase the size and specialization of individual organs. However, mature organisms, like a retired adult human, do not use cell division to maintain and repair body tissue.

A) True .
B) False.

Answer 1

A growing organism, such as a human embryo, uses cell division to increase the size and specialization of individual organs.

Step-by-step explanation:

A human, as well as every sexually reproducing organism, begins life as a fertilized egg (embryo) or zygote. Trillions of cell divisions subsequently occur in a controlled manner to produce a complex, multicellular human. Once a being is fully grown, cell reproduction is still necessary to repair or regenerate tissues. For example, new blood and skin cells are constantly being produced. All multicellular organisms use cell division for growth, maintenance, and repair of tissues. Single-celled organisms use cell division as their method of reproduction.
