Question

how is cell division responsible for growth?

Answer 1

mitosisOne cell gives rise to two genetically identical daughter cells during the process of mitosis. Encyclopædia Britannica, Inc. Most tissues of the bodygrow by increasing their cellnumber, but this growth is highly regulated to maintain a balance between different tissues.

Answer 2

Cell division is responsible for growth because in unicellular organisms, it is the basis of reproduction and in multi-cellular organisms it forms the basis of tissue growth and maintenance.

EXPLANATION:

Tissues of the body will grow by 'increasing' their 'cell number' but this growth is regulated to maintain a 'balance' of the 'growth' of the tissues. 'Cell division' is the process in which a 'cell' divides into 'two' or more cells.

This process is known as mitosis that allows for continuous construction and repair of the cells of the body thereby facilitating growth.
