Question

wrong explain how organisms actually grow.

Answer 1

Answer:

See the answer below

Explanation:

Jimmy was right to say organisms grow because their cells grow.

The growth of organisms can happen in terms of an increase in the number of cells they have (through mitotic cell division) or an increase in the volume of the cells with or without an increase in the number of cells.

A good example is found in plants, most of which undergo an increase in size without any increase in the number of cells in their bodies. The uptake and storage of water in the vacuole produces a pressure that pushes on the cell walls, causing an increase in length, girths, and other growth features of the cells of plants.
