Answer 1

Answer:

Explanation:

A cell is defined as the most basic, structural and functional unit of all living organisms. Essentially, a cell is a structure that contains organelles which provide necessary functions to sustain itself. However, not all cells are the same.

Plants have cells that are vastly different from animals. One of the primary differences between the two is the absence of cell walls in animal cells. Cells also vary in size, with the largest one in the human body being the egg or the female ovum. It measures roughly around 1 millimetre across. The smallest cell is the granule cell which is found in the human cerebellum, measuring roughly around 4.5 micrometres in size.
