Question

give reason for the following (a) the cell is called structural and functional unit of life(b) Plant cell and more bigger than the animal cell​

Answer 1

Answer:

A) Cell is called structural unit because body of all the organisms is made up of cells. It is functional unit of life because all the functions of body (physiological, biochemical. genetic and other functions) are carried out by cells

B)Plant cells can be larger than animal cells. The normal range for an animal cell varies from 10 to 30 micrometers while that for a plant cell stretches from 10 to 100 micrometers. Beyond size, the main structural differences between plant and animal cells lie in a few additional structures found in plant cells.

Answer 2

1. the cell is called structural and functional unit of life because it carries all the work related to metabolism . No other component smaller than cell like cell organelles for example mitochondria endoplasmic reticulum or any other cannot function outside the cellular boundary hence cell is the functional and structural units of life .
2. plant cells are bigger than animal cells because they contains vacuoles mainly SAP vacuoles .
