Question

Give reasons for the following:
(a) The cell is called the structural and functional unit of life.
(b) Plant cells are more rigid than the animal cells. dav answer​

Answer 1

• Cells are called the structural and functional unit of life because all the living organisms are made up of cells and also all the functions taking place inside the body of organisms are performed by cells. ... So, cell is the basic structural unit for all unicellular and multicellular organisms.
• The plant cells are more rigid compared to animal cells as they have cell wall. ... Similarly, when excess water enters cell, the plant cell swells but it do not burst due to presence of wall pressure....☺️❣️

Answer 2

Answer:

a)A cell is capable of carrying out all the life functions, such as nutrition, excretion, respiration, etc. Hence a cell is called the functional unit of life. The cell is the smallest unit of life and all the living beings are made up of cells. Hence a cell is called the structural unit of life.

b)The plant cells are more rigid compared to animal cells as they have cell wall. It provides rigidity as well as protection from outer environment. ... Similarly, when excess water enters cell, the plant cell swells but it do not burst due to presence of wall pressure
