8 ➡ Characteristics of PROKARYOTES are as follows :-
they are unicellular
they donot have a well DEFINED nucleus.
they have freely floating dna.
usually their size is less than a nanometer.
The absence of nucleolus and mitotic apparatus.

9 ➡ Multicellular organisms are made up of millions and trillions of cells. All these cells perform specific functions. All the cells specialised for PERFORMING similar functions are grouped together as tissues in the body. Hence, a particular function is carried out by a group of cells at a definite place in the body. Similarly, different functions are carried out by different groups of cells in an organism. This is known as DIVISION of labour in multicellular organisms.

10 ➡ Cell is the basic structural and functional unit of an organism as in unicellular organism a single cell is able to perform all the functions like respiration, excretion etc..
