What is a cell ? how many types of cells are there?​

Cell is the living blocks of life. They form the structural

and the functional unit of our life, that is a group of cell

forms tissue, a group of tissue forms organ, a group of

organs form organ system and finally a group of organ

systems form a complete organism / individual.

And there are two types of cell

1/ eukaryotic cell ( consists of the plant cell and the animal

cell )

2/ prokaryotic cell (... I don't know man )

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
