Organelles are the chemical factories in the cell these organelles are mostly present in the cytoplasm of the cell
These organelles do movement with the cytoplasm

1) E.R (endoplasmic reteculum)
These are the tube like structure present in the cytoplasm these tubes lay down from the nuclear membrane to the end of cell membrane
There are two types of (E.R)
1) rough E.R
2) smooth E.R

Tomorrow we shall clerify the both types of E.R and it's function

In text topic I shall tell you about organelles so you should have focus on your study

There are two types of cell
1) prokaryotic cell
2) eukaryotic cell

Prokaryotic cell..
These are the cells which are called not true cells because these have not a complete system of organelles and these types of cell have not present a nuclear membrane
Ex. Bacterial cell

Eukaryotic cell..
These cells are called true cells because these cells have complete system of organelles and nuclear membrane is also present to it's nucleus
