Answer:
The endoplasmic reticulum is a network of canals and sacs made of cell membrane. There are two types of this structure: the Rough endoplasmic reticulum and the smooth endoplasmic reticulum.
Step-by-step explanation:
- Endoplasmic reticulum is an irregular network of double membrane distributed over the entire cytoplasm of the cell.
- It establishes connection between the cell membrane and the nuclear membrane.
- Endoplasmic reticulum is classified into two types depending on the presence and absence of ribosome on its surface.
- If ribosome are present on it surface then it is called rough endoplasmic reticulum and if ribosomes are absent on its surface then it is called smooth endoplasmic reticulum.
- Endoplasmic reticulum functions producing, processing and transporting biochemical compounds like protein and lipids. It also forms the supporting framework of the cell.
