Question

Compare different cell organelles and their functions and explain there similarities and difference

Answer 1

Answer:

The difference between rough endoplasmic reticulum & smooth endoplasmic reticulum is :

1) Rough endoplasmic reticulum

• The rough endoplasmic reticulum looks rough under microscope because it has particles called ribosomes on its surface.
• That ribosome are manufacturing site of proteins for cells.
• The rough endoplasmic reticulum is present around the nucleus.

2) Smooth endoplasmic reticulum

• The smooth endoplasmic RETICULUM (SER) looks smooth under microscope because they don't have ribosomes.
• The SER help in manufacturing of fat molecules or lipids which are important for cell function.
• These proteins & lipids help in building cell membrane. This process of building cell membrane is called membrane biogenesis.

Explanation:

The similarities between rough endoplasmic reticulum & smooth endoplasmic reticulum is :

1. They both are channels for transport of material ( especially proteins) between various regions of cytoplasm & the nucleus.
2. They also function as cytoplasmic framework providing surface for some biochemical activities of cell.
