Ribosomes are essential for protein synthesis, but they are present in Mitochondria and plastids, the sites of respiration and photosynthesis. What is the role of ribosomes in these cell organelles
1 Ribosomes transport ATP formed in Respiration and photosytnesis to cytoplasm through E.R.
2 Sub units of some required proteins are synthesised in these organelles
3 Ribosomes transpors RNA and DNA to cytoplasm
4 All the above are correct
Explanation:
Exp:B Ribosomes are known as protein factory \& contains large Riboncleoprotein consisting of RNA\& Protein that translate mRNA into polypeptides. Ribosome contains rRNA and r-proteins which are termed as large subunit or small subunit.

Microtubule is involved in the
1 cell division
2 DNA recognition
3 muscle contraction
4 membrane architecture
Explanation:
Exp:A Microtubules are made of alpha and beta tubulin protein that bind together to form chain called protofilament. 13-Protofilament arrange into a cylindrical pattern to form a microtubule. Microtubules main function is - cell movement cell division, cell transport.

The primary function of intermediate filament is
1 generate movement
2 provide mechanical stability
3 transport organelles within the cell
4 stabilize microtubules against disassembly
Explanation:
Exp:B The primary function of intermediate filament is provide mechanical stability. It contrast actin filament and micro tubules.
