Chondriosome was discovered by
1 Benda
2 Sutton
3 Tatum
4 Palade
Explanation:
Exp:A Chondriosome were discovered by Benda in 1888 , as it is resembled with cartilage hence it is termed as chondriosome. - Sutton- discovered chromosomes in 1902. - Tatum- discovered genes in 1941. - Palade- discovered the endoplasmic reticulum in 1955.

Which of the following structures is found on the inner surface of the inner mitochondrial membrane?
1 Microsome
2 Oxysome
3 Sub-unit of Parson
4 Quantasome
Explanation:
Exp:B Oxysome structures is found on the inner surface of the inner mitochondrial membrane. They are also called - \(F_{1}\) Particles or ATP syntheses. They play important role in the formation of energy for the functioning of the cell. - Microsome : It is a heterogeneous set of vesicular 20-200 nm in diameter and formed from the endoplasmic reticulum when cells are distrupted. - Quantasome : It is particle found in the thylakoid membrane of chloroplasts in which photosynthesis takes place. - Sub-unit of Parson-Stalk less mitochondrial particles present on outer membrane.

Choose the incorrect about mitochondria -
1 Has \(80 \mathrm{~S}\) ribosome
2 Naked circular DNA
3 ETS on inner mitochondrial membrane
4 Power house of the cell
Explanation:
Exp:A Mitochondria have single circular naked DNA molecule along with lots of ribosomes. These ribosomes are 70S type, which are further involved in mitochondrial protein synthesis, so the option (a) is incorrect about mitochondria.

Protein molecules that form huge pores in the membranes of the plastids, mitochondria and some bacteria are called as
1 Stomata
2 Porins
3 Coherin
4 Subarins
Explanation:
Exp:B The porins are proteins that form huge pore in the outer membrane of mitochondria, plastids and some bacteria. These act as channels to specific substance. - Subarins is chiefly deposited in the cell of cark. - Stomata are tiny pores through which plants breathe. They are found on the upper and lower side of leaves, on flower, petals and stem. - Coherin is a peptide isolated from the bovine posterior pituitary gland.
