Which of the following can appropriately be said as `the basic unit of life`?

A
Protoplasm

A
Cellulose

B
Globulin

C
Lipids

D
Xanthocyanin
Question 18
1 / -0

Which of the following term describes the undefined region of the nucleus in prokaryotes?

A
Nucleoid

B
Nuclear wall

C
DNA

D
RNA

Solution

The undefined nuclear region of prokaryotes is also known as the nucleoid. Prokaryotes do not contain proper cell organelles, and hence the nuclear material is just accumulated indefinitely in a region known as the nucleoid. A Prokaryotic cell is primitive in the organisation.
Question 19
1 / -0

Which of the following organelles is known as the power house of a cell?

A
Mitochondria

B
Ribosomes

C
Cytoplasm

D
Golgi bodies

Solution

The powerhouse of the cell, mitochondria play host to one of the most important processes in your body, cellular respiration. Taking in glucose and oxygen, mitochondria produce energy, which they capture and package as energy-rich molecules of ATP.
