QUESTION 5
Choose the statement which best describes a bacterial vegetative cell.
The vegetative cell is a metabolically active, growing cell.
The vegetative cell is a dormant, metabolically inactive structure that is resistant to harsh environmental conditions.
The vegetative cell can survive in conditions of extreme heat and low nutrient availability.
The vegetative cell cannot grow or replicate.
All of the above
QUESTION 7
Which of the following is NOT true about viruses?
Viruses exist as viral particles, not as living cells.
Viruses are prokaryotes.
Viruses can infect bacteria.
Viruses are obligate parasites

Which of the following is NOT true about viruses?
A.Viruses exist as viral particles, not as living cells.
B.Viruses are prokaryotes.
C.Viruses can infect bacteria.
D.Viruses are obligate parasites
Explanation / Answer
1.
A vegetative cell is the metabolically active living cell that is capable of feeding, reproduction, etc. It is the active metabolising stage of the cell as opposed to the inactive dormant stage, which is often termed as the spore.
This shows that option A) The vegetative cell is a metabolically active, growing cell, is the right choice.
Since, all the other options are referring to the status of the cell in a dormant spore stage, option b, c, and d, cannot be the right choice.
2.
Viruses are not considered as living organisms and hence, they cannot be termed as prokaryotes. They thrive outside the living cell as inanimate particles and are considred to be obligate parasites capable of infecting bacteria.
This shows that option (B) Viruses are prokaryotes, should be the right option.
