QUESTION: 1

Main difference between animal and plant cell

A.
Nutrition
B.
Growth
C.
Respiration
D.
All of above

Solution:

The plant cell and animal cells are different as per growth, nutrition and respiration.

Other than that, there is the difference in the cell wall, chloroplasts and vacuoles.

However, there are many similarities in the cells such as both of them are eukaryotic cells that contain membrane-bound such as mitochondria, nucleus, Golgi apparatus, lysosomes, etc.

QUESTION: 2

Plasmolysis occurs due to

A.
Absorption
B.
Endosmosis
C.
Osmosis
D.
Exosmosis

Solution: Exosmosis. noun. The passage of a fluid through a semipermeable membrane toward a solution of lower concentration, especially the passage of water through a cell membrane into the surrounding medium.Plasmolysis is the process in which cells lose water in a hypertonic solution. The reverse process, cytolysis, can occur if the cell is in a hypotonic solution resulting in a lower external osmotic pressure and a net flow of water into the cell.

QUESTION: 3

A cell placed in hypotonic solution will

A.
Shrink
B.
Show plasmolysis
C.
Swell up
D.
No change

Solution: A hypotonic solution consists of more amount of solvent and less amount of solute in it. Water is free to move in and out of the cell through a process called osmosis. But in this case more amount of water will enter the cell than leave. Hence, the cell will swell up. Therefore, option (C) is correct.

QUESTION: 4

Aleuroplasts in a cell store

A.
Starch
B.
Matrix
C.
Protein
D.
Nutrients

Solution:

QUESTION: 5

Well defined nucleus is absent in

A.
Plant cell
B.
Animal cell
C.
Prokaryotic cell
D.
Eukaryotic cell

Solution: Blue-green algae or cyanobacteria is a prokaryotic organism, i.e., it lacks well defined nucleus, whereas diatoms, algae and yeast all are eukaryotic organism, i.e., they show the presence of true nucleus and cell membrane bound organelles.
