Question 2
1 / -0

Directions : In the following question, the Assertions (A) and Reason (R) have been put forward. Read both the statements and choose the correct option from the following.
Assertion : Nucleolus is smaller in actively working cell.

Directions : In the following question, the Assertions (A) and Reason (R) have been put forward. Read both the statements and choose the correct option from the following.
Assertion : Cell is the basic unit of life.
Reason : Robert Hooke discovered the cell.

A
Both A and R are true, and R is the correct explanation of A.

B
Both A and R are true, but R is not the correct explanation of A.

C
A is true but R is false.

D
A is false but R is true.

Solution

Cell is the basic unit of life according to cell theory. Cell was discovered by Robert Hooke. for the first time.
Question 4
1 / -0

Directions : In the following question, the Assertions (A) and Reason (R) have been put forward. Read both the statements and choose the correct option from the following.
Assertion : Schleiden and Schwann were the first to observe the cells to put cell theory .
Reason : Anton Von Leeuwenhoek saw and described a living single cell

A
A. Both A and R are true, and R is the correct explanation of A.

B
B. Both A and R are true, but R is not the correct explanation of A.

C
C. A is true but R is false.

D
D. A is false but R is true.

Solution

This was Anton von Leeuwenhoek not Schleiden and Schwann, who was the first to give the idea of cell theory. Anton Von Leeuwenhoek first saw single cell bacteria and protozoa.
Question 5
1 / -0

Directions : In the following question, the Assertions (A) and Reason (R) have been put forward. Read both the statements and choose the correct option from the following.
Assertion : Chloroplasts and mitochondria are
treated as self-autonomous organelles.
Reason : In bacteria, small circular DNA molecules are present in cytoplasm.

A
A. Both A and R are true, and R is the correct explanation of A.

B
B. Both A and R are true, but R is not the correct explanation of A.

C
C. A is true but R is false.

D
D. A is false but R is true.

Solution

Chloroplasts and mitochondria are treated as self-autonomous organelles because of the presence of this DNA molecule.
In bacteria, additional to the genomic DNA, small circular DNA molecules are present in cytoplasm. These small molecules are called plasmids.
Question 6
1 / -0

Directions : In the following question, the Assertions (A) and Reason (R) have been put forward. Read both the statements and choose the correct option from the following.
Assertion : All cells are autonomous.
Reason : Each and every cell converts non-living materials into components of living matter.

A
A. Both A and R are true, and R is the correct explanation of A.

B
B. Both A and R are true, but R is not the correct explanation of A.

C
C. A is true but R is false.

D
D. A is false but R is true.

Solution

All cells are autonomous totipotent because each and every cell converts non-living materials into components of living matter.

Directions : In the following question, the Assertions (A) and Reason (R) have been put forward. Read both the statements and choose the correct option from the following.
Assertion : Elaioplast is a kind of leucoplast.
Reason : It is involved in storage of oils and fats.

A
A. Both A and R are true, and R is the correct explanation of A.

B
B. Both A and R are true, but R is not the correct explanation of A.

C

D
D. A is false but R is true.

Solution

Elaioplast is a kind of leucoplast, which are involved in storage of oils and fats.
Question 8
1 / -0

Directions : In the following question, the Assertions (A) and Reason (R) have been put forward. Read both the statements and choose the correct option from the following.
Assertion : Chloroplasts are found in all the eukaryotic cells.
Reason : They perform the function of photosynthesis as they trap energy.

A
A. Both A and R are true, and R is the correct explanation of A.

B
B. Both A and R are true, but R is not the correct explanation of A.

C
C. A is true but R is false.

D
D. A is false but R is true.

Solution

Chloroplast is found in all green cells which perform the function of photosynthesis. It traps energy.
Question 9
1 / -0

Directions : In the following question, the Assertions (A) and Reason (R) have been put forward. Read both the statements and choose the correct option from the following.
Assertion : RER is lined with 80S ribosomes and is rough in appearance.
Reason : It is the site of lipid and steroid synthesis.

A
A. Both A and R are true, and R is the correct explanation of A.

B
B. Both A and R are true, but R is not the correct explanation of A.

C
C. A is true but R is false.

D
D. A is false but R is true.

Solution

RER is lined with 80S ribosomes and is rough in appearance, hence, named as rough endoplasmic reticulum. It is the site of protein synthesis and not of lipid synthesis.
Question 10
1 / -0

Directions : In the following question, the Assertions (A) and Reason (R) have been put forward. Read both the statements and choose the correct option from the following.
Assertion : Smaller cells metabolically more active than larger cells.
Reason : Metabolically active cells are usually larger due to lower nucleo-cytoplasmic ratio.

A
A. Both A and R are true, and R is the correct explanation of A.

B
B. Both A and R are true, but R is not the correct explanation of A.

C
C. A is true but R is false.

D
D. A is false but R is true.

Solution

Metabolically active cells are usually smaller due to higher nucleocytoplasmic ratio. The former will allow the nucleus to have better of metabolic activities while the latter will allow quicker exchange of materials between the cells.
