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

Cell theory was proposed by a German botanist, Matthias Schleiden and English zoologist, Theodor Schwann in the year 1839. Cell theory was considered as the most acceptable theory which, elucidated the functioning of a cell. 

The cell theory includes the following points -

(1) All living things are made up of cells.
(2) The cell is the smallest living thing that can perform all the functions of life.

Assertion & Reason Test: Cell: The Unit of Life - Question 5
Save

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:
Mitochondria and chloroplast are semiautonomous organelles.
Reason:
They are formed by division of preexisting organelles as well as contain DNA but lack protein-synthesizing machinery.
 

Detailed Solution: Question 5

Mitochondria are cell organelles found in large numbers in cells.
They contain their own DNA that can replicate independently and can also produce its own ribosomes and have the ability for protein synthesis. These characteristics make the mitochondria semi-autonomous and not completely autonomous as the structure and the functioning of mitochondria are controlled by the nucleus of the cell and are dependent on the availability of materials from the cytoplasm. Similarly, like mitochondria, chloroplasts also contain their own DNA and reproduce independently, but these depend on the nuclear genome for the majority of the protein and enzyme requirements. They are inherited by the daughter cells during the cell division. Mitochondria are known as the powerhouse of the cell because it helps in the synthesis of ATP molecules. Chloroplasts are present only in animal cells and in algae. It has a green-coloured pigment called chlorophyll that helps in the process of photosynthesis.
Therefore, the correct answer is option D.

Assertion & Reason Test: Cell: The Unit of Life - Question 6
Save

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.

Detailed Solution: Question 6

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

Assertion & Reason Test: Cell: The Unit of Life - Question 7

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.

Detailed Solution: Question 7

Elaioplast is a kind of leucoplast, which are involved in storage of oils and fats.

Assertion & Reason Test: Cell: The Unit of Life - Question 8

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.

Detailed Solution: Question 8

Chloroplast is found in all green cells which perform the function of photosynthesis. It traps energy.

Assertion & Reason Test: Cell: The Unit of Life - Question 9
Save

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.

Detailed Solution: Question 9

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.

Assertion & Reason Test: Cell: The Unit of Life - Question 10
Save

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.

Detailed Solution: Question 10

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.
