Statement-basedWhich of the following is/are correct?
I. Prokaryotic cells have 70S ribosomes.
II. Prokaryotic cells have mitochondria.
III. Blue-green algae are prokaryotes.

Correct Answer: C [I and III only]

Explanation:

Prokaryotes have no membrane-bound organelles, so II is wrong.

2.  
Data tableRead: Cell X: cellulose wall, plastids, one large vacuole. Cell Y: no wall, centrioles, small vacuoles. Cell Z: wall of chitin, no plastids. Which identification is correct?

Correct Answer: B [X – plant, Y – animal, Z – fungus]

Explanation:

W-V-P → plant; centrioles, no wall → animal; chitin wall without plastids → fungus.

3.  
One cell divides by mitosis; every new cell divides again, for 5 rounds in all. How many cells are formed?

Correct Answer: D [32]

Explanation:

Answer: 32. 2⁵ = 32 (not 2 × 5).

4.  
Match the followingMatch the tissue with its location:
P. Cartilage Q. Adipose tissue R. Cuboidal epithelium S. Ciliated columnar epithelium
1. Kidney tubules 2. Respiratory tract 3. External ear 4. Below the skin

Correct Answer: A [P-3, Q-4, R-1, S-2]

Explanation:

Cartilage – ear; adipose – below skin; cuboidal – kidney tubules; ciliated – respiratory tract.

5.

Reason (R): Mitochondria have their own DNA and ribosomes.

Correct Answer: A [Both A and R are true and R is the correct explanation of A]

Own DNA + ribosomes let them make some of their own proteins – that is why they are semi-autonomous.

6.  
Odd one outOdd one out (living vs dead at maturity):

Correct Answer: C [Companion cells]

Explanation:

Companion cells (phloem) are living; the other three are dead.

7.  
True/False drillhow many are TRUE?
I. Meiosis forms four cells.
II. Mitosis halves the chromosome number.
III. Crossing over takes place during meiosis.
IV. Human gametes carry 23 chromosomes.

Only II is false – mitosis keeps the number.

8.
