Question #2
Consider statements about scientists: 1. Robert Hooke coined the term 'cell'. 2. Antonie van Leeuwenhoek discovered the cell nucleus. 3. Matthias Schleiden proposed that all plants are made of cells. Which are correct?
A. 1 and 2 only
B. 1 and 3 only
C. 2 and 3 only
D. 1, 2 and 3

Correct Answer: Option B


Explanation:
Robert Hooke observed cork tissue in 1665 and coined the term 'cell' to describe the box-like structures. Matthias Schleiden, a botanist, concluded in 1838 that all plants are composed of cells, forming a core tenet of the cell theory. The cell nucleus was discovered by Robert Brown in 1831, not Antonie van Leeuwenhoek, who is famous for discovering living microorganisms. Thus, statements 1 and 3 are correct.

Question #3
Assertion (A): Green plants are called autotrophs.
Reason (R): They can synthesize their own food by photosynthesis.
A. A true, R false.
B. Both A and R are true, and R is the correct explanation.
C. Both A and R are true, but R is not the correct explanation.
D. A false, R true.

Correct Answer: Option B


Explanation:
Autotrophs produce organic compounds from inorganic CO₂ and water using light energy (photosynthesis). This exactly defines green plants. So both are true, and R explains A.
