Question

3. Assertion (A): Spores are unicellular bodies
Reason (R): The parent body simply breaks up into smaller pieces on
maturation.
a) Both A & R are true and R is the correct explanation of A
b) Both A & R are true but R is not the correct explanation of A
c) A is true but R is false
A is false but R is true​

Answer 1

Answer:

actually the option b is correct one

Answer 2

Both A and R are true but R is not the correct explanation of A. So option B is the right answer.

Assertion: Spores are unicellular bodies.

• Spores are haploid and unicellular organisms. Many unicellular organisms reproduce asexually.

• Spore is a reproductive cell in many plants. These are the agents of asexual reproduction.

• Spores are produced by bacteria, algae, fungi, and plants.

• Spores are produced by meiosis in the sporangium of a diploid sporophyte.

• Under favorable conditions, the spores can develop into a new organism using mitotic division.

• In mitotic division spores generating a multicellular gametophyte, which further develops into gametes.

• Two gametes fuse to create a new sporophyte.

• Spores can produce multicellular organisms in certain favorable conditions.
