Difficulty: Easy
Correct Answer: (B), (D), (A), (C)
Explanation:
Introduction / Context:
Sequencing questions based on natural processes reward everyday scientific knowledge. In flowering plants, the usual life-cycle proceeds from a seed that germinates into a seedling; the seedling grows into a mature plant, which then bears flowers and fruit. Recognizing this order allows an unambiguous mapping from biological reality to a list of symbols.
Given Data / Assumptions:
Concept / Approach:
The logic is developmental: a dormant propagule (seed) germinates to an early growth stage (seedling), which matures into the full plant. Only a mature plant produces fruit as a reproductive output. Hence the correct chain is Seed → Seedling → Plant → Fruit.
Step-by-Step Solution:
Start: Seed (B).Next: Seedling (D) by germination.Then: Mature Plant (A) through growth.Finally: Fruit (C) after flowering/reproduction.So the order is (B), (D), (A), (C).
Verification / Alternative check:
Any order placing fruit before plant contradicts reproduction. Any order placing seedling before seed is impossible. The selected sequence uniquely matches the growth pathway.
Why Other Options Are Wrong:
Common Pitfalls:
Interchanging “seedling” and “plant” or overlooking that fruit is an outcome of maturity.
Final Answer:
(B), (D), (A), (C)
