Difficulty: Easy
Correct Answer: (iii), (i), (iv), (ii)
Explanation:
Introduction / Context:
“Logical sequence of words” items check whether you can order real-world concepts into a natural progression. For plant reproduction, we should respect the well-known biological cycle from initial propagule to vegetative growth, flowering, and fruiting. Each step must follow causally from the previous one.
Given Data / Assumptions:
Concept / Approach:
The standard angiosperm sequence is Seed → (germination) → Seedling/Plant → Flower → Fruit (with new seeds). A correct answer must reflect this causality. Putting fruit before flower, or plant after fruit, breaks biology.
Step-by-Step Solution:
Start with (iii) Seed → germinates into (i) Plant.The plant reaches reproductive maturity and produces (iv) Flower.Post-pollination and fertilization, the flower develops into (ii) Fruit.
Verification / Alternative check:
Cross-check against any proposed order: fruit cannot precede flowering; a plant cannot follow the fruit stage it produced.
Why Other Options Are Wrong:
Common Pitfalls:
Final Answer:
(iii), (i), (iv), (ii).
