Answer
Correct Answer: c, a, d, b, e
Explanation
Introduction / Context:This sequence problem uses common plant organs and asks for a logical development chain. While actual growth can be concurrent, a clean educational order highlights foundational to reproductive components.
Given Data / Assumptions:
- Parts: Root, Stem, Leaves, Flower, Fruit.
- Goal: A meaningful learning order from support/uptake to reproduction and yield.
Concept / Approach:Roots establish anchorage and absorption first, stems provide support and transport, leaves enable photosynthesis (powering growth), flowers are reproductive structures, and fruit is the post-fertilization product.
Step-by-Step Solution:1) Root (c) → earliest essential organ for water/mineral uptake.2) Stem (a) → supports and conducts.3) Leaves (d) → photosynthetic surfaces for energy.4) Flower (b) → reproduction.5) Fruit (e) → result of fertilization.
Verification / Alternative check:School-level botany diagrams follow the same conceptual order when teaching structure and function.
Why Other Options Are Wrong:
- c, a, e, b, d: Puts fruit before leaves; unrealistic.
- e, b, a, d, c: Starts with fruit; reversed logic.
- d, c, a, e, b: Begins with leaves, ignoring foundational roots.
- c, d, a, b, e: Swaps stem and leaves; typical pedagogy introduces stem before leaves.
Common Pitfalls:Thinking that leaves must appear before stems; structurally, stems are the framework for leaves.
Final Answer:c, a, d, b, e
