Difficulty: Easy
Correct Answer: c, a, d, b, e
Explanation:
Introduction / Context:The question checks biological sequencing: structural organs that appear early (for support and nutrition) precede reproductive organs and products.
Given Data / Assumptions:
Concept / Approach:Use functional dependency: vegetative structures (root, stem, leaves) must exist before reproductive stages (flower, fruit).
Step-by-Step Solution:1) Root (c) establishes absorption/anchorage.2) Stem (a) provides support/transport pathways.3) Leaves (d) generate food via photosynthesis.4) Flower (b) forms for reproduction.5) Fruit (e) forms post-fertilization.
Verification / Alternative check:Fruits cannot exist without prior flowering; flowers are energy-intensive and typically follow leaf development.
Why Other Options Are Wrong:Any order that puts fruit before flower or leaves after fruit contradicts plant biology.
Common Pitfalls:Assuming leaves can come after flowers; while there are exceptions in nature, the educationally standard order is vegetative first, reproductive later.
Final Answer:c, a, d, b, e
