Arrange the basic parts of a flowering plant from the part that anchors in soil upward to reproductive structure: (a) Leaf (b) Stem (c) Root (d) Flower Choose the correct logical sequence (root → stem → leaf → flower).
-
Ad c a b
-
Ba b c d
-
Cc b a d
-
Db a d c
-
ENone of these
Answer
Correct Answer: c b a d
Explanation
Introduction / Context:Plant morphology questions often require ordering structural parts by function or position. Roots anchor and absorb water/minerals; the stem supports and transports; leaves photosynthesize; flowers are reproductive structures.
Given Data / Assumptions:
- Root is the subterranean anchoring organ.
- Stem connects root to aerial parts, conducting water and food.
- Leaf is attached to stem for photosynthesis.
- Flower is the reproductive part borne on stem/branches.
Concept / Approach:Order by physiological path: resource uptake → transport/support → synthesis → reproduction.
Step-by-Step Solution:Start: c) Root.Then: b) Stem.Then: a) Leaf.Finally: d) Flower.Hence: c, b, a, d.
Verification / Alternative check:Each part’s function depends on the previous (e.g., flower requires resources delivered via stem).
Why Other Options Are Wrong:Any order putting flower or leaf before root/stem breaks functional dependency.
Common Pitfalls:Arranging by size rather than function/position.
Final Answer:c, b, a, d
