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).

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
