Correct Option
The correct option is (c).
Explanation
The plant body is divided into the root system (underground) and the shoot system (aerial). The stem is the central axis of the shoot system, characterized by the presence of nodes and internodes, and serves as the structural link between the roots and the leaves.
Statement-wise Analysis
- Statement 1 is Incorrect. The primary function of absorbing water and minerals from the soil belongs to the root system, specifically the root hairs. The stem does not absorb water from the soil; rather, it receives water absorbed by the roots.
- Statement 2 is Correct. The stem bears branches, leaves, flowers, and fruits. It arranges leaves to maximize exposure to sunlight for photosynthesis and positions flowers to facilitate pollination.
- Statement 3 is Correct. The stem acts as a pipeline for transport. It conducts water and minerals from the roots to the leaves through the xylem and transports food (photosynthates) from the leaves to other plant parts through the phloem.
Key Takeaway: The fundamental distinction in plant organ function is that roots absorb water and minerals, while the stem conducts these materials and provides structural support for leaves and reproductive organs.
