Answer: Reticulate (net-like).
- A Parallel venation as seen in monocots
- B Reticulate (net-like)
- C Circular venation around the leaf margin
- D No veins at all, just diffuse vascular tissue
Correct answer: B. Reticulate (net-like)
Explanation: Dicots have reticulate (net-like) venation where veins form a network. Monocots have parallel venation where veins run parallel from base to tip.
Plants evolved from water-dependent algae through increasingly land-adapted groups, gaining vascular tissue (Pteridophyta), then seeds (Gymnosperms), and finally fruit-enclosed seeds (Angiosperms) - each step reducing dependence on water for reproduction.
Concept context
Classification of plants from algae to angiosperms. Understanding plant diversity is essential for NEET.
