Answer: Chlorophyceae (green algae).
- A Chlorophyceae (green algae)
- B Phaeophyceae (brown algae)
- C Rhodophyceae (red algae)
- D Cyanophyceae (blue-green)
Correct answer: A. Chlorophyceae (green algae)
Explanation: Chlorophyceae (green algae) have chlorophyll a and b and store food as starch, like land plants.
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.
