Answer: Floridean starch.
- A Floridean starch
- B Laminarin starch
- C Simple glycogen
- D Stored inulin
Correct answer: A. Floridean starch
Explanation: Red algae store carbohydrate as floridean starch, a polymer similar to glycogen and amylopectin.
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.
