Answer: Micro- and megasporophylls.
- A Coloured petals and sepals
- B Open flowers and fruits
- C Micro- and megasporophylls
- D Root rhizoids and thalli
Correct answer: C. Micro- and megasporophylls
Explanation: Gymnosperm cones carry microsporophylls (bearing pollen sacs) and megasporophylls (bearing ovules).
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.
