Answer: Requiring two compatible mating types (+/-) from different individuals for sexual reproduction.
- A Possessing two structurally distinct hyphal types within a single mycelium
- B Requiring two compatible mating types (+/-) from different individuals for sexual reproduction
- C Alternating between sexual spore formation and asexual conidial budding within one cycle
- D Growing simultaneously across two physically separate nutrient substrates
Correct answer: B. Requiring two compatible mating types (+/-) from different individuals for sexual reproduction
Explanation: Heterothallic fungi require two compatible mating types (+ and -) from different individuals for sexual reproduction. Homothallic fungi can self-fertilize. Understanding this is important for fungal genetics and breeding programs.
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.
