Answer: Female sex organ that contains the egg cell; found in bryophytes, pteridophytes, and some gymnosperms.
- A Generates haploid spores released for dispersal by wind or water currents overall in most cases
- B Female sex organ that contains the egg cell; found in bryophytes, pteridophytes, and some gymnosperms
- C Produces and releases pollen grains containing the male gametophyte structure under typical conditions
- D A modified photosynthetic leaf structure specialized for vegetative reproduction methods according to standard textbooks
Correct answer: B. Female sex organ that contains the egg cell; found in bryophytes, pteridophytes, and some gymnosperms
Explanation: Archegonium is the flask-shaped female sex organ in bryophytes, pteridophytes, and gymnosperms (not in angiosperms). It contains a single egg cell. Fertilization occurs inside the archegonium.
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.
