Let's examine each term from List - I and match it with the correct term from List - II.
A) Pyriform-shaped gametes: These are characteristic of the Pheophyceae (IV), commonly known as brown algae. In these algae, the gametes are typically pyriform (pear-shaped) in structure.
B) Auxospores: Auxospores are a type of spore seen in Diatoms (III). Diatoms are a group of algae that produce auxospores when they experience a decrease in cell size after division. These spores help in the regeneration of diatom cells.
C) Carpogonium: Carpogonium is the female reproductive organ found in Rhodophyceae (II), also known as red algae. It is involved in the sexual reproduction process of red algae and produces gametes.
D) Hormogonium: Hormogonia are short, free-living filaments of cells formed in Cyanophyceae (I), commonly referred to as blue-green algae. These filaments can move and are involved in reproduction. Thus, the correct matching is: - A) Pyriform shaped gametes → Pheophyceae (IV) - B) Auxospores → Diatoms (III) - C) Carpogonium → Rhodophyceae (II) - D) Hormogonium → Cyanophyceae (I) Hence, the correct answer is (3) A-IV, B-III, C-II, D-I.
