Which of the following are correctly matched with their mode of reproduction? A: a. Yeast, b. Potato, c. Algae, d. Fungi. B: i. vegetative propagation, ii. spore formation, iii. fragmentation, iv. budding

Yeast reproduces asexually by budding, where a small outgrowth (bud) develops on the parent cell and separates (iv). Potato reproduces by vegetative propagation through its tubers, which have 'eyes' that grow into new plants (i). Algae like Spirogyra reproduce by fragmentation, where the body breaks into pieces that grow into new organisms (iii). Fungi like Rhizopus reproduce by spore formation (ii). Hence the correct matching is a-iv, b-i, c-iii, d-ii.
