Question

The table given below shows a list of organisms
and the methods of reproduction. What do W, X, Y and Z represent?

Organism	Method of reproduction
Fern	W
Amoeba	X
Flatworm	Y
Yeast	Z

• A. W-Binary fission, X-Regeneration, Y-Spore formation and Z-Budding
• B. W-Regeneration, X-Binary fission, Y-Budding and Z-Spore formation
• C. W-Budding, X-Spore formation, Y-Binary fission Z-Regeneration
• D. W-Spore formation, X-Binary fission, Y-Regeneration and Z-Budding

Answer 1

The correct option is D W-Spore formation, X-Binary fission, Y-Regeneration and Z-Budding

Fern are Pteridophytes that show alternation of generation. They reproduce by means of spores and gametes formed during the fern life cycle.

Amoeba reproduces by asexual method through binary fission in which the parent cell divides to form two daughter cells.

Flatworm such as Planaria when cut into pieces, each piece regenerates into a complete organism.

Yeast reproduce by budding in which a small outgrowth called bud forms on the parent cell that later on separate to form an independent organism.

Thus the correct answer is option D.
