Question

• A. gametes
• B. vegetative propagules
• C. spores
• D. none of the above

Answer 1

The correct option is B vegetative propagules

Vegetative propagules are the units of vegetative propagation. Vegetative propagation is a type of asexual reproduction that occurs in plants in which new plant grows from a part of the parent plant or a specialized reproductive structure called vegetative propagule. Vegetative propagules include structures like runner, rhizome, sucker, tuber, offset, bulb, buds, etc. which are capable of giving rise to new offspring.

Gametes are haploid cells which carry half the number of chromosomes. They are also called sex cells. Gametes fuse during fertilisation. Ova is female gamete and sperm is male gamete.

Spores are units of asexual and sexual reproduction which are capable of giving rise to new offspring. Members of the kingdom fungi and simple plants such as algae reproduce through special reproductive structures called spores.
