Question

which type of asexual reproduction does a gardener cause when they cut a stem from a plant and pot it to grow a new plant?

spores

fragmentation

apomixis

binary fission

Explanation:

1. Spores: These are specialized reproductive units produced by fungi, mosses, ferns, used for asexual/sexual reproduction, not stem cuttings.
2. Fragmentation: This is a form of asexual reproduction where an organism is split into fragments, and each fragment grows into a fully mature, independent individual. A gardener cutting a plant stem and regrowing it fits this definition.
3. Apomixis: This is asexual reproduction via seeds, without fertilization, no physical fragmentation involved.
4. Binary fission: This is prokaryotic cell division for single-celled organisms like bacteria, not applicable to plants.

Answer:

B. fragmentation
