The process by which a modified stem or root of a parent plant grows offspring that remain attached is called

vegetative reproduction.
vegetative reproduction.

binary fission.
binary fission.

tuber reproduction.
tuber reproduction.

fragmentation

fragmentation

The correct answer is vegetative reproduction.

The correct term for the process by which a modified stem or root of a parent plant grows offspring that remain attached is "vegetative reproduction."

To arrive at this answer, you can break down the options provided and analyze the definitions of each term:

1. Binary fission: This term refers to the asexual reproduction in which a single parent organism divides into two equal parts, each of which then grows into an individual organism. It is mostly seen in single-celled organisms like bacteria.

2. Tuber reproduction: Tubers are enlarged, underground plant structures that store nutrients. While tubers like potatoes can be used for vegetative reproduction, the term itself does not encompass the process described in the question.

3. Fragmentation: Fragmentation is a process in which a parent organism breaks into pieces, and each piece grows into a new individual. It is commonly observed in plants like ferns and some types of algae.

4. Vegetative reproduction: This process involves the growth of offspring from stems, roots, or leaves of a parent plant without the involvement of seeds. Clonal plants, such as strawberries and spider plants, reproduce through vegetative reproduction.

Considering the explanations provided, the correct term for the described process is "vegetative reproduction."
