An advantage of asexual reproduction in plants is

1. A. reproduction without another parent
2. C. Can help a species better adapt to environmental changes
3. B. Addition energy needs to complete a life cycle
4. C. haploid gameotype
5. C. fruit

The correct answer is option 2: C. Can help a species better adapt to environmental changes.

Now, let me explain how to arrive at this answer.

To determine the advantages of asexual reproduction in plants, let's consider the options one by one:

1. A. Reproduction without another parent: This statement is true for asexual reproduction in plants. However, it does not specifically highlight any advantage.

2. C. Can help a species better adapt to environmental changes: This statement represents a potential advantage of asexual reproduction. By reproducing asexually, plants can replicate themselves without the need for a mate. This allows for rapid, efficient reproduction, which can be advantageous in changing environments, as it enables the species to quickly spread and colonize new areas.

3. B. Addition energy needs to complete a life cycle: This statement does not directly relate to the advantages of asexual reproduction in plants. It may represent a general factor in the life cycle of any organism, but it does not specifically highlight an advantage of asexual reproduction.

4. C. Haploid gametophyte: This statement describes a specific stage in the life cycle of plants. While the haploid gametophyte is an important component of plant reproduction, it does not directly address the advantages of asexual reproduction.

5. C. Fruit: This statement also does not directly pertain to the advantages of asexual reproduction. Fruit is associated with the dispersal of seeds, which is relevant to sexual reproduction in plants.

Considering the explanations above, option 2: C. Can help a species better adapt to environmental changes, is the correct answer as it specifically highlights an advantage of asexual reproduction in plants.
