Zoospores are

Options

A. motile , asexual spores found in fungi and algae
B. motile , sexual spores found in fungi and algae
C. non - motile , asexual spores found in fungi and algae
D. non - motile , sexual spores found in fungi and algae

Answer

**Step-by-Step Solution:**

1. **Definition of Zoospores**: Zoospores are small, motile spores that are capable of swimming. They are primarily found in certain groups of organisms, including fungi and algae.

2. **Characteristics of Zoospores**:
- They are known as "swimmers" due to their ability to move through aquatic environments.
- Their small size and motility allow them to reach the female gametes, which are typically non-motile.

3. **Reproductive Role**:
- In the context of reproduction, zoospores function as male gametes in some organisms, particularly in the plant kingdom (specifically angiosperms).
- In fungi and algae, zoospores are typically asexual spores, meaning they are produced without the fusion of gametes.

4. **Ploidy Level**:
- In fungi and algae, zoospores are produced in a diploid condition (2n), which means they contain two sets of chromosomes.
- In contrast, in angiosperms, they are haploid (n), which means they have one set of chromosomes.

5. **Correct Option Identification**:
- The question asks for the correct characterization of zoospores.
- The correct option is that they are "motile, asexual spores in fungi and algae."
- Other options that describe them as sexual or non-motile are incorrect.

**Final Answer**: Zoospores are motile, asexual spores found in fungi and algae.
