State whether the following statements are true or false.
Motile reproductive bodies are completely absent in Rhodophyta.
A. True
B. False

Answer

To determine whether the statement "Motile reproductive bodies are completely absent in Rhodophyta" is true or false, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Rhodophyta**:
- Rhodophyta, commonly known as red algae, is a diverse group of marine organisms.

2. **Identify Reproductive Structures**:
- In Rhodophyta, the reproductive structures include the egg, which is referred to as the Carpogonium.

3. **Examine Male Gametes**:
- The male gametes in Rhodophyta are called spermatia.

4. **Assess Motility of Spermatia**:
- It is important to note that spermatia are non-motile. This means they do not have the ability to move on their own.

5. **Conclude on Motile Reproductive Bodies**:
- Since Rhodophyta only has non-motile reproductive bodies (spermatia) and no motile reproductive bodies, the statement that "Motile reproductive bodies are completely absent in Rhodophyta" is indeed true.

6. **Select the Correct Option**:
- Therefore, the correct answer is A. True.

### Final Answer:
A. True
