Mark the correct statement

Options

A. the body of sponges consists of epithelial tissue only
B. all the four types of tissues are seen in the body of the sponges
C. only epithelial and connective tissues are present
D. structually organised tissues are absent in the body of sponges

Answer

To solve the question "Mark the correct statement," we will evaluate the given statements about sponges and determine which one is correct.

### Step-by-Step Solution:

1. **Identify the Statements**: The question requires us to analyze the statements provided about sponges, which belong to the phylum Porifera.

2. **Evaluate the First Statement**:
- The first statement claims, "The body of sponges consists of epithelial tissue only."
- This statement is **incorrect** because sponges do not have a true tissue organization. They have a cellular level of organization, meaning they do not have organized tissues like epithelial, connective, muscular, or nervous tissues.

3. **Evaluate the Second Statement**:
- The second statement states, "All the four types of tissues are seen in the body of sponges."
- This statement is also **incorrect**. As mentioned earlier, sponges do not exhibit organized tissues. They are made up of different cell types but lack the true tissue organization found in higher animals.

4. **Evaluate the Third Statement**:
- The third statement is not provided in the transcript, but we can assume it would also be incorrect based on the context.

5. **Evaluate the Fourth Statement**:
- The fourth statement likely asserts that "Structurally organized tissues are absent in the body of sponges."
- This statement is **correct**. Sponges have a simple body structure that lacks organized tissues, which is a defining characteristic of the phylum Porifera.

6. **Conclusion**: Based on the evaluation of the statements, the correct answer is the fourth statement, which accurately describes the body structure of sponges.

### Final Answer:
The correct statement is: "Structurally organized tissues are absent in the body of sponges."
