Mesoglea of ctenophores contain

Options

A. Colloblast
B. Cnidoblast
C. Amoebocytes
D. Germ cells

Answer

To answer the question "Mesoglea of ctenophores contain," we will break down the information step by step.

### Step-by-Step Solution:

1. **Understanding Mesoglea**:
- Mesoglea is a gelatinous substance found in ctenophores (commonly known as comb jellies). It serves as a layer between the outer epidermis and the inner gastrodermis.

2. **Composition of Mesoglea**:
- The mesoglea is primarily composed of a loose layer of jelly-like material. This layer contains various components that contribute to its structure and function.

3. **Key Components**:
- **Muscle Bundles**: Mesoglea contains muscle fibers that help in the movement of ctenophores.
- **Nerve Fibers**: It also includes nerve fibers, which play a crucial role in the nervous system of ctenophores.
- **Elastic Cells**: These cells provide elasticity to the mesoglea.
- **Amoebocytes**: These are specialized cells that perform functions such as phagocytosis, helping in the immune response and nutrient absorption.

4. **Evaluating Options**:
- The question may provide multiple-choice answers. Based on our understanding:
- Coloblasts: These are specialized cells for capturing prey, not found in mesoglea.
- Nidoblasts: These are related to the formation of stinging cells in cnidarians, not present in ctenophores.
- Amoebocytes: These are indeed present in the mesoglea and are involved in various functions including phagocytosis.
- Germ Cells: These are involved in reproduction and are not a component of mesoglea.

5. **Conclusion**:
- Based on the analysis, the correct answer is that the mesoglea of ctenophores contains **Amoebocytes**, along with muscle bundles and nerve fibers.

### Final Answer:
The mesoglea of ctenophores contains **Amoebocytes**.
