Cytoplasm of ovum does not contain:

Options

A. Ribosomes
B. Mitochondria
C. Golgi bodies
D. Centrosomes

Answer

To answer the question "Cytoplasm of ovum does not contain:", we will analyze the components typically found in the cytoplasm of an ovum and identify which one is absent.

### Step-by-Step Solution:

1. **Understanding the Ovum Structure**: The ovum, or egg cell, is a large cell that contains cytoplasm rich in nutrients and organelles necessary for the early stages of development after fertilization.

2. **Components of the Cytoplasm**:
- **Ribosomes**: These are present in the cytoplasm of the ovum and are essential for protein synthesis.
- **Mitochondria**: These organelles are also found in the ovum and are responsible for producing energy (ATP) required for cellular processes.
- **Golgi Bodies**: The Golgi apparatus is involved in modifying, sorting, and packaging proteins for secretion or use within the cell, and it is present in the ovum's cytoplasm.
- **Centrosomes**: These structures are typically involved in cell division and organizing microtubules. However, they are not found in the cytoplasm of the ovum.

3. **Conclusion**: Since ribosomes, mitochondria, and Golgi bodies are present in the cytoplasm of the ovum, but centrosomes are not, we conclude that the cytoplasm of the ovum does not contain centrosomes.

### Final Answer:
The cytoplasm of the ovum does not contain **centrosomes**.
