A student made the following significant observation for the given cell sample . Cell has large quantities of rough endoplasmic reticulum and many Golgi bodies. Which type of cell can it be ?

Options

A. Guard Cell
B. Bacterium
C. Lymphocyte
D. Mesophyll

Answer

To determine the type of cell based on the observations of large quantities of rough endoplasmic reticulum (RER) and many Golgi bodies, we can follow these steps:

### Step 1: Analyze the Observations
The observations indicate that the cell has a large amount of rough endoplasmic reticulum and numerous Golgi bodies. The rough endoplasmic reticulum is primarily involved in the synthesis of proteins, especially those that are secreted or incorporated into membranes.

**Hint:** Consider the functions of rough endoplasmic reticulum and Golgi bodies in relation to the cell's role.

### Step 2: Identify the Function of the Cell
Cells that have a high amount of rough endoplasmic reticulum and Golgi bodies are typically involved in the production and processing of proteins. This is characteristic of cells that secrete proteins, such as antibodies.

**Hint:** Think about which cells are known for producing and secreting large amounts of proteins.

### Step 3: Consider the Types of Cells
Among the options provided:
- **Lymphocytes** are a type of white blood cell (WBC) that play a crucial role in the immune response and produce antibodies, which are proteins.
- **Gut cells** are specialized plant cells involved in gas exchange and do not have a high amount of RER.
- **Bacteria** lack membrane-bound organelles, including RER and Golgi bodies.
- **Mesophyll cells** are plant cells involved in photosynthesis and do not primarily focus on protein synthesis.

**Hint:** Recall which type of cell is known for its role in the immune system and protein synthesis.

### Step 4: Conclude the Type of Cell
Given the observations of large quantities of rough endoplasmic reticulum and many Golgi bodies, the cell in question is most likely a **lymphocyte**. Lymphocytes have a significant amount of RER and Golgi bodies to support their function in producing antibodies.

**Hint:** Remember that lymphocytes are part of the immune system and are essential for producing proteins like antibodies.

### Final Answer
The type of cell observed is a **lymphocyte**.
