Cell organelles concerned with the formation of cell plate are
I. Golgi complex
II. Lysosomes
III. Ribosomes
IV. Mitochondria

Options

A. I and II are correct
B. I and III are correct
C. III and IV correct
D. I only

Answer

To determine which cell organelles are involved in the formation of the cell plate, we need to analyze each of the given options:

1. **Golgi Complex**:
- The Golgi complex, also known as the Golgi apparatus, plays a crucial role in the formation of the cell plate during cell division in plants. It is responsible for synthesizing and packaging the materials needed for the formation of the cell plate. Thus, this option is correct.

2. **Lysosomes**:
- Lysosomes are often referred to as "suicidal bags" because they contain digestive enzymes that break down waste materials and cellular debris. They do not play a role in the formation of the cell plate. Therefore, this option is incorrect.

3. **Ribosomes**:
- Ribosomes are the cellular structures responsible for protein synthesis. They do not have any direct involvement in the formation of the cell plate. Thus, this option is also incorrect.

4. **Mitochondria**:
- Mitochondria are known as the powerhouses of the cell because they are involved in cellular respiration and energy production. They do not contribute to the formation of the cell plate. Therefore, this option is incorrect as well.

Based on the analysis:
- The only organelle that is concerned with the formation of the cell plate is the **Golgi complex**.

**Final Answer**: The cell organelle concerned with the formation of the cell plate is **I. Golgi complex**.
