"Palade particles "refer to

Options

A. Micro bodies
B. Plastids
C. Ribosomes
D. Lysosomes

Answer

**Step-by-Step Solution:**

1. **Understanding the Term "Palade Particles":**
- The term "Palade particles" is associated with a specific type of cellular structure that was first described by a scientist named George Palade.

2. **Identifying the Options:**
- The options given are Microbodies, Plastids, Ribosomes, and Lysosomes. We need to determine which of these is referred to as "Palade particles."

3. **Analyzing Each Option:**
- **Microbodies:** These are small membrane-bound vesicles containing various enzymes, found in both plant and animal cells. However, they are not referred to as Palade particles.
- **Plastids:** These organelles are primarily found in plant cells and are involved in photosynthesis and storage. They are not referred to as Palade particles.
- **Ribosomes:** These are granular structures that are involved in protein synthesis. They were first observed by George Palade in 1953, which is why they are known as Palade particles.
- **Lysosomes:** These contain hydrolytic enzymes and are involved in the breakdown of waste materials. They are not referred to as Palade particles.

4. **Conclusion:**
- Based on the analysis, the correct answer is **Ribosomes**, as they are the structures referred to as Palade particles.

**Final Answer:**
Palade particles refer to **Ribosomes**.
