![**Cell Structure and Function**
The provided image is a detailed diagram of an animal cell, labeled with various organelles. Below is a description of each labeled part to help students understand the structure and function of the cell.
1. **Smooth Endoplasmic Reticulum (Smooth ER):**
- An organelle responsible for lipid synthesis and detoxification of drugs and poisons.
2. **Microvilli:**
- Small, finger-like projections from the cell surface that increase surface area for absorption.
3. **Golgi Apparatus:**
- A series of stacked membranes that modify, sort, and package proteins and lipids for storage or transport out of the cell.
4. **Rough Endoplasmic Reticulum (Rough ER):**
- Studded with ribosomes, it is involved in protein synthesis and production.
5. **Mitochondrion:**
- The powerhouse of the cell, involved in energy production through cellular respiration.
6. **Centrosome:**
- A structure involved in organizing microtubules and regulating the cell division cycle.
7. **Ribosomes:**
- Small structures either floating freely in the cytoplasm or attached to the Rough ER, they are the site of protein synthesis.
8. **Peroxisome:**
- Organelles containing enzymes to break down fatty acids and detoxify harmful substances.
9. **Nucleus:**
- The control center of the cell, containing genetic material (DNA) and responsible for regulating all cell activities.
10. **Cytoskeleton:**
- A network of fibers (microtubules, actin filaments, and intermediate filaments) that maintain the cell’s shape, secure organelles in specific positions, and allow the cell to move.
11. **Lysosome:**
- Small organelles filled with enzymes that digest cellular waste and pathogens.
12. **Endoplasmic Reticulum (ER):**
- A network of membranes involved in protein and lipid synthesis. There are two types: Rough ER (with ribosomes) and Smooth ER (without ribosomes).
