Step-by-step solution for: Animal Cell Label Organelles — Printable Worksheet
The image provided is a detailed diagram of an animal cell. The task appears to be identifying and labeling the various organelles and structures within the cell. Below, I will identify each labeled part (A through Q) and explain its function.
---
1. A - Rough Endoplasmic Reticulum (RER):
- Function: Involved in protein synthesis and transport. It has ribosomes attached to its surface, which are responsible for producing proteins.
2. B - Smooth Endoplasmic Reticulum (SER):
- Function: Produces lipids and steroids, detoxifies harmful substances, and stores calcium ions.
3. C - Golgi Apparatus (Golgi Body):
- Function: Modifies, sorts, packages, and distributes proteins and lipids produced by the endoplasmic reticulum.
4. D - Lysosome:
- Function: Contains digestive enzymes that break down waste materials and cellular debris. They also play a role in apoptosis (cell death).
5. E - Peroxisome:
- Function: Breaks down fatty acids and other substances, and neutralizes toxins like hydrogen peroxide.
6. F - Mitochondrion:
- Function: The powerhouse of the cell; it generates energy in the form of ATP through cellular respiration.
7. G - Nucleus:
- Function: Contains the cell's genetic material (DNA) and controls cellular activities such as growth, metabolism, and reproduction.
8. H - Nuclear Envelope:
- Function: A double membrane surrounding the nucleus, with nuclear pores allowing the passage of molecules between the nucleus and cytoplasm.
9. I - Nuclear Pore:
- Function: Allows the exchange of materials (e.g., RNA and proteins) between the nucleus and the cytoplasm.
10. J - Ribosome:
- Function: Sites of protein synthesis. Some are free in the cytoplasm, while others are attached to the rough endoplasmic reticulum.
11. K - Cytoskeleton:
- Function: Provides structural support, maintains cell shape, and aids in intracellular transport and movement.
12. L - Vesicle:
- Function: Small, membrane-bound sacs that transport materials within the cell or to the outside of the cell.
13. M - Centriole:
- Function: Involved in organizing microtubules during cell division (mitosis). Found in pairs near the nucleus.
14. N - Plasma Membrane (Cell Membrane):
- Function: Regulates the movement of substances in and out of the cell, providing a boundary between the cell's interior and the external environment.
15. O - Cilia:
- Function: Hair-like structures on the cell surface that aid in movement (e.g., sweeping mucus in the respiratory tract).
16. P - Flagellum:
- Function: Long, whip-like structure used for locomotion (e.g., sperm cells use flagella to move).
17. Q - Vacuole:
- Function: Stores water, nutrients, and waste products. In animal cells, vacuoles are generally smaller compared to plant cells.
18. R - Cytoplasm:
- Function: Gel-like substance inside the cell where most cellular activities occur. It contains organelles and supports their functions.

Each organelle plays a critical role in maintaining the cell's functionality. For example:
- The nucleus acts as the control center, storing genetic information.
- The endoplasmic reticulum (both rough and smooth) is involved in protein and lipid production.
- The mitochondria generate energy through ATP production.
- The Golgi apparatus modifies and packages proteins for secretion or internal use.
Understanding these structures helps in comprehending how cells perform their essential functions.
