The image provided is a diagram of a human cell, and the task is to label the various parts of the cell using the terms from the "Word Bank" on the left. Below is the solution with explanations for each labeled part:
---
1. Cell coat
- Located at the outermost layer of the cell.
- This is the extracellular matrix or glycocalyx, which is not typically shown in basic diagrams but is present outside the plasma membrane.
2. Centriole
- Found near the nucleus, often depicted as small cylindrical structures.
- Involved in cell division (mitosis).
3. Chromatin
- Found within the nucleus.
- The material that makes up chromosomes when the cell is not dividing.
4. Cytoplasm
- The gel-like substance inside the cell membrane but outside the nucleus.
- Contains organelles and other cellular components.
5. Free ribosome
- Small, granular structures scattered throughout the cytoplasm.
- Involved in protein synthesis.
6. Golgi body (Golgi apparatus)
- A stack of flattened sacs near the nucleus.
- Modifies, sorts, and packages proteins and lipids for secretion or use within the cell.
7. Lysosome
- Small, round vesicles containing digestive enzymes.
- Break down waste materials and cellular debris.
8. Mitochondrion
- Bean-shaped structures with an inner and outer membrane.
- The powerhouse of the cell, where cellular respiration occurs to produce energy (ATP).
9. Nuclear envelope
- The double-layered membrane surrounding the nucleus.
- Regulates the movement of substances in and out of the nucleus.
10. Nuclear pore
- Small openings in the nuclear envelope.
- Allow the passage of molecules between the nucleus and cytoplasm.
11. Nucleolus
- A dense region within the nucleus.
- Site of ribosome production.
12. Nucleus
- The large, central structure surrounded by the nuclear envelope.
- Contains the cell's genetic material (DNA).
13. Plasma membrane
- The outer boundary of the cell.
- Regulates what enters and exits the cell.
14. Ribosome
- Small, granular structures attached to the endoplasmic reticulum or free in the cytoplasm.
- Sites of protein synthesis.
15. Rough endoplasmic reticulum (RER)
- Network of membranous tubules with ribosomes attached to their surface.
- Involved in protein synthesis and transport.
16. Smooth endoplasmic reticulum (SER)
- Network of membranous tubules without ribosomes.
- Involved in lipid synthesis, detoxification, and calcium storage.

- Cell coat: Although not explicitly visible in this diagram, it refers to the extracellular matrix or glycocalyx, which is a layer of carbohydrates and proteins outside the plasma membrane.
- Centriole: These are involved in organizing microtubules during cell division.
- Chromatin: This is the uncondensed form of DNA in the nucleus, which condenses into chromosomes during cell division.
- Cytoplasm: This is the fluid medium where most cellular activities occur.
- Free ribosome: These are ribosomes that float freely in the cytoplasm and synthesize proteins that remain in the cytoplasm.
- Golgi body: This modifies and packages proteins and lipids for secretion or use within the cell.
- Lysosome: These contain digestive enzymes and break down waste materials and cellular debris.
- Mitochondrion: These are the sites of cellular respiration, producing ATP, the energy currency of the cell.
- Nuclear envelope: This is the double membrane that surrounds the nucleus and regulates the movement of substances in and out.
- Nuclear pore: These are openings in the nuclear envelope that allow the passage of molecules like RNA and proteins.
- Nucleolus: This is the site of ribosome production within the nucleus.
- Nucleus: This is the control center of the cell, containing the genetic material (DNA).
- Plasma membrane: This is the boundary of the cell, regulating what enters and exits.
- Ribosome: These are the sites of protein synthesis, either free in the cytoplasm or attached to the endoplasmic reticulum.
- Rough endoplasmic reticulum (RER): This has ribosomes attached and is involved in protein synthesis and transport.
- Smooth endoplasmic reticulum (SER): This lacks ribosomes and is involved in lipid synthesis, detoxification, and calcium storage.

Each part of the cell should be labeled according to the corresponding term from the Word Bank. The labels are explained above, and the final diagram should have all parts correctly identified.
