Task: Label the parts of an animal cell and match them with their functions.

#### Image Description:
The image shows a detailed diagram of an animal cell with numbered labels. The task is to identify each part of the cell based on its function and match it with the corresponding label in the diagram.

#### Functions Provided:
1. Facilitates ribosome biogenesis.
2. Contains the majority of the cell's DNA.
3. The site of protein synthesis in the cell.
4. It organizes intracellular substances.
5. Involves in production, folding, quality control, and dispatch of some proteins.
6. Packages and secretes proteins.
7. Helps cells maintain shape and internal organization.
8. Synthesizes lipids, plasma membranes, and steroids.
9. Helps turn energy from the food we eat into energy.
10. Handles and gets rid of waste products.
11. Involved in signal transduction between the cell membrane and the nucleus and organelles.
12. Rids cells of waste products and scavenges metabolic building blocks.
13. Organizes microtubules that serve as the cell's skeletal system.

Solution:

#### Matching the Functions with Cell Parts:
1. Facilitates ribosome biogenesis.
- Nucleolus (Label: 1)
The nucleolus is responsible for producing ribosomes, which are essential for protein synthesis.

2. Contains the majority of the cell's DNA.
- Nucleus (Label: 2)
The nucleus is the control center of the cell and houses most of the cell's genetic material (DNA).

3. The site of protein synthesis in the cell.
- Ribosomes (Label: 10)
Ribosomes are where mRNA is translated into proteins.

4. It organizes intracellular substances.
- Cytoplasm (Label: 8)
The cytoplasm is the gel-like substance inside the cell that contains all the organelles and helps organize cellular components.

5. Involves in production, folding, quality control, and dispatch of some proteins.
- Endoplasmic Reticulum (ER) (Label: 5)
The ER, especially the rough ER, is involved in protein synthesis, folding, and transport.

6. Packages and secretes proteins.
- Golgi Apparatus (Label: 6)
The Golgi apparatus modifies, sorts, packages, and transports proteins and lipids for secretion or use within the cell.

7. Helps cells maintain shape and internal organization.
- Cytoskeleton (Label: 7)
The cytoskeleton provides structural support and maintains the cell's shape.

8. Synthesizes lipids, plasma membranes, and steroids.
- Smooth Endoplasmic Reticulum (SER) (Label: 9)
The smooth ER is involved in lipid synthesis, detoxification, and steroid production.

9. Helps turn energy from the food we eat into energy.
- Mitochondria (Label: 4)
Mitochondria are the powerhouses of the cell, where cellular respiration occurs to produce ATP (energy).

10. Handles and gets rid of waste products.
- Lysosomes (Label: 12)
Lysosomes contain digestive enzymes that break down waste materials and cellular debris.

11. Involved in signal transduction between the cell membrane and the nucleus and organelles.
- Endoplasmic Reticulum (ER) (Label: 5)
The ER, along with other organelles, plays a role in signal transduction pathways.

12. Rids cells of waste products and scavenges metabolic building blocks.
- Lysosomes (Label: 12)
Lysosomes degrade waste materials and recycle cellular components.

13. Organizes microtubules that serve as the cell's skeletal system.
- Centrosome (Label: 13)
The centrosome organizes the microtubules of the cytoskeleton and is involved in cell division.
