Step-by-step solution for: Label the Parts of the Plant and Animal Cell
The image provided is a labeled diagram of an animal cell. Below, I will explain the function and identification of each labeled part of the cell:
1. 1 - Mitochondrion
- Function: The powerhouse of the cell. It produces energy in the form of ATP (adenosine triphosphate) through cellular respiration.
2. 2 - Ribosome
- Function: Small structures where proteins are synthesized. They can be found either free in the cytoplasm or attached to the endoplasmic reticulum.
3. 3 - Nucleolus
- Function: A dense region within the nucleus where ribosomal RNA (rRNA) is synthesized and ribosomal subunits are assembled.
4. 4 - Nuclear Envelope
- Function: A double membrane that surrounds the nucleus, separating it from the cytoplasm. It has nuclear pores for the passage of molecules.
5. 5 - Chromatin
- Function: The material inside the nucleus consisting of DNA and associated proteins. It condenses into chromosomes during cell division.
6. 6 - Nuclear Pore
- Function: Openings in the nuclear envelope that allow the transport of molecules (e.g., RNA and proteins) between the nucleus and the cytoplasm.
7. 7 - Nucleus
- Function: The control center of the cell. It contains the genetic material (DNA) and controls cellular activities.
8. 8 - Cilia
- Function: Hair-like structures on the cell surface that aid in movement (e.g., moving substances along the cell surface).
9. 9 - Rough Endoplasmic Reticulum (RER)
- Function: Membrane-bound network involved in protein synthesis and modification. It has ribosomes attached to its outer surface.
10. 10 - Smooth Endoplasmic Reticulum (SER)
- Function: Membrane-bound network involved in lipid synthesis, detoxification, and calcium storage. It lacks ribosomes.
11. 11 - Golgi Apparatus
- Function: Modifies, sorts, packages, and distributes proteins and lipids produced by the cell. It is often referred to as the "post office" of the cell.
12. 12 - Lysosome
- Function: Contains digestive enzymes that break down waste materials and cellular debris. It acts as the cell's recycling center.
13. 13 - Centriole
- Function: Involved in organizing the microtubules of the mitotic spindle during cell division. Found in pairs near the nucleus.
14. 14 - Plasma Membrane (Cell Membrane)
- Function: The boundary of the cell that regulates the movement of substances in and out of the cell.

The diagram illustrates the structure of an animal cell, with each labeled component representing a specific organelle or structure. Understanding the functions of these components is crucial for comprehending how cells perform their various tasks. Here’s a summary of the key points:
- Energy Production: Mitochondria (1) generate ATP, which powers cellular activities.
- Protein Synthesis: Ribosomes (2) produce proteins, while the rough ER (9) modifies them.
- Genetic Control: The nucleus (7) houses the DNA and controls gene expression.
- Transport and Packaging: The Golgi apparatus (11) modifies and packages proteins for secretion or intracellular transport.
- Digestion: Lysosomes (12) break down waste materials and cellular debris.
Each organelle plays a vital role in maintaining the cell's functionality and survival.
The diagram represents an animal cell, with each labeled part corresponding to a specific organelle or structure. The functions of these parts have been explained above.
