The image provided is a diagram of an animal cell, and the task is to label the various parts of the cell. Below is the solution with explanations for each labeled part:
Labeled Parts of the Animal Cell:
1.
Nucleus (1)
- The nucleus is the control center of the cell. It contains the cell's DNA, which carries genetic information.
2.
Nuclear Membrane (2)
- Also known as the nuclear envelope, it is a double membrane that surrounds the nucleus and regulates the movement of substances in and out of the nucleus.
3.
Nucleolus (3)
- A dense region within the nucleus where ribosomal RNA (rRNA) is synthesized and ribosomes are assembled.
4.
Endoplasmic Reticulum (ER) (4)
- A network of membranous tubules and sacs involved in protein and lipid synthesis. There are two types:
-
Rough ER: Covered with ribosomes, involved in protein synthesis.
-
Smooth ER: Lacks ribosomes, involved in lipid synthesis and detoxification.
5.
Golgi Apparatus (5)
- A stack of flattened sacs that modifies, sorts, and packages proteins and lipids for transport to their final destinations within or outside the cell.
6.
Mitochondrion (6)
- The powerhouse of the cell, responsible for producing energy in the form of ATP through cellular respiration.
7.
Ribosome (7)
- Small structures made of RNA and protein where proteins are synthesized. They can be free-floating in the cytoplasm or attached to the rough ER.
8.
Cytoplasm (8)
- The gel-like substance inside the cell membrane where most cellular activities occur. It contains organelles and other cellular components.
9.
Cytoskeleton (9)
- A network of protein fibers (microtubules, microfilaments, and intermediate filaments) that provides structural support, maintains cell shape, and aids in intracellular transport.
10.
Centrioles (10)
- Paired cylindrical structures found near the nucleus, involved in organizing the mitotic spindle during cell division.
11.
Cell Membrane (11)
- The outer boundary of the cell that regulates the movement of substances in and out of the cell and maintains the cell's internal environment.
Final Answer:
1. Nucleus
2. Nuclear Membrane
3. Nucleolus
4. Endoplasmic Reticulum (ER)
5. Golgi Apparatus
6. Mitochondrion
7. Ribosome
8. Cytoplasm
9. Cytoskeleton
10. Centrioles
11. Cell Membrane
Boxed Final Answer:
\[
\boxed{
\begin{array}{ll}
1. & \text{Nucleus} \\
2. & \text{Nuclear Membrane} \\
3. & \text{Nucleolus} \\
4. & \text{Endoplasmic Reticulum (ER)} \\
5. & \text{Golgi Apparatus} \\
6. & \text{Mitochondrion} \\
7. & \text{Ribosome} \\
8. & \text{Cytoplasm} \\
9. & \text{Cytoskeleton} \\
10. & \text{Centrioles} \\
11. & \text{Cell Membrane} \\
\end{array}
}
