The image provided is a diagram of an animal cell, and the task is to identify the organelles labeled by numbers. Below is the solution with explanations for each labeled part:

Animal Cell Diagram Labels:
1.
Nucleus
- The nucleus is the control center of the cell. It contains the cell's DNA and is responsible for regulating gene expression and controlling cellular activities.
2.
Nuclear Envelope (Nuclear Membrane)
- This is the double-layered membrane that surrounds the nucleus, separating it from the cytoplasm. It has nuclear pores that allow the passage of molecules like RNA and proteins.
3.
Endoplasmic Reticulum (ER)
- There are two types: rough ER (with ribosomes) and smooth ER (without ribosomes). The rough ER is involved in protein synthesis, while the smooth ER is involved in lipid production and detoxification.
4.
Golgi Apparatus (Golgi Body)
- The Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or delivery to other parts of the cell.
5.
Lysosome
- Lysosomes contain digestive enzymes that break down waste materials and cellular debris. They also play a role in recycling cellular components.
6.
Mitochondrion
- Mitochondria are the powerhouses of the cell. They produce energy in the form of ATP through cellular respiration.
7.
Ribosome
- Ribosomes are small structures where protein synthesis occurs. They can be free-floating in the cytoplasm or attached to the rough ER.
8.
Vacuole
- Vacuoles store substances such as water, nutrients, and waste products. In plant cells, vacuoles are larger, but in animal cells, they are smaller and more numerous.
9.
Cytoplasm
- The cytoplasm is the gel-like substance that fills the cell and surrounds the organelles. It provides a medium for chemical reactions and supports the movement of organelles.
10.
Cell Membrane (Plasma Membrane)
- The cell membrane is a selectively permeable barrier that regulates the movement of substances in and out of the cell. It maintains the cell's internal environment.
