Working on animal cells. Have to label what make up an animal cell in order 1-8 of the following; nucleus, cell membrane, vacuole, cytoplasm, mitochondria, goligi body, endoplasmic reticulum, ribosome??? Not sure where to start

To label the components of an animal cell in order, you can follow these steps:
1. Nucleus: The nucleus is often considered the control center of the cell. It contains the genetic material and coordinates the cell's activities. It's usually located in the center of the cell.
2. Cell membrane: The cell membrane acts as a protective barrier and controls the movement of substances in and out of the cell. It encloses the entire cell and separates the internal environment from the external environment.
3. Cytoplasm: The cytoplasm is a gel-like substance that fills the cell. It contains various organelles and is involved in many cellular processes.
4. Mitochondria: Mitochondria are responsible for producing energy in the form of ATP. They are often referred to as the "powerhouses" of the cell. Look for small, bean-shaped structures with a folded inner membrane.
5. Golgi body (Golgi apparatus): The Golgi body is involved in processing and packaging proteins and lipids for transport within or outside the cell. It looks like a stack of flattened, membranous sacs.
6. Endoplasmic reticulum (ER): The endoplasmic reticulum is a network of membranes connected to the nucleus. It plays a role in protein synthesis and lipid metabolism. The rough ER has ribosomes attached, which gives it a bumpy appearance.
7. Vacuole: Vacuoles are membrane-bound sacs that serve various functions such as storing water, nutrients, and waste products. In animal cells, vacuoles are generally smaller and more scattered compared to plant cells.
8. Ribosome: Ribosomes are involved in protein synthesis. They can be found either floating freely in the cytoplasm or attached to the rough ER. They appear as small dots or granules.
Start by identifying the nucleus (typically larger and centrally located), then locate the cell membrane. From there, you can observe the cytoplasm and search for specific organelles like mitochondria, the Golgi body, endoplasmic reticulum, vacuole (if visible), and ribosomes. Remember, the exact appearance and arrangement of organelles may vary, but these general characteristics will help you label them accurately.
