This zoomed-in image clearly shows an oval-shaped organelle with internal folds, which are called cristae. This is a mitochondrion. The line pointing to this structure is indicating the mitochondrion.
Based on my analysis of the image, I can now label all the parts of the animal cell:
- The large, central organelle is the
nucleus.
- Inside the nucleus, the smaller, dense structure is the
nucleolus.
- The double membrane surrounding the nucleus is the
nuclear envelope.
- The outer boundary of the entire cell is the
cell membrane.
- The jelly-like substance filling the cell is the
cytoplasm.
- The oval-shaped organelles with internal folds are
mitochondria.
- The small, dot-like structures scattered throughout the cytoplasm are
ribosomes.
- The series of flattened, stacked sacs is the
Golgi apparatus.
- The network of membranes surrounding the nucleus is the
endoplasmic reticulum.
- The small, circular sacs are
lysosomes.
Therefore, the correct labels for the animal cell are:
- Nucleus
- Nucleolus
- Nuclear envelope
- Cell membrane
- Cytoplasm
- Mitochondria
- Ribosomes
- Golgi apparatus
- Endoplasmic reticulum
- Lysosomes
