Here is the correct labeling for the animal cell diagram, with explanations for each organelle:
---
Top Left (from top to bottom):
1.
Cell membrane
→ The outer boundary of the cell that controls what enters and exits.
2.
Ribosomes
→ Small dots (often seen on rough ER or floating freely) — they synthesize proteins.
3.
Nucleus
→ Large central organelle that contains DNA and controls cell activities.
4.
Vacuole
→ Large, fluid-filled sac; in animal cells, usually smaller than in plant cells — stores nutrients and waste.
5.
Centrioles
→ Paired cylindrical structures near the nucleus; involved in cell division (spindle formation).
6.
Mitochondrion
→ Bean-shaped organelles with inner folds (cristae); produce energy (ATP) via cellular respiration.
7.
Lysosome
→ Small, round vesicles containing digestive enzymes; break down waste materials and cellular debris.
---
Top Right (from top to bottom):
8.
Nucleolus
→ Dark spot inside the nucleus; site of ribosome assembly.
9.
Rough ER (Endoplasmic Reticulum)
→ Network of membranes studded with ribosomes; synthesizes and modifies proteins.
10.
Smooth ER
→ Membrane network without ribosomes; synthesizes lipids and detoxifies chemicals.
11.
Golgi Body (Golgi Apparatus)
→ Stacked, flattened sacs; modifies, sorts, and packages proteins for secretion or delivery.
12.
Cytoplasm
→ Gel-like substance filling the cell; surrounds organelles and is where many metabolic reactions occur.

📌 *Note: In this diagram, the arrows point from left to right, top to bottom. The labels are assigned based on standard biological knowledge and visual identification of organelles.*
