Illustration of a plant cell with labeled organelles.

- The cell is a plant cell because it has a cell wall, chloroplasts, and a large central vacuole.
- The large blue structure is the central vacuole, which stores water and maintains turgor pressure.
- The green oval structures are chloroplasts, responsible for photosynthesis.
- The red oval structures with internal folds are mitochondria, which produce energy (ATP) through cellular respiration.
- The yellow structure with a nucleolus is the nucleus, which contains DNA and controls cell activities.
- The purple folded structure is the endoplasmic reticulum (ER), involved in protein and lipid synthesis.
- The blue stacked discs are the Golgi apparatus, which modifies, sorts, and packages proteins.
- The small purple dots are ribosomes, where protein synthesis occurs.
- The orange border is the cell wall, providing structural support and protection.
- The green outer layer is the plasma membrane, regulating what enters and exits the cell.
