Organelle Function(s)
Nucleus Contains genetic material (DNA), controls cell activities.
Mitochondria Generates ATP through cellular respiration (energy production).
Chloroplasts Site of photosynthesis, where plants produce sugars using light energy.
Endoplasmic Reticulum (ER) Rough ER: Synthesizes and processes proteins. Smooth ER: Lipid synthesis and detoxification.
Golgi Apparatus Modifies, sorts, and packages proteins and lipids for transport.
Lysosomes Contains enzymes for intracellular digestion and waste removal.
Peroxisomes Breaks down fatty acids and detoxifies harmful substances.
Ribosomes Protein synthesis by reading mRNA and assembling amino acids.
Vacuoles Store water, ions, nutrients, and waste products in plant cells.
Cilia and Flagella Hair-like structures for cell movement or moving substances along the cell surface.
Centrioles Organize microtubules during cell division.
Cell Membrane Controls the movement of substances in and out of the cell.
Cell Wall (in plants) Provides structural support and protection for plant cells.
