Cell Parts
Cell Membrane
• Selectively permeable = allows certain
substances in/out of cell
Nucleus
•
•
•
•
“Brain” of cell
Control center
Stores DNA
Synthesizes RNA
and ribosomes
Cytoplasm (Cytosol)
• Gelatin-like fluid inside cell
Mitochondria
• “Powerhouse of the cell”
• Where energy is made if the form of ATP
Ribosome
• Synthesis of proteins
• “Protein factories”
Endoplasmic Reticulum (ER)
• Rough ER = prepares proteins for export out of
cell
– Ribosomes are covered with ribosomes
• Smooth ER = makes steroids, regulates
calcium, and breaks down toxins
Golgi Apparatus
• Processes, packages, and secretes substances
produced by the cell
Lysosomes
• Digests molecules, old organelles, and foreign
substances
Cell Wall
• Plant Cells and Protists Only!
• Supports and protects the cell
Vacuole
• Plant cells and Protists Only!
• Stores water and waste products
Chloroplast
• Plant Cells and Protists Only!
• Green Pigment (chlorophyll)
• Photosynthesis
Animal Cell
Plant Cell
