DESCRIPTION

Types of Cells Cell membrane- security fence (protects the cell by controlling what enters and exits the cell) Nucleus-control center Ribosomes-make proteins Golgi- post office (packages proteins for storage or secretion) Lysosomes- clean-up crew (eat stuff in the cell that needs disposed of) Mitochondria- power house (makes energy for the cell) Vacuoles- storage Cell Organelles (only in plants) Cell wall- protection and support for the plant cell Chloroplasts- capture energy from the sun and convert it to chemical energy through photosynthesis
