The Parts of a Cell
Organelles
• Little cell structures that have specific functions
• Found in eukaryotes
Cell Membrane
• Cell’s security system
• Surrounds and protects cell
• Controls what enters and exits the cell
Cytoplasm
• Gel-like substance inside the cell
• Where cell processes (chemical reactions) occur
• It is 80% water
Cell Wall
• Tough structure that surrounds and protects plant cells
• Gives cells shape
• Made of cellulose
Nucleus
• Control center of the cell
• Contains directions for the entire cell
• DNA is found here
• Surrounded by a nuclear membrane
Chloroplast
• Green organelle • In plant cells• Photosynthesis• Captures energy from
the sun to make glucose (plant food)
Mitochondria
• Cell’s energy dam
• Stores and releases cell’s energy
• “Powerhouse”
Ribosome
• Protein factories
• Make proteins
• Some float freely in the cytoplasm, others are attached to the E.R.
Endoplasmic Reticulum
• Cell’s railroad track
• Moves materials around in cell
• Smooth - no ribosomes
• Rough – has ribosomes
Golgi Body
• Cell’s post office
• Sorts and packages proteins into vesicles
• Vesicles deliver substances in the cell and also attach to the cell membrane to release materials to the outside
Nucleolus
• Manufactures the proteins that make up the ribosomes
• Found in the nucleus
Lysosome
• Cell’s landfill
• Digests food molecules, cell wastes, and worn out cell parts.
Vacuole
• Temporarily stores food, water, and waste
• Rather large in plant cells
Cytoskeleton
• Framework for the cell
• Helps to maintain shape or change shape of cell

Levels of Organization
Tissue
• A group of cells working together to perform a particular function
Organ
• 2 or more tissues working together to perform a function
