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 Organelle Cell Tissue Organ Organ System Organism

Tissue A group of cells working together to perform a particular function

Organ 2 or more tissues working together to perform a function
