Cell Parts and Their Jobs
What are Cells? Basic units of all living things Building blocks of life Needed for growing, repairing/replacing damaged cells
Cell Membrane Location: Surrounds all cells Function: Gives the cell shape Controls what moves into and out of cell
Cytoplasm Location: Throughout the cell Function: Clear, jellylike material Provides cushion for all organelles
Nucleus Location: Near center of cell Function: Controls cell’s activities Contains genetic information in the form of chromosomes/DNA
Nuclear Membrane/Envelope Location: Surrounds the nucleus Function: Protects nucleus from the rest of the cell Openings (pores) allow materials to move into and out of nucleus
Nucleolus Location: Inside the nucleus Function: Makes ribosomes
Chromatin Location: Inside the nucleus Function: Threadlike structures that determine what traits a living thing will have “genetic blueprints” for cell operations
Chromosomes Location: Inside the nucleus Function: Pairs of DNA Contain instructions for cell activities
DNA : Deoxyribonucleic Acid Location: Inside the nucleus Function: Creates genes: determine traits of organisms Contains information for making proteins
Endoplasmic Reticulum (ER) Location: Cytoplasm Function: Network of tubes in the cell Transports materials from nucleus to cytoplasm- throughout cell Smooth ER-no ribosomes Rough ER-has ribosomes
Ribosomes Location: Cytoplasm or on the Rough ER Function: make proteins
Golgi Bodies Location: Cytoplasm Function: Curved sacs that package/store proteins
Mitochondria Location: Cytoplasm Function: “Powerhouses” of the cell Sausage shaped Breaks down nutrients to produces energy “Powerhouses” of the cell
Vacuole Location: Cytoplasm Function: Larger in plant cells Stores food, water, and wastes Larger in plant cells Helps support the plant
Lysosomes Location: Cytoplasm Function: Mainly found in Animal Cells Digests proteins, food, water, and worn out cell parts Mainly found in Animal Cells
Cell Wall Location: surrounds plant cells Outside cell membrane Rigid, non-living Function: Protect and support cell
Chloroplasts Location: Cytoplasm Contain green pigment chlorophyll Function: Change light energy to sugar [glucose] during Photosynthesis
Plastid Location: Cytoplasm Function: Contains pigments to give plants color
