Cell Parts

Parts of the cell and functions

TermDefinition
Cell Wall Only located in plant cells. Surrounds cell and gives the cell structure and support.
Cell Membrane Surrounds the cell; acts as a barrier that allows substances to pass in and out of the cell.
Cytoplasm Jelly-like substance outside of the nucleus where all of the organelles are contained.
Flagellum Whip-like tail that helps unicellular organisms move.
Cilia Hair-like projections that help unicellular organisms move (also located in our lungs, esophagus, and nose).
Ribosomes Where protein synthesis takes place; made in the nucleolus.
Oral Groove The cilia sweep food particles into this part of the paramecium before travelling to the gullet.
Lysosomes Small, round vesicles that contain enzymes that digest cell nutrients.
Food Vacuoles Storage pocket for food in paramecium.
Contractile Vacuoles Storage pocket for water in paramecium and Euglena.
Smooth Endoplasmic Reticulum (ER) Transports materials throughout the cell and produces lipids (fats).
Rough Endoplasmic Reticulum (ER) Transports materials throughout the cell and produces proteins; ribosomes attach to it.
Golgi Bodies Sort and package materials such as proteins and carbohydrates into vesicles to be delivered to certain parts of the cell.
Mitochondria Powerhouse of the cell; produce ATP (energy) for the cell to use.
Chloroplast Only found in plant cells; convert light energy of the sun into sugars that can be used by cells.
Vacuoles Vesicles in the cell that store nutrients, waste, or water.
DNA Contains the genetic material and information of the cell.
Nucleolus Where ribosomes are made.
Anal pore Pore through which all waste exits the paramecium
