Cell Organelles

Cytoplasm Location Description Function Plant and Animal Cells Jelly-like substance that fills the area between the nucleus and cell membrane. Function Where cellular activities occur. Gives cell support and shape.

Cell Membrane Location Description Function Plant and Animal Gate keeper Phospholipid Bilayer Function Allows substances in and out of the cell

Cytoskeleton Location Description Function Animal cell Long thin tubes of protein Function Provide support and strength Helps to maintain shape.

Rough Endoplasmic Reticulum (ER) Location Plant and Animal Cells Description System of membranes found in the cell’s cytoplasm Contains ribosomes Function Production, processing, and transport of proteins

Smooth Endoplasmic Reticulum (ER) Location Plant and Animal Cells Description System of membranes found in the cell’s cytoplasm Function Production of lipids

Ribosome Location Description Function Plant and Animal Cells Cell organelle composed of RNA and protein (little balls) Attached to membranes or free in cytoplasm Function Site of protein synthesis

Golgi Apparatus Location Plant and Animal Cells Description Flattened, slightly curved sacs, (like the ER) Function Collects, modifies, and packages proteins

Vesicle Location Description Function Plant and animal cells Forms at the top layer of the Golgi apparatus Function Store and transport within the cell

Lysosome Location Description Function Plant and Animal Cells Small spherical organelles Function Contains digestive enzymes Breaks down worn out organelles, debris, and particles in the cell

Mitochondria Location Description Function Plant and Animal Cells Surrounded by two membranes Looks like a kidney bean Highly folded inner membrane Function “Powerhouse” Site of cellular respiration which produces ATP

Centriole Location Description Function Plant and Animal Cells Found in the nucleus Function Organize cytoskeleton Used in cell division

Nucleus Location Description Function Plant and Animal Cells Membrane bound organelle Contains DNA Function Control center Contains the DNA

Nucleolus Location Description Function Plant and Animal Cells Found inside nucleus Function Produces ribosomes

Chromosomes Location Description Function Plant and Animal Cells Structure in the nucleus made of DNA and protein Function Contains genetic info

Nuclear Envelope (Membrane) Location Plant and Animal Cell Description Surrounds the nucleus Lipid bilayer enclosing the nucleus Function Allows only certain things to pass in or out of the nucleus through nuclear pores

Flagella Location Description Function Animal cells Whip-like structure Function Movement

Cilia Location Description Function Animal cells (occasionally plant) Hair-like structure Function Movement

Cell Wall Location Description Function Plant A rigid structure that surrounds the cell membrane Function Provides structure, support and protection.

Chloroplasts Location Description Function Plant cells 2 membranes surround it Has its own DNA Function Supply energy Uses light energy to make carbohydrates from CO2 and water

Vacuole Location Description Function Plant cells Membrane bound sac Stores water and may contain substances like ions, nutrients, and wastes
