17

Cytoplasm

18

Rough endoplasmic reticulum (RER)

19

Ribosome

20

Golgi complex/apparatus

Cytoskeleton

Network of three different types of protein filaments; plays important role in maintaining cell shape and structure, promoting cellular movement, and aiding cell division

Mitochondria

Creates ATP

Endoplasmic reticulum

Smooth and rough network of folded membranes

Rough endoplasmic reticulum (RER)

studded with numerous ribosomes which are sites of protein synthesis

Smooth endoplasmic reticulum (SER)

synthesizes phospholipids and steroid hormones (no attached ribosomes, so looks smooth)

Flagella

locomotion/movement of the cell itself

Cytoplasm

Region of the cell between the plasm membrane and the nucleus; cell’s internal environment

Golgi apparatus/complex

flattened membranous sacs for creating and exporting vesicles; Organizes, modifies, packages, sorts, and tags proteins from the ER

Cilia

hairlike structures that move substances along the outside of the cell

Cytosol

Fluid portion of the cytoplasm

Lysosome

Contains digestive enzymes

Ribosome

Protein production/synthesis

Nucleus

control center of the cell

Plasma/cell membrane

acts as gatekeeper allowing only specific substances in or out (phospholipid bilayer)

Isolates the cell’s internal environment (cytoplasm) from the external environment by being selective

Regulates exchange of what can enter and exit the cell

Communicates with other cells

Centrioles

Plays a critical role in cell division (responsible for forming the mitotic spindle when cell division occurs)

Organelles

specialized structures inside the cell

Chromatin

thread-like matter composed of DNA

Nucleoli/nucleous

one or more in cell; where ribosomes are produced

Nuclear membrane (envelope)

double layer that contains pores

Microvilli

small folds that increase surface area if the cell; in small intestine
