Golgi apparatus

Stack of membranes in the cell that modifies, sorts, and packages proteins from the endoplasmic reticulum


short hairlike projection similar to a flagellum; produces movement in many cells

endoplasmic reticulum

internal membrane system in cells in which lipid components of the cell membrane are assembled and some proteins are modified


responsible for converting sunlight into chemical energy

plasma cell membrane

thin, flexible barrier around a cell; regulates what enters and leaves the cell


contains digestive enzymes; breaks down lipids, carbs and proteins and worn out organelles


network of protein filaments within some cells that helps the cell maintain its shape and is involved in many forms of cell movement; includes microtubules and filaments


one of two tiny structures located in the cytoplasm near the nuclear envelope; helps in mitosis


controls most cell processes and contains hereditary information (DNA)


cell organelle that stores materials such as water, salts, proteins, and carbohydrates


the powerhouse of the cell, responsible for the production of ATP (energy)


produces proteins by following coded instructions from the nucleus


small, dense region within most nuclei in which the assembly of proteins begins


temporary projection of cytoplasm, or a "false foot", used by some protists for feeding or movement

cell wall

some cells, ex plants, have this extra barrier around them, offering support & protection


Jello-like material inside every cell that supports the organelles & accounts for approximately 50% of a cells volume


A disorganized form of DNA bound to protein; it condenses into chromosomes when a cell divides

nuclear envelope

the layer that surrounds and protects the nucleus

nuclear pore

the holes in the nuclear envelope that enables selective permeability into/out of the nucleus


Whip like structure on the outside of some animal cells that aids in movement


storage and delivery structure that is often found by the golgi complex
