STUDY
PLAY
Golgi apparatus
Stack of membranes in the cell that modifies, sorts, and packages proteins from the endoplasmic reticulum
cilium
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
chloroplast
responsible for converting sunlight into chemical energy
plasma cell membrane
thin, flexible barrier around a cell; regulates what enters and leaves the cell
lysosome
contains digestive enzymes; breaks down lipids, carbs and proteins and worn out organelles
cytoskeleton
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
centriole
one of two tiny structures located in the cytoplasm near the nuclear envelope; helps in mitosis
nucleus
controls most cell processes and contains hereditary information (DNA)
vacuole
cell organelle that stores materials such as water, salts, proteins, and carbohydrates
mitochondria
the powerhouse of the cell, responsible for the production of ATP (energy)
ribosome
produces proteins by following coded instructions from the nucleus
nucleolus
small, dense region within most nuclei in which the assembly of proteins begins
pseudopod
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
cytoplasm
Jello-like material inside every cell that supports the organelles & accounts for approximately 50% of a cells volume
chromatin
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
Flagellum
Whip like structure on the outside of some animal cells that aids in movement
vesicle
storage and delivery structure that is often found by the golgi complex
