cell membrane
the semi-permeable phospholipid bilayer that covers eukaryotic cells
nucleus
the largest organelle and the cells manager, also contain the DNA in the cell
nuclear membrane
covers the nucleus
chromatin
the material inside of the nucleus
nucleolus
inside of the nucleus and is responsible for ribosome production
cytoplasm
the fluid medium with in the inner boundary of the cell membrane in which the organelles float
Endoplasmic Reticulum
or the ER is a folded membrane around the nucleus that is rough and has ribosomes that produce proteins or is smooth and processes lipids
ribosomes
small spheres made inside the nucleolus that produce proteins
golgi body
an organelle that packages and secretes proteins from one area of the cell to another or from one cell to another
vesticle
small protein bearing sacs formed from sections of the golgi body
mitochondria
the powerhouse of the cell where glucose is broken down for cellular respiration
chloroplast
responsible for the production of chemical energy through photosynthesis (only found in plant cells)
lysosome
breaks down disfunctioning parts of the cell so they can be used for other things
peroxisome
recycles hydrogen peroxide into H20 and oxygen
microfilaments
part of the cytoskeleton that aids in cell shape, structure and movement
microtubules
part of the cytoskeleton that aids in cell shape, structure and movement as well as a tube to send things through
centrioles
aid in animal cell division (only found in animal cells)
vacuole
temporary cell storage organelles for food, wastes or H20
cell wall
a semi rigid, porous structure composed of a cellulose network that surrounds the cell and provides structure
