CELL FUNCTIONS NOTE SHEET
1) Nucleus-Structure that contains DNA and directs the cell
2) Nuclear Envelope-serves as the physical barrier, separating the contents of the
nucleus (DNA in particular) from the cytosol (cytoplasm).
3) Chromatin-string like formations that are found in the nucleus and that condense to
form chromosomes
4) Chromosomes-organized structure of DNA and protein found in cells.
5) Nucleolus-Structure that manufactures ribosomes
6) Ribosomes-small structure that synthesizes proteins
7) Cytoplasm-Jelly-like substance within the plasma membrane
8) Endoplasmic Reticulum-passage ways where chemicals are made
9) Smooth ER/Rough Er-The rough ER has Ribosomes on it
10) Golgi Body-Stack of membranes that package chemicals
11) Vacuoles-used for storage
12) Lysosomes-sac filled with digestive chemicals
13) Mitochondria-Structures that converts nutrients into energy
(Power House of the cell)
14) Plastids- Plastids are the site of manufacture and storage of important chemical
compounds used by the cell. Plastids often contain pigments used in photosynthesis
FOUND IN PLANTS
15) Chloroplasts-contains chlorophyll. Found ONLY in PLANT CELLS
16) Cilia –small hair like structures that are used for movement
17) Flagella-Long tail like structure that is used for movement
18) Centrioles-structure that organizes motion of chromosomes during cell
division.
19) Cytoskeleton-is a cellular "scaffolding" or "skeleton" contained within a cell's
cytoplasm and is made out of protein
