Eukaryotic cell evolved from prokaryotic organisms by a process of intracellular symbosis
- an outermost boundary that comes into direct contact with environment - usually composed of polysaccharides - Appears as a network of fibers, a slime layer or capsule
|Nucleus (CONTROL CENTER)||
compact sphere that is prominent organelle of eukaryotic cells
is the site for ribosomal RNA synthesis and a collection area for ribosomal subunits
|Endoplasmic Reticulum (ER)||
microscopic series of tunnels used in transport synthesis and storage.
originates from the outer membrane of the nuclear envelope and extends in a continuous network through the cytoplasm
function in synthesis, storage and transport, but mainly of non-protein molecules such as lipids
|Golgi apparatus (golgi complex)||
site in the cell in which proteins are collected and packaged for transport to their final destinations.
type of vesicle from the golgi. Involved in intracellular digestion of food particles and in protection again invading microorganisms
- contain enzymes to digest food - secrete to digest outside the cell - enlargement and repair of cell wall
membrane bound sacs containing fluids or solids particles to be digested
Energy generator of the cell
