-Prokaryotes include the kingdoms of Monera (simple
bacteria). Simply stated, prokaryotes are molecules
surrounded by a membrane and cell wall. Prokaryotic cells
lack characteristic eukaryotic subcellular membrane
enclosed "organelles", but may contain membrane systems
inside a cell wall.
-Prokaryotic cells may have photosynthetic pigments, such
as is found in cyanobacteria ("blue bacteria"). Some
prokaryotic cells have external whip-like flagella for
locomotion or hair like pili for adhesion.
Basic structure The basic eukaryotic cell contains the
1. plasma membrane
2. glycocalyx (components external to the plasma membrane)
3. cytoplasm (semifluid)
4. cytoskeleton - microfilaments and microtubules that suspend
organelles, give shape, and allow motion
5. presence of characteristic membrane enclosed subcellular
Organelles (Parts of the Cell)
1. Cell Membrane
Allows certain materials to move into and out
of the cell. “GATEKEEPER”
Directs all cell Activities
“The Control Center”
Releases energy stored in food.
“Power Plant of the Cell”
Rough endoplasmic reticulum (RER)
Moves materials around the cell.
Smooth endoplasmic reticulum (SER)
Synthesis and metabolism of lipids.
