TERM 1
Membranous Organelles
DEFINITION 1 `Mitochondria, Nucleus, Endoplasmic Reticulum (ER), Golgi Apparatus, Lysosome, Peroxisome TERM 2
Nonmembranous Organelles
DEFINITION 2 Cytoskeleton, Microvilli, Centrosome and Centrioles, Cilia, Ribosomes. TERM 3
What are the two types of cells in the body?
DEFINITION 3 Sex cells = sperm and oocytesSomatic cells = all the other cells within the human body. TERM 4
extracellular fluid
DEFINITION 4 the watery medium that the cell floats around in. TERM 5
The Plasmalemma (Cell Membrane)
DEFINITION 5 the outer boundary of the cell General Functions include: physical isolation, regulation of exchange with the environment, sensitivity, cell-to-cell communication.
TERM 6
Plasmalemma phospholipid bilayer
DEFINITION 6 heads are at the surface and the tails are in inside heads = polar, tails = non polar the polarity of the bilayer makes it effective in keeping dissolved ions and water-soluble compounds out. there are 2 types of proteins that allow compounds = ions in.
- peripheal proteins 2. integral proteins TERM 7
Peripheral and Integral Proteins
DEFINITION 7 Peripheral proteins are attached to either the inner or outer membrane surface Integral proteins are embedded in the bilayer integral proteins form channels throughout cell to transport nutrients and communicate between interior and exterior. some of the channels are gated channels = selectively permeable.
