PARASAGITTAL PLANE
7
Serves as the interface between the interior of the cell and the extracellular fluid that bathes all cells
Plasma Membrane

Regulates the exchange of vital substance between the content of the cells and its external environment
CELL MEMBRANE
9
It serves as gate way and barrier for cell. Are amphilic with hydrocarbon tail of the molecule
PHOSPHOLIPIDS
10
Role of proteins in cell is for transport of molecules/ions into or out of cells
MEMBRANE PROTEIN
11
Breaks up Van der Woals interaction and close packing of phospholipid tails. This disruption makes the membrane more fluid.

15
a network of flattened, interweaving tubules which are formed by membrane within the cell
ENDOPLASMIC RETICULUM
16
This are long chains of amino acids
POLYPEPTIDES
17
Synthesizing proteins. It is large assemblies of RNA and dozens of different proteins synthesized in nuclear eukaryotoes.
RIBOSOMES
18
It consist of layers of sacs. It acts in the modification of lipids and proteins. It serves to store and package materials for exportation from the cell.
GOLGI COMPLEX

This type of cytoskeleton filaments are describe as straight hollow cylinder. Which highly participate in a wide variety of cell activities especially in motion
MICROTUBULES
31
__________ it is the process of forming (generally) identical daughter cells by replecsting and dividing original chromosomes, in effect making cellular xerox. Deals with the segregation of chromosomes and organelles into daughter cells
MITOSIS
