What is the function of the nucleoli?
The site where ribosomes are assembled; ribosomes serve as sites for protein synthesis
The cytoplasm is made up of...
What are the three subdivisions of the nucleus?
Nuclear membrane, nucleoli, and Chromatin
-centrioles form spindle
-nuclear membrane disappears
What are the stages of mitosis
Prophase, Metaphase, Anaphase, Telophase
What happens during DNA replication?
-helix uncoils and graduallly seperates into templates
-spindle breaks
-two nuclear membranes and nucleoli appear
What is the plasma membrane made up of?
Lipids, cholesterol, and proteins
What is the function of chromatin?
NOTHING! Until the cell divides, then it makes chromosomes.
-chromosomes travel to center of spindle forming a straight line
-chromosomes move towards poles of cell
The function of the mitochondria is.....
supplying most of the ATP in the cell
DNA replication happens when?
Before mitosis; towards the end of interphase

Smooth --> cholesterol synthesis
Rough --> protein synthesis

"Traffic director" for proteins
Function of Lysosomes
Digesting old or worn-out cells
Three different types of solutions for osmosis

What are the two types of transport?
Passive (doesn't need ATP) and Active (needs ATP)
Two types of passive transport
-Diffusion (simple, facilitated, and osmosis)
The lif cycle of a cell has two parts:
Interphase and Cell Division
Two types of active transport
Solute pumping and bulk transport
Two types of bulk transport
-Endocytosis (in the cell)
-Exocytosis (out of cell)
Substances that need solute pumping
Some sugars, ion and amino acids
