List the steps of the cell cycle.
|
Interphase
Prophase Metaphase Anaphase Telophase |
|
|
Describe interphase.
|
longest, cell processes carried out, chromosomes duplicate, grows and develops
|
|
|
Describe prophase.
|
first and longest part of mitosis
chromatin coil up into chromosomes |
|
|
describe metaphase
|
chromosomes line up at equator
|
|
|
describe anaphase
|
chromatid pairs pull apart
|
|
|
describe telophase
|
final phase
chromosomes unwind to chromatin nucleus re-appear |
|
|
What is telophase called in animal cells? plant?
|
animal=cleavage furrow
plant=cell plates |
|
|
What is cytokinesis and in which phase does it occur?
|
Telophase, when cytoplasm splits.
|
|
|
what happens when cell divide out of control?
|
cancer
|
|
|
What is diffusion?
|
molecules move from high concentration to low concentration
|
|
|
what is osmosis?
|
diffusion of water molecules
|
|
|
what is facilitated diffusion?
|
"diffusion w/ help"
membranes are example b/c of carrier proteins which carry molecules across the membrane |
|
|
what is active transport?
|
material goes from low to high concentration
ENERGY REQUIRED |
|
|
3 factors affecting diffusion?
|
-concentration: more concentrated molecules faster it diffuses
-temperature: warmer temp. quicker diffusion -pressure: more pressure, quicker diffusion |
|
|
hypotonic solution has water going?
|
into cell
|
|
|
hypertonic solution has water going?
|
out of the cell
|
|
|
isotonic solution has water going?
|
equally in and out [basically none moves]
|
|
|
what is endocytosis?
|
cell engulfs substance

|
|
two types of endocytosis are?
|
Phagocytosis
Pinocytosis |
|
|
what is phagocytosis?
|
solid materials absorb
|
|
|
what is pinocytosis?
|
liquid absorbed
|
|
|
what is exocytosis?
|
cell expels material
|
|
|
name 6 differences between plant and animal cells.
|
-plant has cell wall
-plant has chloroplast -plant has 1 vacuole -plants are bigger -plants are more square -plants have cell plates |
|
|
what is the smooth er job?
