|
Cell Membrane
|
FUNCTION: Control entry and exit of Ions
Selectivly permeable double layer membrane of phospholipids with glycoproteins Protection |
|
Pinocytic Cesicle
|
Piece of membrane that pinches into the cell to ingest materials
|
|
Cytoplasm
|
Between Nuclius and Cell membrane hold organelles
|
|
Endoplasmic Reticulum
|
Protein synthesis and transport
stacs folded membrane that extends from Nuclear envolop/membrane |
|
Ribosomes
|
make protein
made from rRNA and protein |
|
Golgi Body
|
Storage
made up of Protein maturing face is protein products bud off membrane |
|
Lysosome
|
With Digestive enzumes
may rupture as suiced sacs to destroy diseased cell |
|
Mitochondria
"Power House" |
Site of ATP Synthesis
Cristae- fold eith mitochondia |
|
Vacuole
|
Storage
Regulates Pressure in sell Example Aloe |
|
Nucleus
|
Control Center
Houses Chromatin (made up of DNA) |
|
Nucleolus
|
in Nucleus
Special area of chromosomes that make of rRNA |
|
Nuclear membrane
|
double lipid layer with pores to allow (messanger)RNA out of nucleus
|
|
Mictofilaments
|
include actin protein
thin, linear reponsible for contraction |
|
Pseudopodia
|
false foot
movement on Amoeba |
|
Cilia and Flagella
|
extention of cell membrane
movement made of microtubules 9 + 2 arrangement= 9 inside, 2 pair in the middle |
|
Included in Interphase
|
G1 S G2 M
|
|
Interphase
|
Period of no cell division
most mitosis happens her cell carries out routine activites |
|
G1
|
RNA ribosomes, enzymes are made to prpare for DNA synthesis
|
|
S
|
DNA Sythesis/ Duplication
|
|
G2
|
Spindle fiber proteins are made and form band around nucleus
|
|
Mitosis
|
Cell Division
|
|
Prophase
|
Chromatin condenses to Chromosomes
Nuclear membrane dossp;bes Centrids/ centromenes duplicate and migrate to poles |
|
Metaphase
|
Chromosomes align in middle of cell
|
|
Anaphase
|
Centromere splits each goes with its own chromosomes
chromosomes moves to opposite poles spindle fibers shorten |
|
Telophase
|
Chromosomes at opposite poles
Nuclear membrane reforms Spindle Fibers disinigrates Chromosomes become diffused |
|
Cytokinesis
|
division of cytoplasm, cleavage furrow form
|
|
Enzymes
|
special Protein that catalyze nearly all chemicall reactions in cells
|
|
How do Enzymes work
|
speed up chemical reactions y reducing the amount of activation energy needed to break chemical bonds to initiate chemical reaction
|
|
what speeds up Enzymes?
|
high tempuratures, work slower at lower tempuratures
and opperate at neutral pH |
|
Passive Transport

movement of materials without any external source of chemical energy being required
|
|
Brownian Motion
|

caused by kinetic energy by heat |
|
Brownnian mobemtn is the source of what passive transport?
|
diffusion
osmosis facilitated diffusion |
|
diffusion
|
high consentraion to low consentration
Caused by collision beween molecules |
|
Osmosis
|
in waster
molecules move across a semi- permeable or selectively permeable membrane water is more concentrated to low concentration equilibrium |
