Mr. Pettra Anatomy Final Ch 3

Front 1

What are the three main parts of a cell?

Back 1

plasma membrane
cytoplasm
nucleus

Front 2

what does the plasma membrane do

Back 2

regulates the flow of material into and out of a cell

Front 3

cytoplasm

Back 3

consists of all the cellular contents between the plasma membrane and nucleus

Front 4

cytosol

Back 4

fluid portion of cytoplasm

Front 5

organelles

Back 5

each has a characterisitc structure and specifid functions

Front 6

chemical composition of the plasma membrane

Back 6

consists mostly of phospholipids
virtually all membrane proteins are glycoproteins
cholesterol and glycolipids are found in lesser amounts

Front 7

Frame work of the plasma membrane (lipid bilayer)

Back 7

two back to back layers made up of phospholipids, cholestrerol and glycolipids

Front 8

glycoproetins

Back 8

integral-extends into or through the lipid bilayer
peripheral proteins are losely attached to the external or internal surface of the membrane

Front 9

Property of the plasma membrane

Back 9

selective permaeability

Front 10

selective permaeability

Back 10

permeable to water, fatty acids, fat soluble vitaminds steriods oxygen and carbondioxide

Front 11

what is the plasma membrane not permeable to?

Back 11

ions and charged or polar molecules (glucose and amino acids)

Front 12

cytoplasm

Back 12

site of all intracellular activites except those occuring in the nucleus

Front 13

cytosol

Back 13

medium in which many of the cell;s chemical reactions occur

Front 14

cytolskeleton

Back 14

maintains shape and gernal organization of cellular content; responsible for cell movements

Front 15

microfilaments

Back 15

contribute ot he cells strength and shape

Front 16

microvilli

Back 16

fingerlike progections of the plasma membrane (absorbtion)

Front 17

intermediate filaments

Back 17

found in cells dubject to tension and help hold organelles in place

Front 18

microtubules

Back 18

help determine cell shape and function in both the movement of organells

Front 19

centrosome

Back 19

centrioles is nine cluster of three microtublules surrounding it ais the pericontriolar material containing hundres of ring shaped proteins called tubuins

Front 20

tubulins

Back 20

organizing venter for growth of the mitotic spindle

Front 21

cilia

Back 21

move fluids over a cells surgace

Front 22

flagellum

Back 22

moves on entire cell

Front 23

ribosome

Back 23

protein synthesis

Front 24

endoplasmic reticulum

Back 24

rough er is the site of synthesis of glycoproteins and phosopholips

Front 25

smooth er

Back 25

site of fatty acids and steriods synthesis

Front 26

golgi complex

Back 26

accepts proteins forom rough er forms glycoproteins and liporoteins stores packages and exports proteins

Front 27

lysosome

Back 27

digests worn out organells entrie cells and extracellular material

Front 28

perosisome

Back 28

detoxifies harmful substances

Front 29

mitochondrion

Back 29

site of reaction that produce more of a cell's atp

Front 30

nucleus

Back 30

contains genes which control cellular structure and direct most cellular activites

Front 31

active transport

Back 31

see notes

Front 32

passive transport

Back 32
