IntroductionIntroduction
All living things are made of cellsCells are made up of organelles which are
structured to perform specific jobs neededfor life: cells are basic units of structureand functions of lifeCells always originate from other cells,
however the first cells are thought to haveformed from organic chemicals present inthe harsh conditions of early earth.

AgendaAgendaLearning about the parts of the cell:
Tonight: Read chapter 4 in science textCells and Heredity, p 73-87 for homework.
Focus in on section 4.2 Objectives
You should be able to:Describe the structure of a cell
Explain the functions of the cells organellesCompare and contrast plant and animal cellsConstruct a table that shows understanding of cellfunctions and structure
..By next week!

OverviewOverview Tools we will use to learn aboutTools we will use to learn aboutcells:cells:
You will read the textbook You will complete an Online activity in a thoughtful way inorder to begin to memorize the parts of a cell and the functions
of those partsYou will prepare and study from Flashcards prepared withnames of parts on one side and functions on the other You will prepare a model that demonstrate the location of organelles of a cell and the differences between plant and animal
cells.You will test your knowledge of the information by completingthe chapter review located on pages 89-91You will relearn missed information as needed

Cell- The basic unit of structure andfunction in living things
Organelle: a tiny part of a cell which has aspecial form and functionTissue: a group of cells working together to perform a life function
Organ: a group of tissues working together to form a life functionOrganism: A LIVING THING

Cell Wall: the skeleton of Cell Wall: the skeleton of
plantsplantsOnly found around theoutside of Plant cellsStructure: Made of a
complex fibrouscarbohydrate calledCELLULOSEStructure: Dense,strong
Function: Keeps plantcells upright andprotects them fromDrying

Cell Membrane:Cell Membrane:
thegatekeeperthegatekeeperStructure: doublelayer of lipid moleculeswith proteins amongthe lipidsFunction: It protectsinside of cell fromenvironment andcontrols what can enteror leave the cell.the gatekeepermeansit allows some thingsin/out, but not others

Nucleus: the control centerNucleus: the control centerStructure: Its contents arecontained by the nuclearmembraneStructure: large dark stainingareaFunction: ContainsChromosomes, which are madeoff DNA (deoxyribonucleicacid). DNA contains theinformation about how the cellcan construct the proteinsneeded by that organism.Function: Messenger RNA(ribonucleic acid), located inthe nucleus, will copy parts of the DNA ,as needed, then travelout of the nucleus to where aprotein is to be made.

placeplaceStructure: consistencyof hair gelStructure: made mostlyof water Function: the location of many chemical reactionsand organelles in cells
Function: stuffing for cells (fills up volume of cell membrane bag)

Plants:
Have plastids:CHLOROPLASTS
Have cell walls
Have 1-2 largevacuoles
Animals
Have centrioles
Have many

Need to make theirown food by theprocess of PHOTOSYNTHESISHave to be able toaccess sunlight to
make food-cell wallsand hydrostaticpressure of cytoplasm help holdthem upright
AnimalsNeed to captureand ingest orabsorb foodparticles
Centrioles areinvolved in celldivision
