CellsThe Basic Units of Life
Cell History Cell - the smallest unit that canperform all the processes needed forlife. Robert Hooke – built a microscope to see small things inhis lab– 1665: looked at a thin slice of cork Named the small sections “cells”
Cell TheoryRules For Cells1. All organisms are made of one ormore cells2. The cell is the basic unit of all livingthings3. All cells come from existing cells
Cell Size Most cells are too small to beseen without a microscope– It would take 50 human cells tocover the dot on the letter i in atextbook. Large Cells:chicken egg yolk is one cell!

Two Different Types of CellsProkaryotic Cells Means “before a nucleus” Kingdom Monera Can live in extremeenvironments Live off many differentenergy sourcesEukaryotic Cells Means “true nucleus” Kingdoms Protista, Fungi,Plantae & Animalia DNA is contained in thenucleus
Common Parts of A Cell Cells come in many shapes and sizes,but all cells have these in common:– Cell Membrane (barrier)– Cytoplasm (“juice” in the center)– Organelles (little organs with specific jobs)– Genetic Material (DNA or RNA)
Who looked into a microscopeand saw the first cell?1.2.3.4.James WatsonRobert HookeCharles DarwinGregor Mendel
Prokaryotic Cells Up Close No nucleus Have DNA Example: Bacteria– Tiny organisms that live almost everywhere In soil & water On/inside another living thing– Some are helpful (probiotic lactobacillus)– Others are harmful (streptococcus)

Prokaryotic Organelles4.Ribosomes1. Plasma membrane- Makes proteins– Encloses the cell- Located in cytoplasm– Regulates materialinto and out of cell5.Nucleoid2. Cell Wall- Contains hereditary– Supports cell andmaterial (DNA) of the celldetermines its shape- Located in cytoplasm3. Cytoplasm– A liquid material thatparticles aresuspended in
Eukaryotic Cells Up Close Have a nucleus that holds the DNA Two Types of Eukaryotic Cells:– Animal Cells– Plant Cells
Ribosome(yellow)VacuoleAnimal Cell crotubules
Animal Cell Organelle Jobs1. Lysosome – Breaksdown Food2. Cell membrane –Allows materials toenter and exit3. Nucleus – Controls allcell activities4. Nuclear Membrane –Protects the Nucleus5. Mitochondria –MakesEnergy(ATP)6. Endoplasmic ReticulumTransports Proteins7. Microtubules- ProvidesShape and structure8. Ribosomes – Make Proteins9.Vacuole – Stores food, wasteand water10. Cytoplasm – Fluid formovement

Willis Mountain, Virginia --- a Monadnock of Mineral Specimens by Dave Lines From our Field Trip info sheet, we learned that Willis Mountain is a "monadnock" --- pronounced "mo-nad-nok" --- a hill or mountain of resistant rock surmounting the surrounding plain. The Trip Sheet stated: "The kyanite exposure at Willis Mountain

How are organisms organized? Many-celled organisms are organized in cells, tissues, organs, and organ systems. Cells: Animals and plants are many-celled organisms. Animals are made up of many kinds of cells. You are made of blood cells, bone cells, skin cells, and many others. A plant also has different cells in its roots, stems, and leaves.
Cells are the fundamental unit of life (the basic unit of organization). All organisms are composed of cells. All cells come from preexisting cells. Common Characteristics Of Cells Cells must obtain and process energy Cells convert genetic in
