Cell OrganellesCell Organelles

1. All living things are made of cells

2. The cell is the basic structural and functional unit of life.

3. All cells come from pre-existing cells.

Cell Theory

Prokaryote vs Eukaryote

v.s.

Protists

Prokaryotes

Simple and small cells

Bacteria Cells!!!Unicellular (is a

single celled organism)

Prokaryotes

No Nucleus

Cell Wall

Cell Membrane

Cytoplasm

DNA in one big loop floating around.

Ribosomes: For building proteins

OMG SO SMALL

These are prokaryote E. coli bacteria on the head of a pin.

Eukaryotes

Animal Cells, Plant Cells, and Protists

Has a Nucleus Chromosomes (DNA)

inside of the nucleusMembrane-bound

organelles (Cell WallCell Membrane, Cytoplasm, Ribosomes, etc.)

Bigger and more complicated than prokaryotes

Cell MembraneProtects the cell and controls what enters

and leaves the cellMade of phospholipid (and protein channels)In ALL cells

Protein

Phospholipid

Cell WallLocated outside of

the cell membrane of plant cells and bacterial cells

Protects the cell and keeps plant cells from bursting

Made of cellulose (carbohydrate)

NucleusDirects all cellular

activitiesContains DNA

Which type of cells have this again?

RibosomeSite of protein

synthesis (place where proteins are made)

In ALL cells

That looks familiar…what is a That looks familiar…what is a polypeptidepolypeptide??

MitochondriaConverts and

releases energy for the cell to use

Site of Cellular Respiration

ChloroplastCaptures solar

energy and converts it into usable energy

Site of photosynthesis

Gel-like substance that organelles are suspended in.

Found in everything.

Cytoplasm
