PRESENTATION OUTLINE
CELL STRUCTURE
Plasma Membrane
Function:
A PHOSPHOLIPID BILAYER; CONTROLS MOVEMENT OF MATERIAL IN AND OUT OF THE CELL
Where:
PROKARYOTIC AND EUKARYOTIC CELLS; BOTH PLANT AND ANIMAL CELLS
ANALOGY:
IIT'S LIKE AN ENVELOPE BECAUSE IT HOLDS THINGS TOGETHER BUT DOES NOT GIVE MUCH PROTECTION

Cell Wall
FUNCTION:
A rigid structure outside of the plasma membrane
Where:
BOTH PROKARYOTIC AND EUKARYOTIC CELL; PLANTS, BACTERIAS, AND FUNGUS
Analogy:
IT IS LIKE A STRAINER BECAUSE IT HOLDS THE NOODLES IN BUT IT STILL HAS HOLES TO LET THE JUICE OUT

CYTOPLASM
Function:
JELLY-LIKE FILLING; SUPPORTS THE ORGANELLES AND CONTAINS NUTRIENTS
WHERE:
BOTH PROKARYOTIC AND EUKARYOTIC CELLS; BOTH PLANT AND ANIMAL CELLS
ANALOGY:
IT IS LIKE THE INSIDE OF A JELLY DOUGHNUT BECAUSE IT FILLS UP THE INSIDE AND KEEPS EVERYTING IN PLACE

Nucleus:
Function:
DIRECTS ALL CELL ACTIVITY; CONTAINS CHROMATIN (THIN CHROMOSOMES) AND A NUCLEUS (MAKES THE RIBOSOMES)
WHERE:
EUKARYOTIC CELLS; BOTH PLANT AND ANIMAL CELLS
Analogy:
IT IS LIKE THE PRINCIPAL OF A SCHOOL, BECUASE IT TELLS THE TEACHERS WHAT TO DO

Endoplasmic Reticulum
FUNCTION:
A FOLDED MEMBRANE WHICH PROVIDES A LARGE SURFACE AREA ON WHICH RIBOSOMES SYNTHESIS PROTEINS
WHERE:
EUKARYOTIC CELL; BOTH PLANT AND ANIMAL CELLS
RIBOSOMES
Function:
MADE BY THE NUCLEOLUS; MOVE TO THE ER WHERE THEY MAKE PROTEINS
Where:
BOTH PROKARYOTIC AND EUKARYOTIC CELLS; BOTRH PLANT AND ANIMAL CELLS
Golgi Apparatus
Function:
FLATTENED SACS THAT RECEIVE PROTEINS, PACKAGES THEM, AND MOVES THE PROTEINS TO THE PLASMA MEMBRANE
Where:
EUKARYOTIC CELLS; BOTH PLANT AND ANIMAL CELLS
Analogy:
IT IS LIKE A PERSON THAT SENT OFF A PRESENT BECAUSE THEY PACKAGE IT AND GET THE PRESENT SENT OFF

VACUOLE
Function:
STORAGE OF FOOD, WATER, AND WASTE
WHERE:
Eukaryotic cell Plant cells have one large vacuole Animal cells have many small vacuoles
Analogy:
IT IS LIKE A JUNK DRAWER BECAUSE IT STORES WASTE AND THINGS NOT NEEDED AT THE TIME

CHLOROPLAST
Function:
TRANSFORMS LIGHT ENERGY INTO CHEMICAL ENERGY
Where:
EUKARYOTIC CELLS; ONLY FOUND IN PLANTS AND SOME BACTERIA
MITOCHONDRIA
Function:
STORES AND RELEASES ENERGY; "POWERHOUSE OF CELL"
WHere:
EUKARYOTIC CELLS; BOTH PLANT AND ANIMAL CELLS
Analogy:
IT IS LIKE A RUBBER BAND BECAUSE IT STORES ENERGY UNTIL THE CELL NEEDS IT AND IT IS RELEASED

LYSOSOMES
Function:
CONTAINS DIGESTIVE ENZYMES THAT DIGEST ALL WASTE AND THEN MOVE IT TO THE VACUOLE
Where:
EUKARYOTIC CELLS; ANIMAL CELLS
THE ENd
