LOOKING INSIDE
CELLS
CH 3 SEC 2
PURPOSE
 - STUDENTS SHOULD KNOW THE
CHARACTERISTICS OF PLANT AND
ANIMALS CELL AND THEIR
DIFFERENCES
 STUDENTS SHOULD BE ABLE TO
NAME THE ORGANELLES AND THEIR
FUNCTIONS
WHAT IS INSIDE A CELL?
 KEY- THERE ARE EVEN SMALLER
STRUCTURES INSIDE CELLS CALLED
ORGANELLES
 ORGANELLES- CARRY OUT
SPECIFIC FUNCTIONS WITHIN
THE CELL JUST LIKE OUR
ORGANS- HEART, BRAIN, ETC

ANIMAL CELL
CELL ORGANELLE TOUR
 CELL WALL- IS A RIGID LAYER OF
NON-LIVING MATERIAL THAT
SURROUNDS THE CELLS OF
PLANTS
 KEY- THE CELL WALL HELPS
PROTECT AND SUPPORT THE
CELL.
PLANT CELL
CELL MEMBRANE
 KEY- ALL CELLS HAVE CELL
MEMBRANES IN THEIR OUTER LAYERS
 KEY- THE CELL MEMBRANE
CONTROLS WHAT SUBSTANCES COME
INTO AND OUT OF A CELL
 KEY- FOR A CELL TO SURVIVE THE CELL
MEMBRANE ALLOWS MATERIALS LIKE
FOOD AND WATER PASS THROUGH THE
MEMBRANE AND WASTE TO EXIT.
 EX- LIKE THE SCHOOL FENCE
CELL MEMBRANE
NUCLEUS
 NUCLEUS- ACTS AS THE CONTROL
CENTER OF THE CELL
 KEY- THE NUCLEUS DIRECTS ALL OF
THE CELLS ACTIVITIES
 EX- YOUR BRAIN
 KEY- THE NUCLEUS CONTAINS THE
CELLS GENETIC MATERIAL
NUCLEUS
ORGANELLES IN THE
CYTOPLASM
 CYTOPLASM- IS THE REGION
BETWEEN THE CELL MEMBRANE AND
THE NUCLEUS
 KEY- IT IS A CLEAR, THICK, GEL-LIKE
FLUID.

CYTOPLASM
 KEY- IN THE CYTOPLASM ARE MANY
ORGANELLES. EACH OF THESE
CARRY OUT A SPECIFIC FUNCTION IN
THE CELL.
ORGANELLES
ORGANELLES AND THEIR
FUNCTION
 MITOCHONDRIA- ROD SHAPED
STRUCTURES THAT ARE KNOWN AS
THE “POWERHOUSES'’ OF THE
CELLS.
 KEY- RELEASE THE
 CELLS ENERGY
 ENDOPLASMIC RETICULUM- MAZE
OF PASSAGEWAYS THAT HELP FORM
PROTEINS AND CARRY MATERIALS
THROUGHOUT THE CELL
 RIBOSOMES- PRODUCE PROTEINS
ON THE WALLS OF THE E.R. AND IN
THE CYTOPLASM
ORGANELLES CONT’D
 GOLGI BODIES- CELLS MAIL ROOM.
THEY PACKAGE AND DISTRIBUTE
MATERIALS THROUGHOUT THE CELL
AND THEY RELEASE WASTE.
 CHLOROPLAST- FOUND IN PLANT
CELLS ONLY. CAPTURE ENERGY
FROM SUNLIGHT AND MAKE FOOD
 GREEN LEAVES
 VACUOLES- STORAGE AREA FOR CELLS.
THEY STORE FOOD AND OTHER
MATERIALS NEEDED BY THE CELL. MOST
PLANT CELLS HAVE ONE LARGE VACUOLE
FOR WATER.
ORGANELLES CONT’D
 LYSOSOMES- ARE SMALL ROUND
STRUCTURES CONTAINING CHEMICALS
THAT BREAK DOWN CERTAIN MATERIALS
INTO SMALLER ONES. CELLS CLEANUP
CREW.
CELL DIVERSITY
 KEY-CELLS COME IN MANY SHAPES
AND SIZES DEPENDENT ON THEIR
FUNCTION.
