1
LOOKING INSIDE CELLS CH 3 SEC 2
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
3
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
4
ANIMAL CELL DEFINE 2
5
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.
6
PLANT CELL DEFINE 2
7
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
8
CELL MEMBRANE SKETCH
9
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
10
NUCLEUS SKETCH
11
ORGANELLES IN THE CYTOPLASM
CYTOPLASM- IS THE REGION BETWEEN THE CELL MEMBRANE AND THE NUCLEUS KEY- IT IS A CLEAR, THICK, GEL-LIKE FLUID. SKETCH
12
CYTOPLASM KEY- IN THE CYTOPLASM ARE MANY ORGANELLES. EACH OF THESE CARRY OUT A SPECIFIC FUNCTION IN THE CELL.
13
ORGANELLES list and number in abc order
14
ORGANELLES AND THEIR FUNCTION
MITOCHONDRIA- ROD SHAPED STRUCTURES THAT ARE KNOWN AS THE “POWERHOUSES'’ OF THE CELLS. KEY- RELEASE THE CELLS ENERGY SKETCH
15
ENDOPLASMIC RETICULUM- MAZE OF PASSAGEWAYS THAT HELP FORM PROTEINS AND CARRY MATERIALS THROUGHOUT THE CELL SKETCH
16
RIBOSOMES- PRODUCE PROTEINS ON THE WALLS OF THE E. R
RIBOSOMES- PRODUCE PROTEINS ON THE WALLS OF THE E.R. AND IN THE CYTOPLASM SKETCH
17
ORGANELLES CONT’D GOLGI BODIES- CELLS MAIL ROOM. THEY PACKAGE AND DISTRIBUTE MATERIALS THROUGHOUT THE CELL AND THEY RELEASE WASTE. SKETCH
18
KEY- PLANT CELLS ONLY CHLOROPLAST- FOUND IN PLANT CELLS ONLY. CAPTURE ENERGY FROM SUNLIGHT AND MAKE FOOD EXAMPLE GREEN LEAVES
19
VACUOLES- STORAGE AREA FOR CELLS
VACUOLES- STORAGE AREA FOR CELLS. THEY STORE FOOD AND OTHER MATERIALS NEEDED BY THE CELL. KEY- MOST PLANT CELLS HAVE ONE LARGE VACUOLE FOR WATER. SKETCH
20
ORGANELLES CONT’D LYSOSOMES- ARE SMALL ROUND STRUCTURES CONTAINING CHEMICALS THAT BREAK DOWN CERTAIN MATERIALS INTO SMALLER ONES. CELLS CLEANUP CREW. SKETCH
21
CELL DIVERSITY KEY-CELLS COME IN MANY SHAPES AND SIZES DEPENDENT ON THEIR FUNCTION.
