What makes them function???
The basic unit of an organism Cells What makes them function???

Organelles & Functions
Organelles are structures in cells that carry out specific functions Cell membrane – (SECURITY GUARD) protects the cell, controls what comes in and out of the cell Nucleus – (CONTROL CENTER) directs cell activities ER (Endoplasmic Reticulum) – (HIGHWAY) sends messages to golgi body, and it is where some ribosomes are found(Smooth ER(no ribosomes)/Rough ER(ribosomes) Golgi Apparatus (Golgi Body) – (MAILMAN) packages proteins to be delivered around the cell
3
Organelles & Functions
Ribosome - makes proteins Mitochondria – (POWER HOUSE) breaks down food & produces energy Lysosomes- (GARBAGE MEN) clean/remove wastes Vacuoles- (WAREHOUSE) stores molecules food, H2O, and O2 Cytoplasm- jelly-like substance inside the cell --holds all organelles inside the cell
4
Prokaryotic Cell vs. Eukaryotic Cell
Prokaryotic Cell: does NOT have a nucleus or other membrane-bound organelles most are unicellular such as bacteria Eukaryotic Cell: HAS a nucleus and other membrane-bound organelles Most multicellular organisms and some unicellular *Both types of cells have cytoplasm, DNA, and a cell membrane *Animal & Plant cells are EUKARYOTIC CELLS!
5
PLANT CELLS HAVE 2 ORGANELLES THAT AN ANIMAL CELL DOES NOT:
REMEMBER! PLANT CELLS HAVE 2 ORGANELLES THAT AN ANIMAL CELL DOES NOT: Cell Wall: strong rigid layer outside of the cell membrane Chloroplasts: absorbs light energy and converts it into chemical energy (glucose) Central Vacuole: one large storage organelle for water and other materials (only some animal cells have vacuoles and are much smaller!)
6
MVCO: Due 2/6/18 Example: Claim: Which is the most valuable? Specify the cell Evidence: What is its role/job? How does it affect the entire cell? Reasoning: Why is this evidence so important? Materials: white drawing paper One index card Rubric-see graphic organizer USE YOUR NOTES and ONLINE RESOURCES TO REFER TO ORGANELLES AND FUNCTIONS
