CELLS
Cells are the basic units of function in all living things.
Cells in animals and plants have unique forms that allow each to take part in processes that are necessary for the cell and or/living thing to survive.
“Small organ”
Carry out tasks for cell Brings in food suppliesGet rid of wasteRepair the cell
WHAT IS AN ORGANELLE?
Function: Holds the cell together and lets substances in and out (Semi-permeable)
Outer Layer of cell
CELL MEMBRANE “The Bouncer”
Function: DNA is stored or held
Directs cell’s activities
Nucleolus: dark spot in the middle of the nucleus that help make ribosomes
NUCLEUS “The Brain or the Boss”
Function: Energy formation Breaks down food to make ATP
ATP: major fuel for all cell activities that require energy
MITOCHONDRION “The Power House”
Function: Makes protein
Can be on Endoplasmic Reticulum or free in cytoplasm
RIBOSOMES “Builders/Workers”
Function: Processing and packaging center
Packages macromolecules, like protein and lipids as they are made in the cell To be packaged & storedUsed to send them out of the cell
GOLGI APPARATUS “UPS”
ENDOPLASMIC RETICULUM “Roads”
Function: A membrane system of canals and tunnels that transport materials
Rough ER: covered with ribosomesSmooth ER: pathway for molecules to move throughout the cell
Functions:
1. breaks down food
2. destroys old or worn out cell parts
3. Engulfs viruses or bacteria
LYSOSOME “Garbage Can”
Function: Gives the cell a rigid shape (Structure and Support)
Outer layer of plant cells
CELL WALL “Protector”
Contain chlorophyll, a green chemical needed for photosynthesis. Turns energy from the sun into nutrients
(food)
CHLOROPLASTS
Function: Stores waste, water, and food
Plant cell Vacuoles are bigger than those in animal cells!
Vacuole “Storage Tank”
