Cell Organelles
Inside a Cell Plant & Animals contain ORGANELLES Like organs in your body ... Each organelle has a different job to help keep the cell alive
Brain Pop Cells Cell Structures
Cell Membrane “The Bouncer” Lipid bi-layer, semi-permeable Separates cell from its environment All cells! *It says what Comes in and what goes out
Cell Wall Only in plant and most prokaryotic cells! Provide support and structure Suit of Armor
Nucleus Control center of cell ( the BRAIN) Controls reproduction & activities of cell Contains DNA Only plant and Animal cells!
Inside the Nucleus protects the nucleus makes RIBOSOMES Chromosomes Nuclear Membrane protects the nucleus Nucleolus makes RIBOSOMES Chromosomes contains DNA
Nuclear Membrane Double membrane surrounding nucleus Controls what goes through pores Selectively permeable
Endoplasmic Reticulum (ER) Transportation network of cell System of canals Like a HIGHWAY Proteins and other materials pass through Lipid synthesis Organelle assembly Plants and animals
2 Types of Highways Smooth ER Rough ER (1-26) = Fast No Ribosomes (Knob Creek Rd.) = Slow Contains Ribosomes
Ribosomes Makes Proteins Free or attached to ER All cells!
Lysosomes Cell Janitor cleans the cell Contains digestive enzymes to break down materials Animal cells
Golgi :Apparatus or Complex or Bodies Packaging structures Roll up proteins into membrane bound vesicles for export The Post Office or UPS Plant and Animal
Centrioles Aid in Reproduction of cell (mitosis) Only in animals!
Central Vacuole * Its like Tupperware! Compartments used for storage of H2O, food, & wastes Small or none in animals Large in plants * Its like Tupperware! Vacuole
Chloroplasts GLUCOSE Only in plants! Chlorophyll Photosynthesis Takes in Light to make GLUCOSE
Mitochondria Powerhouse or Battery of the cell Site of cellular respiration Breaks down glucose for ATP Double Membrane Plants and animals
Cilia Short hairlike structures used in locomotion & feeding in animals (single cells)
Flagella Long extensions of cell membrane used in locomotion Usually in prokaryotic
Pseudopodia Temporary projection of cytoplasm for MOVEMENT Amoebas Animal and prokaryotic
Cytoplasm its like Jell-O Jelly like fluid surrounding organelles Cell reactions take place here All cells!
Cytoskeleton Support Help maintain cell shape and structure Aid in movement ALL cells
What are the parts in a plant cell that aren’t in an animal cell? Chloroplast Large Vacuole Cell Wall
What is the difference between smooth & rough ER? What does the ER do? Smooth = No Ribosomes Rough = Ribosomes Transportation & Lipid Assembly
Why do plants need a cell wall & chloroplast and animal cells do not ?
Organelle Diagnosis You are the cell “doctor” From the conversation with your patients, jot down notes on their symptoms (what’s wrong) Diagnose their illness (which organelle is not functioning correctly)
Essential Question - What are the functions of the major cellular organelles? Pretend you are a cell. Write a quick story about how 6 of your organelles help you survive.
Label all of the organelles
Flashcards – for each organelle On the front Number the card Glue down the picture On the back Name of organelle Function of organelle Make a note if it’s only found in certain cell types
