What is this organelle? What does it do? Cell membrane – controls what goes in and out of the cell
What organelle is pictured? What does it do? Golgi Body – packages and transports proteins in vesicles
What organelle is this? The membrane around it The dark center The squiggly lines Nucleus Nuclear envelope (membrane) Nucleolus DNA
What organelle is this? What does it do? Mitochondria – powerhouse of the cell
What organelle is this? What does it do? What kind of cells have them? Chloroplast – converts sunlight into glucose (food)
What organelle is this? What does it do? Ribosome – reads DNA to make proteins
What type of cells are these? (generally speaking)

What type of cells are these? (generally speaking)
What organelle: Stores and transports proteins throughout the cell? Endoplasmic reticulum (specifically the SER)
What organelle: Makes ribosomes? Nucleolus
What organelle: Controls eating, movement, and reproduction in the cell? Nucleus
What organelle: Conducts electricity within the cell? Cytoplasm
What organelle: Converts sunlight into a useable energy source? Chloroplast
What organelle: Facilitates movement of materials inside the cell? Cytoplasm
What organelle: Makes and transports proteins throughout cell? Endoplasmic reticulum (specifically RER)
What organelle: Provides structure to the cell? Cytoskeleton Hint: it’s found inside the cytoplasm Cytoskeleton
What organelle: Reads DNA to make proteins? Ribosomes
What organelle: Sends vesicles to plasma membrane? Golgi body
What organelle: Transports materials in, out, and within the cell by use of vesicles? Golgi body
What organelle: Stores nutrients and/or wastes? Vacuoles
What organelle: Breaks up waste and debris with enzymes? Lysosomes
What organelle: Gives plant cells rigidity and strength? Cell wall
What organelle: Converts food and oxygen into ATP? Mitochondria
What is osmosis? The diffusion of water across a membrane.
What is diffusion? The tendency of molecules to spread evenly from areas of high concentration to areas of low concentration WITHOUT using energy.
What happens when: An animal cell is exposed to a hypertonic solution? Shrivels up (corn syrup egg) A plant cell is exposed to a hypertonic solution? Cell membrane pulls away from cell wall An animal cell is exposed to a hypotonic solution? Swells (vinegar or green tap water) A plant cell is exposed to a hypotonic solution? Swells slightly A plant or animal cell is exposed to an isotonic solution? Water goes in and out of cell equally
