Life at the Cellular Level Flashcards
Who was the first human to observe living microorganisms through a microscope?
Anton von Leeuwenhoek
What scientist observed cork through a microscope and called them cells
Robert Hooke
What scientist studied plants and helped create the cell theory?
Matthias Schleiden
What scientist studied animals and helped create the cell theory?
Theodor Schwann
What scientist concluded that all cells come from pre-existing cells
Rudolph Virchow
What type of cell has no nucleus?
Prokaryote (Pro rhymes with No)
What type of cell does have a nucleus?
Eukaryote (Eu rhymes with Do)
What organelle is called the brain or control center?
Nucleus (Nerd)
What organelle is found within the nucleus and helps make proteins?
Nucleolus
What nucleus actually makes the proteins?
Ribosomes (Master of meat-The chef)
What is the cell’s passageway?
Endoplasmic Reticulum (ER) The doctor that reminded us that we need to know the highway that gets us to the ER.
What is the organelle that acts like a mailroom by receiving and then sending out materials
Golgi Bodies (There are a lot of bodies in the mailroom)
What organelle stores chemicals used for breaking down dead cell parts?
Lysosomes (Remember the actor in the toilet spraying Lysol)
What is the organelle that is used for storage (Large in plants smaller in animals)
Vacuole (Hobo coming out of the closet)
What is the powerhouse of the cell?
Mitochondria (Blue suited basketball ladies with strange muscles)
This organelle is found only in plants and it provides the cell with structure and protection?
Cell Wall (Sheriff/Cowboy)
What organelle is found only in animal cells and it helps with cell division?
centrioles
This organelle is a jelly like substance that other organelles float around in and gives the cell dimension.
Cytoplasm (Jelly Kelly the rap star)
The organelle is “selectively permeable”> This means that it only lets certain materials go in and out.
Cell Membrane (Gatekeeper/Grim Reaper)
This is the organelle where photosynthesis occurs. It is filled with chlorophyll.
Chloroplasts
This is the organelle where cellular respiration occurs.
Mitochondria
Which type of “transport” requires energy?
Active Transport (going up the hill from low to high)
Which type of transport does NOT require energy?
Passive Transport (movement from High C to Low C)
What process causes the movement of molecules from an area of high concentration an area of low concentration?
Diffusion
What is the special kind of diffusion that involves water molecules?
Osmosis
What type of molecule speeds up chemical reactions? (Speedy gonzalez)
Enzyme
