Developing the Microscope
This dude was the first to identify the cell by looking at cork through his basic microscope
Who is Robert Hooke?
All cells come from ____ ______
What is "other cells" or "preexisting cells"?
These are basic cells that are missing organelles and a clearly defined nucleus
What are prokaryotic (prokaryotes)?
This major component of the plasma membrane keeps the membrane flexible/fluid
What is cholesterol?
A whip-like appendage on the surface of some cells, providing motility or moving fluids, acting like a propeller in bacteria (rotating) or a whip in eukaryotes (bending)
What is FLAGELLA/FLAGELLUM?
This type of microscope uses lenses and light to see an image
What is compound light microscope?
All living things are composed of ___.
What are "cells"?
TRUE or FALSE: Only eukaryotic cells have a plasma membrane.
What is FALSE? [All cells have a plasma membrane]
This is the model that describes the structure of the plasma membrane
What is the "Fluid Mosaic Model"?
Essential, double-membrane-bound organelles in most eukaryotic cells that generate most of the cell's supply of adenosine triphosphate (ATP), the energy currency, through cellular respiration, earning them the nickname "powerhouses of the cell"
What is MITOCHONDRIA?
This dude looked at the gunk on his teeth through his basic microscope to see moving parts he called animalcules
Who is Anton van Leeuwenhoek?
Cells are the basic units of _____ and _____ of living things.
What is "structure" and "function"?
These are the more complex cell type that has all organelles and a clearly defined and organized nucleus
What is eukaryotic (eukaryotes)?
This major component of the plasma membrane functions for chemical communication
What is CARBOHYDRATE?
These non-membranous structures consist of a large and a small subunit that come together to build proteins essential for nearly all cell functions
What are RIBOSOMES?
This type of microscope uses electron beams to magnify image/specimen
What is electron microscope?
The 2 dudes who were major developers of the cell theory
Who are Schleiden and Schwann?
All cells have ____ either organized in a nucleus or "loose" within the cell.
What is DNA?
This major component of the plasma membrane forms a double layer
What is PHOSPHOLIPID?
A distinct central organelle that contains the cell’s genetic material in the form of DNA
What is NUCLEUS?
The development of this object was the major factor in discovering the existence of the cell and the development of the cell theory
What is the microscope?
This dude came in and settled the dispute on where cells come from
Who is Virchow?
All cells require ____ to survive. So ALL cells must be able to break down materials to release this in usable form
What is ENERGY?
This characteristic of the plasma membrane supports the homeostasis of the cell by controlling what enters and exits
What is SELECTIVE PERMEABILITY?
Dark spot within nucleus that is the site for ribosome production
What is NUCLEOLUS?
