Discovery/Theory
This was the first person to observe and name cells.
Who is Robert Hooke?
Organisms whose cells have a nucleus and other membrane bound organelles are called...
Eukaryotes
These objects are used by microscopes to focus light or electrons in order to magnify objects being observed.
What are lenses?
makes proteins
ribosomes
green organelle found only in plants and algae
chloroplast
This was the first person so observe living cells, connecting cells with life!
Who is Anton van Leeuwenhoek?
Bacteria do not have a nucleus or other membrane bound organelles and are called _______________ because of this.
prokaryotes
three microscopes used today
light, sem, tem
makes ribosomes
nucleolus
large organelle filled with water in plants
central vacuole
Cell theory, unlike spontaneous generation before it, says that cells come from...
What are pre-existing cells?
ALL CELLS have an outer boundary called the...
cell membrane
Who creates the first microscope
Van Le
modifies and packages proteins
golgi bodies
Series of tubes and sacs,
ER/endoplasmic reticulum
These high-powered microscopes show great detail of the surface of a sample
What are scanning electron microscopes or (SEM)
ALL cells contain a gel like fluid called the ________________
cytoplasm
If you wanted to see the surface of a cell you would use a
Scanning Electron Microscope
produce lipids (be specific)
smooth ER
short and numerous projections on the outside of a cell
cilia
These microscopes are what we use in class
What are Compound Light Microscopes?
The cell membrane only allows certain things to cross it, a property called...
selective/semi permeability
who created the first microscope and in what year
antony van leewenhoek, 1590
provide internal structure
cytoskeleton/microtubules/microfilaments
rod shaped
mitochondria
