Structure that reults from atoms joined together by bonds
Molecule
What three scientists came up with the basis for cell theory?
Schwanna, Schleiden, Virchow

Theory
The golgi apparatus functions to _______.
(also known as: golgi complex, golgi body)
Package, sort, and ship materials INTO and OUT OF the cell
NOTE: it *does* *NOT* transport around the cell
How is a prokaryote different from a eukaryote?
Prokaryote - NO nucleus! Only found in bacteria! NO membrane bound organelles! OLDER. SMALLER.
Eukaryote - HAS a nucleus, has membrane bound organelles! BIGGER. Found in more complex organisms (ex. humans)
Magnify the image on a microscope
Objectives (4x, 10x, 40x)
Eye piece (10x)
Objective x Eyepiece = magnification
(ex. 4x objective x 10x eyepiece = 40 magnification)
What is the difference between quantitative and qualitative data/observations?
Quantitative - numbers
Qualitative - looks

Cell
Why does a scientist publish their work?
So that it can be reviewed, verified, and repeated over and over
Basic unit of matter
Atom
A group of different populations that live together in a defined area
Community
