Cell Theory
The scientist who observed a cork with a microscope and called the tiny boxes "cells"
Robert Hooke
Which microscope reads images 1000 times smaller than those of visible in light microscopes
Electron microscope
What macromolecules make up the cell membrane?
Lipid and protein
This organelle controls the cell
nucleus
This is the movement of water from a high concentration to a low concentration
osmosis
Scientist that stated all plants are made of cells
Matthias Schleiden
Scanning electron microscope
This layer makes up the cell membrane
phospholipid bilayer
This is the outer layer of an animal cell
cell membrane
During diffusion when the concentration of molecules of a membrane that is the same
isotonic
Scientist that stated all animals are composed of cells
Theodor Schwann
If looking under a microscope, how do you know you are looking at a prokaryotic cell?
lacks nucleus, membrane bound organelles
What is the function of the cell membrane?
Allows certain things into and out of the cell
This makes proteins
ribosomes
Why would an animal cell that is surrounded by freshwater burst?
the water moved into the cell
Scientist that stated all cells come from pre-existing cells
Rudolf Virchow
What microscope would you use to view live specimen?
Compound light microscope
The cell membrane is said to be
selectively permeable
This is used to break down lipids, carbohydrates and proteins into smaller molecules for the cell to use
lysosome
Why does diffusion occur? (reason not function)
molecules are constantly moving and colliding with each other
What are the parts of the cell theory?
1. All living things are made of cells
2. All cells come from other cells
3. Cells are the basic unit of structure and function in living things
What microscope would you use for dissections?
Stereoscopic microscope
This is used to help transport large molecules across the cell membrane
protein channel
This modifies, sorts and packages proteins and other materials for storage or release from cells
Golgi body/apparatus
What is the correct path of a protein in a cell?
ribosome, endoplasmic reticulum, golgi apparatus
