What are the three parts to cell theory?
1.All living things are made of cells
2.Cells are the basic unit of life
3.All cells come from pre-existing cells
100
Do plant cells have mitochondria?
Yea
100
What are the three types of passive transport?
Simple diffusion, Facilitated diffusion, & Osmosis
200
Which microscope type can only be used if the specimen is not living (dead)?
Transmission Electron Microscope
Scanning Electron Microscope
200
What are the 2 MAJOR roles of lipids in a cell?
Long term energy storage and creates the cell membrane
200
What is the cell membrane made of?
Phospholipid bilayer and protein channels
300
Which microscope type would be best fit to look at a living sample of something really small collected from pond water?
Compound light microscope
300
What are the 3 major differences between plant and animal cells?
Plants have chloroplasts, cell walls, and a larger vacuole
Also, plant cells are fixed shape and animal cells have irregular shape
300
What is a difference between facilitated diffusion and active transport?
Active transport uses ATP and moves substances against the concentration gradient
Facilitated diffusion does not require ATP and moves substances with the concentration gradient
400
Scientists have can create new tissue from a patient's own stem cells. Which principle of the cell theory supports this research?
Cells come from pre-existing cells.
400
Why is the vacuole larger in plant cells?
To store more and exert pressure onto the cell wall to provide structural support
400
Give an example of passive transport
Water molecules entering a cell through the pores in the membrane
500
Explain how the cell theory was developed
The cell theory is a well-tested explanation of observations and is a culmination of the contributions of several different scientists
500
Which structure is found in animal cells, plant cells, and prokaryotic cells?
Ribosomes

The molecule is made-up entirely of carbon, hydrogen, and oxygen and is a source of energy. Which group of macromolecules would it belong to?
Carbohydrates
