Osmosis is a form of ________transport. • passive
List 2 ways in which plant and animal cells are structurally different. • Animals cell = many vacuoles, Centrioles and Lysosomes • Plant cell= large water vacuole, chloroplast, cell wall
What part of a phospholipid would be touching water? • Phosphate head
What type of cells are plant and animal cells? • Eukaryotic Cells
Organelle: Site of chemical reactions; holds organelles • cytoplasm
Identify: • Mitochondria
The movement of materials across the plasma membrane by the use of transport proteins is called____________________. • Facilitated diffusion
Organelle: Contains digestive enzymes that break down molecules • Lysosomes
Suppose a ribosome attached to the rough ER made a protein. Where will it go next? • Golgi body
List one difference between eukaryotic and prokaryotic cells. • Prokaryotic cells = no nucleus; no membrane bound organelles • Eukaryotic cells = nucleus; have membrane bound organelles
The plasma membrane of the cell is specific in what is allowed to enter and exit the cell. This is an example of_________________. • Selectively permeable or • Semi-permeable
A function of chloroplasts would be ____________________. • Photosynthesis
Identify: • Water Vacuole
When food is pushed out of the paramecium, (one celled protist) this process is called______. • Exocytosis
What part of a phospholipid would be NOT be touching water? • Fatty Acid Tails
This macromolecule is found among the phospholipids and helps prevent the fatty acid tails from sticking together. • Cholesterol
Identify: • Nucleolus
Which scientist came up with the word “cell” based on the cells where monks lived? • Robert Hooke
The pressure that exists inside a plant cell when it swells is _________ pressure • turgor
What part of the phospholipid would be touching water? • Phosphate head
What is the significance of all the folds in the mitochondria? • The folds increase the surface area so this small organelle can make a lot of energy

Organelle: Provides support for plant cells • Cell Wall
Osmosis does not occur when a cell is placed into a(n) _______ solution • isotonic
Why does active transport use cellular energy? • Active transports moves molecules from an area of LOW to HIGH concentration (against the concentration gradient)
Identify: • Chloroplast

What type of active transport is used to remove wastes and mucus from a cell? • Exocytosis
How are the mitochondria and chloroplast similar? • Both help make energy
