The major difference between prokaryotic and eukaryotic cells
What are (membrane bound) organelles?
100
This characteristic means that the cell membrane identifies and transports materials in and out of the cell
What is selectively permeable?
100
Organisms that make their own food by using energy from the sun
What are autotrophs?
100
The types of cells that cellular respiration occurs in
What is animal, plant and bacterial cells?
100
A process that changes, or transforms, one set of chemicals into another
What is a chemical reaction?
200
The organelle in eukaryotic cells that controls the cell's activities
What is the nucleus?
200
The random movement of molecules from areas of high concentration to low concentration
What is diffusion?
200
The organelle that allows certain types of cells to carry out photosynthesis
What are chloroplasts?
200
The organelle in the cell where most of the reactions of cellular respiration occur
What is the mitochondria?
200
The energy that is needed to get a reaction going
What is activation energy?
300
The organelle that is often called the "powerhouse" of the cell and is where cellular respiration occurs
What is the mitochondria?
300
What would happen to your blood cells if they were placed in 100% fresh water
What is an increase in size/mass/diameter of the cell?
300
The reactants of photosynthesis
What is carbon dioxide and water?
300
The reactants of cellular respiration
What is oxygen and sugars (like glucose)?
300
The reactants of enzyme-catalyzed reactions
What is a substrate?
400
This selectively permeable organelle is responsible for maintaining a stable internal environment in the cell
What is the cell membrane?
400
This type of cellular transport is important because it uses cellular energy to bring in larger molecules and transport molecules against their concentration gradient
What is active transport?
400
The part of the cell that is responsible for capturing energy from the sunlight and is found in the chloroplasts
What is chlorophyll (or pigments)?
400
The products of cellular respiration
What is carbon dioxide, water and energy?
400
Changing this can affect enzyme activity because the shape of the enzyme is altered
What is temperature, pH and/or regulatory molecules?
500
These two organelles are found only in eukaryotic plant cells and NOT in animal cells
What are chloroplasts and the cell wall?
500
This is the specific type of cellular transport that brings water into plant cells through special protein channels
What is osmosis?
500
The products of photosynthesis
What is oxygen and glucose?
500
The chemical equation for cellular respiration
What is O2 + C6H12O6 --> CO2 + H2O + Energy?
500
The fit between these two things is often referred to as a "lock-and-key" fit because of their complementary shapes
