Membrane Transport
What are the two types of membrane transport?
Active and passive
What is the second phase of a tree's lifecycle?
Sprout
In which organelles does photosynthesis occur?
Chloroplasts
Mitochondria
What two football teams always play on Thanksgiving?
Cowboys and Lions
What is the difference between active and passive transport?
Active requires energy while passive does not
What is the difference between xylem and phloem?
xylem -> one way transport
phloem -> two way transport
What are the two major steps of photosynthesis?
1. Chorophyll (in chloroplasts) absorb sunlight
2. Chloroplasts use sun energy and react CO2 with H2O to form glucose (and oxygen)
Why do animals not need to photosynthesize?
Because we get our sugars from consuming foods
What war was ended by the signing of the Treaty of Versailles
World War I
What are the three types of solutions when it comes to osmosis? Describe each.
Hypertonic -> water flows out of cell -> shrink
Isotonic -> water flows in and out of cell -> normal
Hypotonic -> water flows into cell -> swell
What are stomata?
Pores on bottom side of leaf that absorb carbon dioxide and expel water
What is the chemical reaction for photosynthesis?
Sunlight
6H2O + 6CO2 -------> C6H12O6 + 6O2
What is the chemical reaction for cellular respiration?
C6H12O6 + 6O2 -> 6H2O + 6CO2 + ATP
What is the largest country in the world?
Russia
What are the two types of passive transport? Describe each.
Simple -> molecules travel unassisted through cell high to low concentration
Facilitated -> Transport proteins carry larger molecules (and more molecules) in/out of membrane
Cohesion -> water molecules attract together via charges
Adhesion-> water molecules attract to other molecules (cell walls of xylem/phloem)
Why do plants need carbon dioxide?
Because without it, plants could not produce sugars.
Why do animals need oxygen to survive?
Because oxygen is a major reactant in cellular respiration which gives us the energy we need to complete all life processes
What is the national animal of Scotland?
The unicorn
Define solute, solvent, and solution
Solute: Substance dissolved in another substance (ex: salt)
Solvent: Liquid that dissolves the solute (ex: water)
Solution: The combination of a solvent and solute
What is the name of the dip in water when in a container? (i.e. the name for why water is not flat in a container). Why does this happen?
meniscus
Adhesion pulls water molecules up walls of container.
Why do plants need both photosynthesis AND cellular respiration?
Photo -> produces sugar (not yet usable)
CR -> convert sugar to ATP (usable energy)
Describe where ATP is produced
1. When glucose is broken down into smaller sugar molecules, a little ATP is produced
2. Smaller sugar molecules react with oxygen in mitochondria producing a large amount of ATP
How many Great Lakes are there? Name them
5. Eerie, Huron, Michigan, Ontario, Superior
