Agenda 07/09/2010 Day 11 Data Con’t Energy Transfer –How get in/out of cell –Photosynthesi s and Respiration New Vocab Study Guide for Test!
3
How Do things get in/out of cell? We are going to add a saltwater plant into fresh water. What is going to happen to the cells? Why? Steps 1.Create a wet-mount slide with a Micro piece of plant using TANK water. 2.Set, focus, at 5X and 10X 3.Set, focus, SKETCH at 40X 4.Reset and clean slide 5.Create a wet-mount with a Micro piece of plant using TAP water 6.Set, focus, at 5X and 10X 7.Set, focus, SKETCH at 40X
4
How things get in? Diffusion: – the tendency of molecules to move from areas of high concentration to areas of low concentration (across cell membrane) Concentration: – how many molecules are in a given space Solute: – the dissolving substance within a solution – Salt or Water??
5
Which is high concentration and which is low? = a molecule High ConcentrationLow Concentration
6
Which direction will the molecules move?
7
This random motion results in predictable movement The molecules always move from areas of… to areas of… High Concentration Low Concentration
8
Osmosis Movement of water from concentration to concentration (across cell membrane). Movement of anything else?
9
Do you really know Passive Transport? Tape down in today’s notes What is going to happen in each case?
10
What happened in our lab? Saltwater plant add freshwater to? Freshwater plant add salt to?

Energy Transfer Photosynthesis Occurs in Autotrophs Chloroplast Chlorophyll Sunlight Glucose Reactants: 6CO 2, 6H 2 O, Sunlight Products: 6O 2, C 6 H 12 O 2 Respiration Occurs in Autotrophs and Heterotrphs Mitochondria Glucose usable Energy Reactants: 6O 2, C 6 H 12 O 2 Products: 6CO 2, 6H 2 O, usable Energy
12
Chemical Reactions 6CO 2 + 6H 2 O + Sunlight 6O 2 + C 6 H 12 O 2 6O 2 + C 6 H 12 O 2 6CO 2 + 6H 2 O + Useable Energy

Draw it out!
