Parts only found in plant????1. Chloroplast
• Absorbs light energy• Photosynthesis
occurs• Pigment/color!!
2. Cell Wall• Protection• Structure• Think: no skeleton!
3. Large Vacuole• Storage• WATER!!! –
structure

Cell Theory……• All Living
Things are made of Cells
• All cells come from other cells (previously existing)
![Page 22: Agenda 07/08/2010 Day 10 of photosynthesis lab Con’t Energy Transfer –Auto vs. Hetero Trophs –Eukaryotic Cell Organelles and Functions –Cell Theory –Anatomical](https://reader030.vdocuments.us/reader030/viewer/2022032606/56649e865503460f94b89cd1/html5/thumbnails/22.jpg)
So, what is a cell??• List the organization of an
organism from largest to smallest.
• tissue• organism• cell• organ• gene• organelle• chromosome• organ system

Traits Genes give us a PROTEIN (enzyme) that gives
us a trait Genes located in the Cell Cells 1 job produce an enzyme (protein) gives
trait in body
Traits can be… Anatomy (actual organs, hair, cartilage, “parts”) Physiology (chemicals that control the anatomy
Proteins!) Doctors biochemists
Blood test
Why Study?

Common Proteins and their Empirical Formulas…
Testosterone C19H28O2
Serotonin C10H1402N2
Adrenaline C8H11O3N
Glucose: C6H12O6
Cholesterol C27H45OH

Energy Transfer - Carbon and Oxygen Cycle Elements?
Compounds?
Molecules?
![Page 26: Agenda 07/08/2010 Day 10 of photosynthesis lab Con’t Energy Transfer –Auto vs. Hetero Trophs –Eukaryotic Cell Organelles and Functions –Cell Theory –Anatomical](https://reader030.vdocuments.us/reader030/viewer/2022032606/56649e865503460f94b89cd1/html5/thumbnails/26.jpg)
Reactions?? Take molecules, rearrange them to get something new!
Bonds between certain molecules are broken, separate atoms rearrange and bond to form different molecules What does this? ENZYMES!
Sometimes energy is required, other times energy is produced
Trick: Matter can never be created or destroyed!!
Equation? Just shown on paper

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?
Steps1. 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
