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 Organization– How do things get in/out of cell?
Types of Cells
Autotroph Heterotroph
Eukaryotic Cell Organelles and Functions
Energy through: Energy through:
All• • • • •
Only in Autotrophs• • •
Only in Heterotroph•
Cells and Energy Transfer – Biology book
Heterotroph:• Cell Membrane• Nucleus• Cytoplasm• Ribosomes• Mitochondria• Vacuoles (many/small)
Autotroph:• Cell Membrane• Nucleus• Cytoplasm• Ribosomes• Mitochondria• Cholorplast • Cell Wall• Large Vacuole
Types of Cells define:•Prokaryote•Eukaryote
Sketch out a plant and animal cell (p.221)
Both of these are examples of Eukaryotic Cells as they have membrane bound organelles

Why hard to tell??
Why onion not have chloroplast?
Underground…no SUN!

CELLS
Cell Membrane
• Allows things to come in and out of the cell
Cytoplasm
• Jelly-like substance that protects the cell
• Where the other objects live in the cell
Mitochondria• Changes food
into energy
• Powers the cell
Vacuole
• Stores minerals, nutrients, and water
Nucleus
• Controls the function of the cell
• Genetic Information (DNA)
• Oversees the making of the Product
Ribosome
• Make basic protein
Protein
• Success
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)
So, what is a cell??• List the organization of an
organism from largest to smallest.
• tissue• organism• cell• organ• gene• organelle• chromosome• organ system
OrganismOrgan SystemOrganTissuesCellsOrganelle (Nucleus)ChromosomesGene
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
Estrogen C18H24O2
Energy Transfer - Carbon and Oxygen Cycle Elements?
Compounds?
Molecules?
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
Squares
Hexagons
Circles
Reactants Products
Chemical Equation
How do things get in/out of cell?
Energy Transfer Picture
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
