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 AutotrophHeterotroph Eukaryotic Cell Organelles and Functions 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?

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 Organism Organ System Organ Tissues Cells Organelle (Nucleus) Chromosomes Gene
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 C 19 H 28 O 2 Serotonin C 10 H N 2 Adrenaline C 8 H 11 O 3 N Glucose: C 6 H 12 O 6 Cholesterol C 27 H 45 OH Estrogen C 18 H 24 O 2
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!!

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? 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
