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
