INTERESTING FACTS ABOUT YOUR Body -Scientists say the higher your I.Q. The more you dream. -The largest cell in the human body is the female egg and the smallest is the male sperm. -You use 200 muscles to take one step. -The average woman is 5 inches shorter than the average man. -Your big toes have two bones each while the rest have three. -A pair of human feet contains 250,000 sweat glands.
-A full bladder is roughly the size of a soft ball. -The acid in your stomach is strong enough to dissolve razor blades. -The human brain cell can hold 5 times as much information as the Encyc. Britannica. -It takes the food seven seconds to get from your mouth to your stomach. -The average human dream lasts 2-3 seconds. -At the moment of conception, you spent about half an hour as a single cell. -There are about one trillion bacteria on each of your feet.
-Your body gives off enough heat in 30 minutes to bring half a gallon of water to a boil. -The enamel in your teeth is the hardest substance in your body. -Your teeth start growing 6 months before you are born -When you are looking at someone you love, your pupils dilate, and they do the same when you are looking at someone you hate. -Your thumb is the same length of your nose. https://youtu.be/gFuEo2ccTPA?list=PLhWQfyIjGDq40wpDLJBsLcNcykz8h7FZf
CHAPTER 3 CELL STRUCTURE You are a metropolis of 50 trillion citizens. Each of the cells in your body can be considered a sentient being in its own right. They all act together as a community, performing an ongoing act of prodigious collaboration.
Dr. Bruce Lipton Biologist Section Outline Section 7-1 CHAPTER 3: CELL STRUCTURE
Section 1. Looking at Cells Section 2. Cell Features Section 3. Cell Organelles Go to Section:
PERIMICIUM TIGER LILLY LOVE POLLEN Largest cell= 8 cm Average cell= 0.002 cm Unaided eye can see = 0.01 cm
STREPTOCOCCUS CELL = THE BASIC UNIT OF LIFE
Anton Von LEEUWENHOEK Early 1600s Discovered living cells Simple Microscope Blood cells and
Bacteria from teeth ROBERT HOOKE 1665 Termed the word Cell -Hollow boxes
-Monks Cells CORK CELLS Two Lenses (Compound) Light Source (Light)
COMPOUND LIGHT MICROSCOPE -Series of lenses -Light passes through the object
COMPOUND LIGHT MICROSCOPE Technology Cell Part: 400x 0.00002 cm
ELECTRON MICROSCOPE 1940s 1 million x CELL THEORY
1. ALL ORGANISMS ARE COMPOSED OF ONE OR MORE CELLS. THE CELL IS THE BASIC UNIT OF ORGANIZATION OF ORGANISMS. 3. ALL CELLS COME FROM PREEXISTING CELLS
WO BASIC CELL TYPES PROKARYOTIC EUKARYOTIC Prokaryote Common:
1. Cell Membrane 2. DNA Eukaryote PROKARYOTIC CELLS No True Nucleus
Bacteria Organism is a single cell (unicellular)
= a cell that lacks internal structures surrounded by membranes Cyanobacteria E. COLI
Cocci LYME (TICK) EUKARYOTIC CELLS True Nucleus
= cells containing internal, membrane bound structures Some are made of single cells Most are made
of multiple cells (multicellular) Advantages? Muscle Cells Skin Cells
Specialized Blood Cells Brain Cells
EUKARYOTIC CELL STRUCTURE Organelles = internal membrane bound structures within a cell Plant Cell
Cytoskeleton Cilia and Flagella CHAPTER 3 QUIZ #1 1. What does the Cell Theory state? 2. Compare and contrast Prokaryotic and Eukaryotic cells.
3. Five scientists made major contributions to the Cell Theory. In chronological order, list their names and their contributions. 4. Define the word organelle and list 3 organelles inside a cell. What type of microscope do you use in lab? List 2 other types of microscopes and describe how they function.
