CHAPTER 6: CELL STRUCTURE & FUNCTION

SOME RANDOM CELL FACTS

•The average human being is composed of around 100 Trillion individual cells!!!•It would take as many as 50 cells to cover the area of a dot on the letter “i”

WOW!!!

I.CELL THEORY

A. 1665- Robert Hooke- used microscope to see cork cells- named them “cells”

*Hooke named them this because he believed they looked like the little rooms monks lived in at monasteries which were called cells.

B. 1673 Anton van Leeuwenhoek- Used a handmade microscope to observe pond scum & discovered single-celled organisms• He called them “animalcules”• He was the first to make a simple light microscope.

Development of Cell Theory

D. 1838- Matthias Schleiden (German Botanist)-Concluded that all plant parts are made of cells

E. 1839- Theodor Schwann (German physiologist) -Stated that all animal tissues are composed of cells.

F. 1858- Rudolf Virchow (German physician) -Concluded that cells must arise from pre-existing

cells.

3 Parts of the cell theory:

A.All living things are composed of cells

B. Cells are the basic units of structure and function

C.New cells are produced from existing cells

Cell Theory Song!http://www.youtube.com/watch?v=KuJqqiATlqw

HOW HAS THE CELL THEORY BEEN USED?

•The basic discovered truths about cells, listed in the Cell Theory, are the basis for things such as:●Disease/Health/Medical Research and Cures(AIDS, Cancer, Vaccines, Cloning, Stem Cell Research, etc.)

Review Compare and Contrast Types of Cells!

Quiz tomorrow: Cell Theory, Compare and Contrast Types of Cells!

WHAT ARE THE DIFFERENCES?

Eukaryotic Cell

Cells are divided into two categories:

1. Prokaryotes

a. much smaller and simpler, no organelles

b. no membrane bound nuclei

c. contain cell membrane, DNA, cytoplasm

ex: bacteria

2. Eukaryotes- more complex!a. contain many organelles, larger, true nucleus

1.) organelle- specialized structure that has a specific function (in cell)

b. All plants, animals, and fungi are eukaryotes*all our cells are Eukaryotic!

1. LABEL EACH SIDE OF THE VENN DIAGRAMA B

- Cell membrane

- Contain DNA

- Cytoplasm

- Large & Complex

- Contain Nucleus

- Membrane-bound organelles

- Make up plants, animals, fungi, and protists

- Small & simple

- No nucleus

- No organelles

- Bacteria

2. What type of cell is this?

3. Name one reason you know it is this type of cell

4. This cell has whip-like flagellum, what do you think those might be used for?

5. Do you think it would be more likely to assume this is a bacteria or plant cell? Why?

6. What type of cell is this? (prokaryotic/eukaryotic?)

7.Name one thing about this cell that helped you know it was that type of cell:

8. Do you think this is more likely a plant cell or an e-coli cell?

Cell membrane

SIMILARITIES:

• All eukaryotic cells have a cell membrane, nucleus, and cytoplasm.

Animal Cells have Centrioles!(which plant cells do not!)

Both Plant and Animal cells have vacuoles, however, Plant cells have VERY LARGE vacuoles, while animal cells have many small vacuoles.

ØPlant cells contain many of the same organelles you would find in an animal cell with the exception of a few key players

Ø(1)Cell Walls and (2)Chloroplasts are found in plant cells and not animal cells.

What are the 3 parts to the cell theory??

Objective for today:

Compare and Contrast Prokaryotic cells to Eukaryotic cells

2 main types of microscope:

1. Electron microscopes:

a. forms an image of a specimen using

a beam of electrons rather than light

b. Specimen placed in a vacuum so no living samples are used

Microscopes

2. Light microscopes-

a. uses two lenses

b. light from the base shines up through the specimen

c. Ocular lens is 10x, objective lens is either 10x, or 40x

Ex: What is the magnification of an object which uses the 40x objective lens?

Ocular 10x * Objective 40x= 400x

What is diffusion?

Give an Example.

Does Diffusion use energy?

What is a solute? Give an example!

--Let’s go over yesterday’s Diffusion Reinforcement!!!

Movement of Water:

Osmosis- no energy used

1. Diffusion of water through a selectively permeable barrier (like a cell membrane)

A. Selectively permeable –not all things go through

2. Water moves in direction of where there are more solutes

Ex:

Isotonic solution- cell and solution both have the same concentration of water and solutes

Ex: blood cells in plasma

Hypertonic solution- Solution surrounding the cell has more solutes than the cell

a. Water moves out of the cell-cell shrivels

Hypotonic solution- cell has more solutes than the solution around it

a. Water moves into the cell

-cell could burst

-plant cell wall prevents that

Blood cell/ body cells in animals not usually surrounded by pure water!

If you were absent Weds...check the box… and you owe me a quiz!!!!

Bellringer:

On a ½ sheet of paper,

Describe the process of diffusion. Does diffusion use energy?

Think about the structure of the cell membrane, what structures sit in the membrane to help move large particles across?

E. Facilitated Diffusion

1. Carrier protein- used in facilitated diffusion-transport protein that carries something across the cell membrane

Which direction are the molecules moving?

Do you think this will require energy?

F. Active Transport- movement of a substance from an area of low conc. to an area of high conc.

(the opposite of the normal way)

1. Energy is used in the form of ATP

2.Membrane pumps- proteins move substances from an area of low to high conc.

ex: Sodium-Potassium pump

Active Transport Video

Don’t require energy

G. Vesicles can be used to transfer items across the cell membrane

1. Endocytosis- move substance inside cell--needs energy!

2. Exocytosis- moving a substance out of the cell--needs energy!a.) fuse with membrane, releasing contents ex: proteins leave the cell in this way

5. Draw a picture of a section of the cell membrane

An adventure into the cell!

Nucleus- controls cell and contains DNA

nucleolus- starts assembly of ribosomes

Nuclear membrane (envelope)- surrounds nucleus, lots of pores for items to move in and out

A.Nucleolus makes ribosomes which then leave the nucleus and attach to E.R.

Ribosome- place of protein production (may be free or attached)

Endoplasmic Reticulum- parts of cell membrane are made and proteins are modified

Rough E.R.- covered in ribosomes

a. Proteins are made on the ribosomes (on the ER) and travel directly into the e.r.

Smooth E.R.- make lipids (fats)

C. Golgi Apparatus- package and sort proteins

1. Proteins go from the R.E.R. to the G.A. and are then sent to their final destination

D. Vesicles- small sac that transports items around the cell

E. Lysosomes- small sacs filled with enzymes which breakdown food particles or old organelles

F. Centrioles are organelles found only in animal cells that help with cell division.

G. Mitochondria- “powerhouse” of the cell

1. Converts food molecules to energy (glucose to ATP)

IV. Plant cell organelles

A. Vacuoles- saclike structures that hold water, a full vacuole allows for plant cells to stay rigid

EXAMPLE OF SCIENCE PARAGRAPHThe outside of an animal cell is covered in a cell membrane,which allows substances to pass in and out. Inside of the cell from the cell membrane to the nuclear envelope is cytoplasm. Cytoplasm contains enzymes because it is the location where many chemical reactions take place. The nuclear envelope serves as the outer boundary of the nucleus and has many pores that allow materials inside and out. Inside the nucleus is the nucleolus which makes ribosomes. These ribosomes leave the nucleus through the pores in the nuclear envelope.
