Transcript of Cells & Organelles

Each cell has a
specific job
, something that it is good at, better than all the other cells in our bodies. Whatever a cell
does
is called it's
function
.
Structure
In order to do their job, cells must have a

specific shape
. How a cell
looks

and what it is made of is called its

structure
.
Cell Theory
1. All organisms are made of cells
Function
Nucleus
Control center

Works like the "
brain
" of the cell
Ribosome
Makes proteins

Works like a "
contractor
", building more cell parts.
Endoplasmic Reticulum [e.r.]
Protection
Cell Wall
Golgi Apparatus
Acts like a "
post office
."
Intro to Cells
Organelles
Organelles
Cells and Organelles
Cells are the most basic unit of life
Just like our bodies are made up of trillions of tiny cells, our cells are made up of hundreds of tiny cell "parts", called
organelles
.
Operates like an information "
highway
"

Sends
messages
from the nucleus to different parts of the cell
Organelles make up the
inner structure
of the cell
Cell Membrane
Protects
plant
cells like the "
wall of a house
."
Helps plants stand upright.
Makes tree bark rough and rigid.
Protect
animal
cells like a "
fence
".
Allows small particles to pass through.
Cell Membrane
Small Organelles
Vesicles
Lysosomes
Centrioles
Mitochondria
Chloroplasts
2. All new cells are made from old cells.
3. The cell is the most basic unit of life.
Small packages that transport molecules throughout the cell
Works like "
packages
" at the post office
Cytoskeleton
Provides
structure
and support.
Vesicle Formation
vesicle
Break down molecules and "dead" organelles
Works like a "
garbage disposal
"
Small cylinders that build microtubules during mitosis.
Work like a "
building's foundation
" that holds up support beams
Centrioles
Microtubules
are long hollow tubes that act as "train tracks" for the movement of molecules and organelles such as vesicles.
This means that if it's smaller than a cell, it's
not alive!

This is your first "flipped" assignment. Work your way through the prezi taking notes as you go. Your notes will be collected for a homework grade.
Review your three learning targets.

To the left of each target, write a number 1-10 to represent your understanding of each
I can
statement.
Self-Assessment
Provide energy to perform cell functions - like a "
generator
."
Power house of the cell
Make food for
plant cells
Uses the sun's energy to make sugars like an "
oven
."
Mitochondria
Chloroplast
Transports molecules throughout the cell in vesicles
This is an example of an animal cell
This is an example of a plant cell
Central Vacuole
Only found in
plant
cells
Stores food and water for the plant, like a "
refrigerator
."
Here's another look at plant and animal cells. What do you recognize? Which organelles do they have in common? Which organelles are different?
Animal
Plant

White blood cells, called leukocytes (loo-ko-sites) protect the body from bacteria and viruses. When a person has leukemia (loo-key-me-ah), they don't have enough white blood cells, causing them to become very ill.
A sperm cell has a tail so that it can swim far (and fast). Think of a salmon swimming upstream - this is the job (or function) of the sperm cell.
Let's take a tour of the inside of a cell. Pay close attention, what do you recognize? Can you describe the function of each organelle?
Cytoplasm
Jell-o like substance that holds all the organelles in place
Think of the "
floor
" in your house holding all the furniture in place
Learning Targets - I Can...
Display an understanding of the three principles of the Cell Theory
Draw and label the structure of organelles
Identify the differences between plant and animal cell anatomy
At the top of your notes, write out the three learning targets.
Leave space to the left of each for later.
10 - Got it! I could teach the class!!
5 - I should probably look back through the presentation once more.
1 - Organelles? Is that from Elder Scrolls?
I can display an understanding of the three principles of the Cell Theory
I can draw and label the structure of organelles
I can identify the differences between plant and animal cells
Levels of Cellular Organization
Use this key as a guide:
