Good Afternoon,

For your warm-up today, without consulting your notes, please draw a graphic that shows what you know about how

the following words are related in terms of organization:

Organ, Cell, Tissue, Organism, Organ System

Need a hint or a start?

Physical Science, and Chemistry Extension:

Where would you add the following words to your graphic?:

Organelle, Atom, Molecule

An organelle is a structure within a cell that performs a function. It is made of different molecules.

An atom is the smallest particle of an element.

A molecule is a collection of atoms held together by bonds.

Does this agree with how your added these words to your chart? If Yes - Congratulations! If not, re-work your chart.

The basic building blocks of life

Cells

All Cells~

have a cell membrane

contain heredity material in the form of DNA

have cytoplasm and organelles

are small

Cell Theory

All organisms are composed of one or more cells

The cell is the basic unit of life

All cells come from existing cells

What are the three statements included in cell theory?

1) All organisms are composed of ________________.

2) The cell is____________________________.

3) All cells come from _____________.

one or more cells

the basic unit of all living things

existing cells

Thank you Miranda

There are _____types of cells.two

Prokaryotes Eukaryotes

• No true nucleus• Few intracellular structures• Usually single• Circular DNA

• Membrane bound nucleus that houses the cell’s DNA• Membrane bound internal structures• Usually found in multicellular organisms• Linear DNA

Examples: BacteriaArchaea

Examples: ProtistsFungiPlants

Animals

Eukaryotes

Holding it all together: All cells have an outer covering that separates what is inside the cell with what is outside. All cells have a cell membrane, and some cells have an additional layer outside the cell called a cell wall.

Cell Membrane: All cells are covered with a cell membrane.It keeps the cytoplasm in, and allows nutrients in, wastes out, and interaction with other cells.

Cell Wall: Plants and algae have a cell wall made of cellulose. The cell wall provides strength and support.

Organelles and what they do.

NucleusThe nucleus contains the cell’s DNA and is the “control center” of the cell

Eukaryotes

Organelles are structures in the cell that enable the cell to live, grow, and reproduce

Organelles

For Example:

Read pages 68 - 74 in your textbook. Make a chart of the organelles and their specific functions.

On a white piece of paper from the back of the room please draw the following cells:

One example of a Prokaryote

One example of a Eukaryotic cell from a plant

One example of a Eukaryotic cell from an animal

Maybe you will divide your paper like this.

ArchaeaScientific NamePyrodictium

Scientific NamePyrolobus

CommentsPyrolobus, the organism with the highest known growth temperature (113°C).

Most archaea live in Earth’s most extreme environments, like salty lakes, boiling hot springs, deep ocean thermal vents, and environments that completely lack oxygen. They are the radically extreme life forms of the planet, and are sometimes called Extremophiles (lovers of extreme environments.)

Archaea live inside cow’s stomachs, and are the reason cows burp and errr.... expel Methane gas. We can use these organisms to convert garbage and poop into methane - which is a valuable fuel.

Archaea have characteristics in common with both Bacteria and Eukaryotes.

Cell membrane

DNA

Cytoplasm

organelles

are small
