GUIDED QUESTIONS

What are cells?

What are the two main types of cells?

How do prokaryotic and eukaryotic cells differ?

Watch the video and then Think Pair Share in your group on what you learned from it.

WHAT DO THEY HAVE IN COMMON?

WHAT ARE CELLS? Cells are the basic unit of life.

What does that mean?• Everything that is living is made up

of cells.living

LIVING OR NON-LIVING?

RECAP Living = cells • Non-Living = no cells

HISTORY BEHING THE CELL

Robert Hooke, an English scientist, used a microscope to observe slices of cork.

He pointed out that the cork contained tiny rectangular chambers that he called cells. He believe that only plants had cells. His idea stood firm for 200 years.

In 1835, Mathhias Scleiden, a German scientist, used a microscope to study the parts of a plant. He concluded that all parts of a plant are made up of cells.

1836, Theodor Schwann, another German scientist, came to the conclusión that animals also are made up of cells.

THE DISCOVERY CONTINUES…

Meantime, a Scottish scientist named Robert Brown, had discovered an object near the center of the cells, which is now called the nucleus.

Rudolf Virchow, proposed that animal and plant cellls are produced only by the división of cells that already exist.

CELL THEORY1. All organisms are made up of

one or more cells

2. Cells are the basic unit of life in organizations

3. All cells come from other(pre-exixting) cells

CELLS BACKGROUND Cells come in different shapes Cells are different sizes There are many types of cells

Muscle Cells Nerve CellsRed

Blood Cells

THERE ARE 2 TYPES OF CELLS:

Prokaryote

Pro= beforeKaryote= nucleus

Eukaryote

Eu= trueKaryote= nucleus

Karyotic = nucleus

Cell Types

Prokaryotic

Eukaryotic

Both groups are prokaryotes (single-celled organisms without nuclei).

Single-celled organisms have all the characteristics of living things.

Scientists divide organisms into six kingdoms. All living things, including:

Plants Animals Protists Fungi Archaea Bacteria

RECAP

PROKARYOTIC VS EUKARYOTIC MINI- ASSESSMENT

The following slides will contain either prokaryotic or eukaryotic cells. Number your paper 1-10. When the cell is shown write whether it is a prokaryotic or an eukaryotic cell.

REMEMBER: Prokaryotic means the cell does not have a nucleus

•Eukaryotic means the cell does have a nucleus

DIFFERENCE BETWEEN EUKARYOTIC AND

PROKARYOTIC

Organisms that have prokaryotic cells are usually bacteria and viruses.

Organisms that have eukaryotic cells are animals and plants.

ORGANELLE

Parts of cell

ANIMAL CELL

CELL MEMBRANE

Protective outer covering of a cell

•Regulates what goes in and out of the cell

CYTOSKELETON

Provides structure to the cell

CYTOPLASM

Gel-like mixture in the cell

Contains cells’ organelles

RECAP

Prokaryotic Cell or Eukaryotic Cell

MITOCHONDRIA

Breaks down food and water and releases energy

GOLGI BODY Sorts, packaged, and ships cells’ materials

inside and outside the cell

RECAP

RIBOSOME

RECAP

ENDOPLASMIC RETICULUM

•Moves materials around in the cell

RECAP

LYSOSOME

•Digest old organelles

CENTRIOLES

Are used when cells replicate

RECAP

NUCLEUSThe brain of

cell

Contains DNA

Controls activities of the cell

RECAP

VACUOLEFluid-filled

cavity inside the cell

Contains digested food and waste materials that are on its way out of the cell
