Warm-Up 10/6/11

Teach the Teacher: What is the best school lunch menu item?

Review: Tell me as much as you can remember about the plasma membrane.

Learning Target: Eukaryotic cells have what kind of things in it?

CELL ORGANELLES Red 1 version

Cilia

• Projection from cell walls that aid motion and also sweep substances along surfaces.

• Found in some Animal cells, Protist cells, and Prokaryotic cells.

Flagella Found in some

animal cells, prokaryotes, and some plant cells

flagella is a hollow tube 20 nanometers thick

LYSOSOMES

Lysosome Stuff

A vesicle that contains digestive enzymes for the breakdown of excess or worn-out cellular substances.

Nucleus PowerPoint

Phy. ScienceBy: Ed Knife

Nucleus

• Is in the center of the cell.• A membrane enclosed organelle

found only in Eukaryotic Cells.• The main structure of the nucleus is

the Nucleus Envelope.

The Nucleus’s Job

• Contains most of the cell’s genetic material.

• It also holds all of the cell’s DNA.• Regulates all cell activity.• Brain of the cell.

The mitochondrion•The Mitochondria provide the cell with the energy needed to move, and divide•It is the part of the cell that is needed for energy and they do differ in size and shape only depending on the cell type.•Mitochondria are membrane bound and such as the nucleus they have a DOUBLE membrane.

• Outer Membrane- smooth▪ -Inner Membrane- rough, convoluted forming folds called Cristae.

▪ -Cristae increases the inner membranes surface area, on the Cristae sugar is combined with Oxygen to produce the energy source for the Cells (ATP)

▪ -ATP: Adenosine 3 Phosphate, the energy is stored in here, once used it becomes (ADP) Adenosine 2 Phosphate.

In All Eukaryotic Cells. Produces the energy available to the

rest of the cell(pg 199)

Cytoskeleton

A framework for the cell within the cytoplasm

Consists of a matrix in which the cells organelles are suspended

Ribosomes

• A Ribosome is an organelle whose function is to assemble the 20 specific amino acid molecules to form the particular protein molecule.

• A ribosome is just a simple cell organelle that helps manufacture proteins. We need these inside our cells in order to survive.

ENDOPLASMIC RETICULUM

By Ray Marks

Endoplasmic Reticulum

Endoplasmic reticulum is a network of tubules, vesicles and sacs that are interconnected. They may serve specialized functions in the cell including protein synthesis, sequestration of calcium, production of steroids, storage and production of glycogen, and insertion of membrane proteins.

Interesting fact

Endoplasmic reticulum manufactures substances in the cell. It is a set of flattened membrane sheets.

Rough ER has ribosomes attached to it. it manufactures proteins.

Smooth ER Contains enzymes that manufacture fats, phospholipids and steroids

Golgi Apparatus

A flattened stack of tubular membranes that modifies proteins and packages them for distributions outside the cell. The golgi body recieves

Substances from the endoplasmic reticulum

-all Eukaryotic cells.
