DO NOW

How are mitochondria and chloroplasts similar? How are they different?

Homework: Cell organelles worksheet due tomorrow

Quiz Friday. Money ($15) due TOMORROW!!!

Cytoskeleton

• Composed of Microtubules and Microfilaments

• Microtubules: Thick, strong spirals

• Microfilaments: long, thin, skinny protein

• Cytoskeleton provides structure

Microtubules

Cell division: Connect to chromosomes to help with cell’s first split

Locomotion in protists- cilia and flagella

Microfilaments

Cell movement

microfilaments are found attached to proteins on the cell membrane

Binding proteins allow microfilaments to push and pull on cell membrane to help the cell move

The Parts of The Eukaryotic Cell7) Support

CytoskeletonA network of thin, fibrous materials that act as a scaffold and support the organelles.

Microtubules – hollow filaments of protein.

Microfilaments – solid filaments of protein.

Locomotion

• Microtubules combine in specific arrangements to form cilia and flagella

• Cilia: little hairs outside a paramecium or other protists

• Flagella: long, thick tails

The Parts of The Eukaryotic Cell 8) LocomotionA) Cilia

Short, numerous, hair-like projections from the plasma membrane.

Move with a coordinated beating action.

The Parts of The Eukaryotic Cell8) Locomotion

B) FlagellaLonger, less numerous projections from the plasma membrane.

Move with a whip-like action.

Centrioles

Found near the nucleus (centrosome)

Function in the process of cell division (mitosis and meiosis)

During the time of cell division, there is a total of 4 centrioles

Meet a centriole

The Parts of The Eukaryotic Cell9) Cell Division

A)Centriolesmade of protein.play a role in the splitting of the cell

into two cells.found in animal and fungi cells.

Pick your favorite organelle!

Instagram it!

Describe the function of this organelle

How would the cell be affected if this organelle did not exist?

When you are done, stick it up on the board
