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.
Cilia and flagella
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
