Bell-Ringer

1) What is the function of the organelle pictured below:

  • Transport materials and make mitochondria
  • Transport materials and make proteins
  • Transport materials and make energy
  • Transport materials and store water

2) The smooth ER can not make proteins because…

  • It does not have mitochondria
  • It is not located in the nucleus
  • It does not have ribosomes
  • It does not have vesicles

3) The Golgi Apparatus is most like a…

  • Power Plant – makes ATP for the cell
  • UPS Truck – transports materials
  • City Hall – the brain of the cell
  • Post Office – addresses proteins
golgi apparatus
Golgi Apparatus
  • The Golgi Apparatus is very similar to the ER in both function and appearance.
  • It is responsible for transporting proteins or lipids made by the ER to various parts of the cell.

Golgi Apparatus

golgi apparatus1
Golgi Apparatus
  • The Golgi acts like a Post Office.
golgi apparatus2
Golgi Apparatus
  • The Golgi acts like a Post Office.
  • It receives proteins, “addresses” them by attaching different carbohydrates, and then delivers them to the correct part of the cell.
golgi apparatus3
Golgi Apparatus
  • The Golgi acts like a Post Office.
  • The Golgi is very important in ensuring that proteins get delivered to the correct area of the cell.
play doh
Play-Doh
  • Create the Golgi Apparatus
  • Place it inside your cell.
vesicles
Vesicles
  • Vesicles are responsible for transporting substances throughout the cell (like the Post Office’s Trucks.)
  • They are spherical organelles, surrounded by their own membrane layer.
vesicles1
Vesicles
  • Vesicles are responsible for transporting substances throughout the cell (like the Post Office’s Trucks.)
  • They are spherical organelles, surrounded by their own membrane layer.

What are cell membranes made out of?

vesicles2
Vesicles
  • Vesicles are responsible for transporting substances throughout the cell (like the Post Office’s Trucks.)
  • They are spherical organelles, surrounded by their own membrane layer.

Phospholipids

vesicles3
Vesicles
  • Two important vesicles are:
    • Lysosomes
    • Peroxisomes
lysosomes
Lysosomes
  • Lysosomes are vesicles that form from the Gogli Apparatus.
  • Lysosomes are the cell’s “clean up crew.”
lysosomes1
Lysosomes
  • Lysosomes are vesicles that form from the Gogli Apparatus.
  • Lysosomes are the cell’s “clean up crew.”
  • These vesicles contain digestive enzymes that break down biological molecules and organelles.
lysosomes2
Lysosomes
  • Lysosomes in the liver break down carbohydrates in order to release sugar into the blood stream
  • White blood cells use lysosomes to break down invading bacteria cells.
lysosomes3
Lysosomes
  • Lysosomes are also responsible for breaking down cells when it is time for the cell to die.
  • This function is very important in maintaining the health of the organism.
peroxisomes
Peroxisomes
  • Peroxisomes are also vesicles that contain digestive enzymes.
  • These vesicles, however, are not produced by the Golgi Apparatus.
peroxisomes1
Peroxisomes
  • Peroxisomes are responsible for neutralizing compounds which would normally harm the body.
  • Peroxisomes are help detoxify alcohol and other drugs within the body.
play doh1
Play-Doh
  • Create some vesicles:
    • A Lysosome
    • A Peroxisome

(make them different colors)

  • Place them inside your cell.
cytoskeleton
Cytoskeleton
  • The cytoskeleton gives shape to the cell.
  • It is composed of a network of crisscrossing tubes and filaments in the cytoplasm.
cytoskeleton1
Cytoskeleton
  • The cytoskeleton is composed of three specific elements:
    • Microtubules
    • Microfilaments
    • Intermediate filaments
play doh2
Play-Doh
  • Create the cytoskeleton

(crisscrossing filaments in the cytoplasm)

  • Place them inside your cell.
cilia and flagella
Cilia and Flagella
  • Many cells have either cilia or flagella to help them move.
cilia and flagella1
Cilia and Flagella
  • Cilia – hair-like structures on the surface of the cell that assist in movement.
  • Cilia are short and present in great numbers.
cilia and flagella2
Cilia and Flagella
  • Flagella – tail-like structure on the surface of a cell that assists in movement.
  • Flagella are longer than cilia and are far less numerous when found on cells.
play doh3
Play-Doh
  • Create both cilia and flagella for your cell
  • Place them on the outside of your cell

1) Our bodies treat alcohol as a poison. Understanding this fact, we would expect someone who frequently abuses alcohol to have a higher number of __________ than someone who does not drink alcohol.

a) Lysosomes b) Mitochondria c) Peroxisomes

d) Ribosomes

slide33

Vesicles are most like what other organelle…a) The cell membrane – both are lipid bilayersb) The mitochondria – both make ATPc) The ribosomes – both make proteinsd) Cilia – both are involved in movement

3) Looking through a microscope at some cells, you notice that one is very fluid. It is unable to keep its shape. You determine that it has a problem with...a) its Golgi Apparatusb) its Ribosomesc) its Flagellumd) its Cytoskeleton

4) The sperm cells to the right are powered by...a) Flagellumb) Ciliac) DNA

d) Microtubule
