Cilia and Flagella_3rd

Composed of microtubules in a "9 + 2" sequence

( 9 + 2 sequence)

 

  • Form a particular strict pattern

 

  • They range in different sizes and amounts

    • Cilium?

    • Cilia?
  •  They fringe the edges and sides of Eukaryotic cells

  • They range in different sizes and amounts 

  • Cilia moves back and forth across the top of the surface

 

 

***Like the brissels of a broom it sweeps

 

  •  "This waving motion moves fluids, such as mucus, over the surface of certain tissues, including those that form the inner linings of the respiratory tubes (McGraw-Hill)."

  • There are two types of Cilia

    • Motile Cilia

      •  Beats in a single direction

    • Primary Cilia

      •  Are used as sensory organelles

  •  Cilia and flagella make up the organelles known as undelipodia

  • "An undulipodium or 9+2 organelle is an extacellular projection of a eukaryotic cell containing a microtuble array (Undulipodium)"

  • Cilia most likely is found in cycads

  • Is not often found in plants

  • Ciliates have motile cilia which they use to move fluids over their surface

 

 

FLAGELLA...

 

Three types of Flagella:

1. Bacterial

  •  Made up of protein flagella

  •  It is a thick hollow tube

  •  It moves by a protein found at the base of the flagellums cell membrane

  •  Flagella move by rotating, the "engine" in them is proton motive force by the flow of protons (hydrogen ions) at full force this flow can reach up to 6,000 to 17,000 rpms but it usually on reaches 200 to 1,000 rpms 

  • "They move at a constant speed but can decrease and increase their rotational speed in relation to the strength of the proton motive force ()."

  •  Can self assemble without any other organisms help

 

2. Archael

  • Similiar to Bacterial Flagella
  • Has extended filaments and they rotate to thrust the cell forward

 

3. Eukaryotic

  • Completely different from prokaryote

 

Only shared characteristic of all of these is:

     *Outward Appearance*

 

 

Differences:

 

  • Cillia:    

  1. Tail moves back and forth

  2. Transports things through liquids

  • Flagella:

  1. Tail propels

Moves single cells

 

 

 

 

FAQs

 

What does the flagellum do?

Flagellum moves important specific information across the cell.  An example of this is a stomach ulcer causes by bacteria called Helicobacter pylori. To heal the ulcer the immune system moves many different flagella through the mucus lining into the stomach. 

 

How do cilia and flagella tie in with each other?

 They both use there tails and both transport material. 

 

What are the differences between the cilia and the flagella?

Cilium’s tail moves back and forth. Flagellum propels.

 

Do cilia or flagella move anything across the cell?

Cilia moves things through liquids across the cell, and flagella transports single cells.

 

 What are cycads?

Cycads are just an example of where cilia is located. Cycads are a group of seed plants.

Where is yo pictures?

Our pictures are all over the page.

Where are cilia and flagella found?

Cilia is found in eukaryotic cells. Flagella is found in prokaryotic cells and eukaryotic cells.

 Where is this found on the cell?

Cilia and flagella are not found on the cells. They are a process that occur out from our cells.

What are the differences between the cilia and the flagella?

Cilia moves its tail back and forth. Cilia transports things through liquids. Flagella tails propels. Flagella projects its self through the fallopian tubes.

 What is a "9+2" sequence?

The “9+2” sequence is also known as undulipodium. It is the projection of a eukaryotic cell through microtubules.

How are the flagella and cilia alike?

They are similar in their structures. They are both undulipodia.

Why do cilia form a strict pattern?

They must maintain a strict pattern because they must be able to start, maintain, and finish out their jobs correctly.

 Does cilia or flagella move anything across the cell?

Flagella is able to swim across the cell surface and cilia moves liquid over the cell surface.

Why are there only three types of flagella?

There are only three types of flagella because there are three different structures and functions of flagella.

Can you have flagella and cilia on the same cell?

No because cilia is located in the respiratory tract and flagella is located on sperm cells.

 How are cilia and flagella important in the cell?

Cilia usually move the substances along like mucus. Flagella move the entire cell like, a  propel.
