I need some things about my project on centrioles.
I need these questions answered.
  • What job or service does your organelle provide for the cell?
  • What organelles does your organelle work with in order to help the cell perform its functions?
  • What cell processes is your organelle part of? (Example: Cell Reproduction, cell transport, photosynthesis, cellular respirtaion, etc.)
  • Create an analogy that explains the overall purpose of your organelle.
  • Describe the structural design of your organelle. (Example: Membranes, compounds, shape, pigments, etc.)
  • How does the design of your organelle help it perform its job?
  • Is your organelle located in a plant cell, animal cell, or is it found in both?
  • Is your organelle found in the nucleus, cytoplasm, or outside the cell?

Your help is very much appreciated.

Thank You,

Tyler Hendrix

- Centrioles are involved in the organization of the mitotic spindle and in the completion of cytokinesis.

- Microtubules (proteinious components of the cytoskeleton). Arguably, also the nucleus.

- Mitosis, Meiosis (Basically cell division/reproduction)

- A Centriole is like a straw because they both are tubes that let things get from one end to the other end.
The centriole has a round look to it because it is made from nine triplets of microtubules that make a straw-like (as said above) look.
...or...
A centriole is like a clothing rack because centrioles organize cell division and clothing racks organize sizes of clothing
...or...
centrioles are like the North and South poles.
...or...
Centrioles are like cables found in the cell that are used in things from motor function to division of DNA.

- The are not membrane bound, but are like long, straight spindles.

- centrioles spin rapidly around the chromosome replications and create spindle fibers which join the two centrioles. Then the membrane pinches inward and the chromosomes are pulled by the spindle fibers towards the centrioles. they need to be fibrous in order to have this effect.

- not found in plant cells

- outside the nucleur envelope.

Animal cells contain 2 centrioles, which together form the structure, centrosome. In other words, the centrioles are found within the centrosomes, which is a small region in the cytoplasm near the nucleus. Similarly, some sources say that centrioles are also found as single structures in cilia and flagella.

They are only found in animal cells; plant and fungi LACK centrioles.
