Centrioles

Question 1

Centrioles - function

Answer 1

• create spindle during cell division
  - which separate chromosomes
• creates microtubules
  - give cell shape and support

although plant cells do not have centrioles they can still produce spindle and microtubules

Question 2

Centrioles - structure

Answer 2

• situated in the centrasom
  - part of the cytoplasm
  - outside the nucleus
• contains two empty cylinders at a right angle to
  each other
• each cylinder includes nine set of microtubules
  which are set in a circle
• during cell division centrioles duplicate
  themselves
  - each new cell has a pair of centrioles
