5 Questions
What is the typical arrangement of centrioles in a cell?
In pairs, usually located at right angles to each other near the nuclear membrane
What is the function of centrosomes in cells?
To organize and reorganize microtubules
What is the composition of a centriole?
Nine triplets of microtubules
What is a characteristic of centrosomes in plants and fungi?
They lack centrioles but still contain microtubule-organizing centres
What is the region around the centrioles called?
Centrosome
Study Notes
Centrioles
- Found in animal and most protist cells, occurring in pairs near the nuclear membrane
- Each centriole consists of nine triplets of microtubules
Centrosome
- Region surrounding the centrioles
- Acts as a microtubule-organizing center, nucleating microtubule assembly
- Responsible for reorganizing microtubules during cell division
- Found in plants and fungi, but lacking centrioles, still containing microtubule-organizing centers
Learn about centrioles, barrel-shaped organelles found in animal and protist cells, and their role in microtubule organization and cell division. Discover the structure and function of centrosomes and their importance in cellular processes.
