Unformatted text preview: Centrioles By Ambrocia Ramirez Biology 1406 Professor Mello 1 Who am I? 2 ● Organelle Name: Centrioles ● Location in the cell: In animal cells centrioles are located in, and form part of, the centrosome where they are paired structures lying at right angles to one another. In this context they are possibly involved in spindle assembly during mitosis. The centrosome is positioned in the cytoplasm outside the nucleus but often near to it. ● What type of cell(s) is it found in?: Found only in animal cells and some lower plants 3 ● Who discovered the organelle?When was it discovered?: It was first discovered by Theodor Boveri and Edouard Van Beneden in the 1880s, the centriole remains a surprisingly mysterious organelle. 4 Function of the Organelle 5 What is the primary purpose in the cell?: 1. Cell division: The main function of the centriole is to help with cell division in animal cells. The centrioles help in the formation of the spindle fibers that separate the chromosomes during cell division (mitosis). Does it have any other purposes?: 2. Cellular Organization: Centrioles are a very important part of centrosomes, which are involved in organizing microtubules in the cytoplasm. The position of the centriole determines the position of the nucleus and plays a crucial role in the spatial arrangement of cell organelles 6 ● Does it create any products?: In animal cells centrioles organise the pericentriolar material to produce microtubules including mitotic spindle fibres. 7 3D Model Photo 8 9 Why should this organelle win the beauty pageant, aka why is it the important organelle in the cell? 10 ● What would happen to the cell if this organelle was missing?: Without centrioles, the cells' organelles would not stay in their proper places, and microtubules would not be able to function properly, which would leave cells unsupported and liable to lose their shape. And the chromosomes would not be able to move. ● Why is this organelle the most important organelle in the cell?: Centrioles are important organelles inside cells. They are part of cell division, cilia and flagella. However, when problems occur, they can lead to several diseases. For instance, when a mutation in a gene causes protein malfunctions that affect cilia, it can lead to serious genetic disorders that are fatal. 11 MLA Work Cited ● ● ● ● ● ● “Centriole - The Almighty Cell.” Google Sites, sites.google.com/a/asu.edu/the-almighty-cell/the-source/animal-cell/centriole. “Centriole.” British Society for Cell Biology, bscb.org/learning-resources/softcell-e-learning/centriole/#:~:text=.
