Centrioles Flashcards
Where are centrioles located in animal cells?
In the cytoplasm near the nucleus, within the centrosome.
Do plant and fungi cells contain centrioles?
No, they do not contain centrioles.
What is the shape of centrioles?
They are barrel-shaped organelles.
How are centrioles arranged?
They consist of 9 groups of microtubule triplets arranged in a cylindrical shape.
How are centrioles positioned in relation to each other?
They are positioned at right angles to each other, functioning in pairs.
What microscope is needed to observe the detailed structure of centrioles?
An electron microscope.
What is one function of centrioles in cell division?
They organize microtubules that serve as the cell’s skeletal framework.
How do centrioles help with organelle positioning?
They help determine the positioning of the nucleus and other organelles within the cell.
What happens when a cell prepares to divide?
Centrioles move to opposite ends of the nucleus.
What role do centrioles play during mitosis?
They form regions from which the mitotic spindle originates and assist in chromosome condensation.
What is the function of the mitotic spindle?
The mitotic spindle attaches to chromosomes and pulls them to opposite ends of the cell, facilitating cytokinesis.
What is the function of centrioles in cytokinesis?
They are crucial for forming the mitotic spindle, which is necessary for cytokinesis.
Where are centrioles located when the cell is not dividing?
In the centrosome, near the nucleus.
