Are spindle fibers found in plant cells?

Spindle fibres compose a protein structure segregating the genetic material in a cell. Plant cells lack centrioles but still, they are capable to form a mitotic spindle from the centrosome area of the cell located just exterior to the nuclear envelope. …

How are spindle fibers formed in plants?

As spindle fibres are formed by centrioles during mitosis. But they are absent in plant cells. So who forms spindle fibres in plants in order to carry out mitosis.

How do plants work without centrioles?

plant cells without centriole build special vesicles from their Golgi apparatus which are important for cell division. In some cases the cells walls themselves organize many microtubules that form the spindle during mitosis.

Why do plants not need centrioles?

Centrioles are absent from the cells of higher plants. In higher plants mitosis takes place perfectly satisfactorily with microtubules forming spindle fibres but without the help of centrioles. The function of centrioles therefore remains something of a mystery.

How plants and other organisms work without centrioles?

Explanation: plant cells without centriole build special vesicles from their Golgi apparatus which are important for cell division. In some cases the cells walls themselves organize many microtubules that form the spindle during mitosis. Vesicles ride on microtubules to get where the are going inside the cell.

Why plants do not have centrioles?

What happens if centrioles are missing?

Scientists have found out that the cells with their centrioles removed show a delay in spindle assembly and a higher rate of instability in chromosomes. It results in a defective or asymmetric mitosis and also triggers apoptosis.

Can we survive without centrioles?

For most of the organisms that bear these protrusions, centrioles are an absolute necessity as they are responsible for developing the hair-like projections. Without cilia and flagella, the motion and food detection of these organisms would get suspended as a result of which survival would look pretty bleak.
