Why centrioles are present in animals but not in plants?

Answer 1

Centrioles are responsible for the formation of the spindle which is made of microtubules. These structures constrict around the outside of the cell causing the cell to cleave in two. Plant cells have a rigid cell wall that could not be cleaved by these organelles. The cell wall grows in between the two new daughter cells, separating them from each other. This is why plant cells do not need centrioles, as they would not help the cell to divide anyway.

Answer 2

Centrioles are present in animals because they are needed for cell division, particularly in forming the spindle fibers that separate chromosomes during mitosis. Plants, on the other hand, have different structures called microtubule organizing centers that fulfill a similar function, so they do not require centrioles.

Answer 3

the plant cells do not contain centrioles because the cell division of the plant cell isn't like the animal cells . the centrioles help those chromosomes to move apart and divides one cell to two new cell in the animal cell . this process called Mitosis . in plant cells , the chromosomes can move apart itself and can produce new two cells unless those plant cells do not have any centrioles.

Answer 4

I do not think we know why they are in animal cells yet! Excising them with a laser seems to do nothing in interrupting replicative processes. The centrosomes still spin the mitotic/meiotic spindle without them!

A question you can answer when you become a biologist. I think my info could be slightly out of date. You decide.

Answer 5

They simply don't, and nobody can give any reason why so far as popular science knows.

Answer 6

Lysosome, Centrioles (2), and Microtubules.

Answer 7

its preset in the centrosome retard
