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.
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.
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.
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 I think my info could be slightly out of date.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.
They simply don't, and nobody can give any reason why so far as popular science knows.

Is centrioles in plant cells?
NO plants do not have centrioles, but have a spindle closely identical to the Animals
Which type of amino acid is present in animals but not in plants?
carnitine is present in animals only
Do angiosperms have centrioles?
No, angiosperms do not have centrioles. Centrioles are found in animal cells and some lower plant groups such as algae, but they are absent in most higher plants, including angiosperms.
Do human cells have centrioles?
No they do not. Animal cells have centrosomes, which are defined as a pair of cetrioles. Plants do not have centrioles, so they cannot have centrosomes. Plants have microtubule organizing centers (MTOCs). Centrosomes (in animals) and MTOCs (in plants) are where microtubules of the spindle originate during mitosis
What structures are present in animal cell but not in plant cell?
Chloroplasts, Cell wall, and Plants have really large Vacuoles compared to Animals.
What organelles are not in plant cells?
chloroplasts are present in plants but not in animals centrioles are present in animals but not in plants
What cellular structure are present during mitosis in animals but not in plants?
centrioles
Which organelle is present in plants but not in animals?
Chloroplasts are only found in plant cells.
Is centrioles in plant cells?
NO plants do not have centrioles, but have a spindle closely identical to the Animals
What structures are found in animals only and plants only?
centrioles
Plants and centrioles?
Plants do not have centrioles.
Do plant's cells have centrioles?
No, plant cells do not have centrioles. Centrioles are only found in animal cells and are involved in organizing the microtubules during cell division. Plant cells use a different mechanism to organize their cytoskeleton during cell division.
What structures are found in animals cell but not in plants cell?
Animal cells have centrioles.
What is the different of plants and animals?
1) Plant cells have cell wall which is absent in animal cell. 2) Plant cell lack centrioles whereas animal cells have centrioles.
Which type of amino acid is present in animals but not in plants?
carnitine is present in animals only
Do angiosperms have centrioles?
No, angiosperms do not have centrioles. Centrioles are found in animal cells and some lower plant groups such as algae, but they are absent in most higher plants, including angiosperms.
What kingdom are plant cells?
Plants belong to the kingdom Plantae. Animals belong to the kingdom Animalia. Plant cells do not have lysosomes and centrioles.
