Why higher plants lack centrioles?

Question

Why do plant cells not have centrioles?

Answer 1

In higher plants mitosis can take place with microtubules forming spindle fibers without the help of centrioles.

Answer 2

From the Internet:

Plant cells without centrioles build special vesicles from their Golgi apparatus which are important for cell division. ... Animal cells are much evolved than plant cells that's why they have centrioles . Spindle formation is very much different in plant cells than in animal cells due to the absence of centrioles
