-
We, we just injected centrosomes into frog eggs which were either in interface so we could block the eggs in interface or in mitosis.
-
Higher plants and certain other organisms do not have centrosomes; they rely on microtubules and associated proteins to create a bipolar spindle.
Academic text (2009) -
Each centrosome in animal cells contains a pair of centrioles that assist in cell division.
-
The role of the centrosome is crucial for building the spindle apparatus in mitosis.
Synonyms

The term 'centrosome' is specialized and not directly inferable from its parts without specific biological knowledge.
Etymology
Centrosome comes from centro- meaning 'center' and the -some part from Greek soma meaning 'body', like the same root in chromosome. So a centrosome is a 'center body' in the cell that sits near the nucleus and helps organize the tiny tubes used in cell division.
