Question
A non-membrane bound organelle found exclusively in
animal cells is _________.Solution
An organelle called a centrosome is found in the cytoplasm close to the nucleus. During mitosis, it divides, migrates to the opposing poles of the cell, and is involved in the development of the mitotic spindle, the assembly of microtubules, and the control of the cell cycle.
