cells of higher plants
Explanation
Solution
Centrosome is a complex structure consisting of two centrioles and centrosphere. It has a cylindrical structure without limiting membrane. It consists of nine triplet fibres, each consisting of three secondaiy fibres or tubules. These are enclosed in amorphous matrix. Centrosome separates into a pair of centrioles. The centrioles take part in formation of basal bodies and mitotic spindle. They are found in lower plants and most of the animals but these are absent from the cells of prokaryotes, diatoms, yeast and most of the higher plants.
