Which of the folliwng structure will not be common to mitotic cell of a higher plant

Options

B. Centriole
C. Centromere
D. Spindle fibres

Answer

B

Explanation

Centrosome is found in animals, Euglena, Nitella, some fungi and members of dinoflagellate. It is found near the nucleus.
Centriole is not common to mitotic cell of higher plants. Main function of centrosome is at time of cell division when the two centrioles separate and move on two poles. Aster and spindle are formed from it which help in the movement of chromatids. They form basal body, cilia, flagella , etc.
Centriole is rich in tubulin and ATPase.
Centrioles replicate in ` G_(2)` - phase of interphase of cell cycle but do not initiate cell division.
