Karyokinesis is not followed by cytokinesis

Multinucleate condition arises

Absence of telophase

Nuclear cytokinesis is not followed

11 / 25

Mitotic divisions in .............. result in continuous growth in the plants

lateral meristematic tissue

All of these

15 / 25

How does the metaphase differ from anaphase ?

Chromatids having centromere

Condensation of spindle fibres and the centromere splits and will separate

All of the above

For chromatin

16 / 25

pectin

20 / 25

Structures serve as the site of attachment of spindle fibers to the centromere of the chromosomes.

Centromere

Metaphase plate

All of these
