Question

The absence of centrioles from higher plant cells means that during somatic cell nuclear division there is :

• A. no apparent organiser of mitotic spindles
• B. no equatorial arrangement of chromo-somes at metaphase.
• C. no new cell wall laid down at telophase.
• D. no spindle formed.

Answer 1

Answer: (A)

Although no centrioles are visible, there is spindle formation and the chromosomes do exhibit equatorial arrangement. Spindle formation is probably by another organelle, unknown as yet.
