Five practice questions, worked

Original questions written to this exam's published syllabus and pattern. Not past papers.

1. Cyclophysis in vegetative propagation refers to:

  1. Change in a propagule's behaviour with the age of the meristem it came from
  2. Persistence of branch-like growth linked to the propagule's position on the tree
  3. Variation arising in plants regenerated through a callus phase
  4. Suppression of lateral buds by the leading shoot of a tree
Answer and working

A. Change in a propagule's behaviour with the age of the meristem it came from

Cyclophysis is the effect of meristem age (maturation). Position-linked persistence of branch habit is topophysis; callus-derived variation is somaclonal variation; bud suppression by the leader is apical dominance.
