Why doesn't mowing grass damage the meristem and inhibit growth in height, but pruning a shrub does?
What will be an ideal response?
ANSWER: Unlike in eudicots where the most active growing region is internodes nearest a stem apex,
in grasses cell division is limited to a meristematic region at the base of the internode.
Damaging the apical meristem of a eudicot will result in branching rather than growth in
height. Mowing does not damage the meristem, so the grasses grow in height rapidly after
damage.
