Question

Girth of maize plant does not increase over a period of time justify

Answer 1

In maize plant, the girth is not increased because -

Maize is a monocotyledonous plant.

Cambium is responsible for the widening of girth in plants. Cambium is an example of lateral meristem which helps in growth of the secondary parts of the plant body.

But, monocot plants do not have cambium.

So due to the absence of cambium in maize plant there is no increase in their girth.
