Question

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

Answer 1

ANSWER :

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.

Answer 2

Answer:

This is because of its monocotyledonous characteristics.

Explanation:

Maize is an "excellent example" of monocotyledonous plant. One of the main characteristics of monocot plants is that monocots lack the most essential part – the cambium, which is responsible for secondary growth in plants. Cambium is the "most important part" of the plant stem, which provides growth to the plant’s girth. The absence of the cambium in maize is the reason why the "girth of a maize plant" does "not increase" over a period of time.
