Plants exhibit two types of growth: primary and secondary.
Primary growth refers to growth which helps in elongation of the plant.
It helps the plant grow both ways upwards and downwards.
Meristems play a key role in this type of growth, they are capable of rapid cell division.
The type of meristem which is key for primary growth is apical meristem (found at the apex/ tips of plants).
The growth at the apical meristem increases the length of the plant in two ways:
- at the topmost tip of the stem , making the plant longer.
- and at the root , thereby enabling the plant to grow longer in the downward direction.
