WebMost primary growth occurs at the apices, or tips, of stems and roots. Primary growth is a result of rapidly dividing cells in the apical meristems at the shoot tip and root tip. Subsequent cell elongation also contributes to primary growth. The growth of shoots and roots during primary growth enables plants to continuously seek water (roots ... WebPrimary growth. Lower plants like ferns and horsetails have as growth points apical cells that have the shape of an inverted pyramid or parabolic dish. In higher plants growth does not arise from a single cell, but from growth zones, called meristems, in which groups of dividing cells occur. (Meristems consist of undifferentiated cells that ...

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.
WebStem Growth. The stems of all vascular plants get longer through primary growth. This occurs in primary meristem at the tips and nodes of the stems. Most stems also grow in thickness through secondary growth. This occurs in secondary meristem, which is located in and around the vascular tissues. Secondary growth forms secondary vascular tissues ... WebJan 21, 2024 · Primary growth occurs in areas called apical meristems. This type of growth allows plants to increase in length and to extend roots deeper into the soil. All plants undergo primary growth. Plants that undergo secondary growth, such as trees, have lateral meristems that produce new cells. These new cells increase the thickness of stems and …
