Functions of Apical Meristems
The apical meristem, positioned just below the surface of the outermost branches and roots, continually undergoes division. Some cells divide to produce more meristematic cells, while others divide and specialize into structural or vascular cells. Most plants have two apical meristem locations.
Shoot Apical Meristem
This meristem is found at the tips of plants and has the following responsibilities:
- Shoot growth.
- Phototropism (growth towards sunlight).
Root Apical Meristem
This meristem is located at the tips of roots and has the following functions:
- Sensing the soil conditions around the root.
- Hydrotropism (growth towards water).
- Protects root cap.
Apical Meristem: Meaning and Function
The apical meristem is a group of cells that can divide and help in primary growth. These cells are found at the tips of growing roots and shoots. The apical meristems create the main parts of the plant and make the roots and shoots longer. The apical meristem is located at the root tip, shoot tip, and the tip of the leaves. The meristematic cell can transform into various cell types.
Meristem is the tissue found in the plant’s growth region. The term “apical” indicates that growth occurs at both the top and bottom of the plant. An intercalary meristem is situated between branches and a lateral meristem contributes to the plant’s width, particularly in woody plants.
