A root apical meristem is protected by a root cap as it pushes through the abrasive soil. The root cap also secretes a polysaccharide slime that lubricates the soil around the tip of the root.
The root cap is the growth tissue that remains just behind the root tip. It protects the delicate meristem as the root pushes through soil and aids in root growth by secreting lubricating substances.
A stem apex refers to the tip of a plant's stem where the newest growth occurs. It is responsible for the plant's upward growth and the production of new leaves and flowers. The stem apex contains meristematic tissue that allows for continuous growth.
Roots in plants typically consist of the root cap, apical meristem, zone of elongation, zone of differentiation, and root hairs. The root cap protects the apical meristem as the root grows, while the apical meristem is responsible for the primary growth of the root. The zone of elongation allows the root to increase in length, and the zone of differentiation is where specialized cells develop to carry out specific functions. Root hairs increase the surface area of the root for better absorption of water and nutrients.
The meristematic region in the stem tip is referred to as the shoot apical meristem. Leaf primordia develop from the lateral flanks of the shoot apical meristem. They curve up during growth and the older larger primordia serve a protective function.
Cells near the apical meristem are generally undifferentiated and actively dividing, while cells far from the apical meristem are often differentiated and specialized for specific functions. This means that cells near the apical meristem are smaller in size and have thin cell walls, whereas cells far from the meristem are larger and more specialized in structure and function. Additionally, the cells near the apical meristem may have fewer organelles and vacuoles compared to those far from the meristem.
The main difference betweem root and shoot apical meristem is that in case of root apical meristem dermatogen and periblem fuses at apex and give rise to calyptrogen which is responsible for the formation of root cap

Meristem cells undergo multiple divisions for apical growth at the tips of stems. These cells are found in the shoot apical meristem and root apical meristem of plants, and continuously produce new cells for growth and development.
Apical Meristem
Apical meristem is found at the tip of the root and shoot and is made of cells that divide at a rapid pace. The apical meristem helps the plant to grow up above the soil and down into the ground. This growth is called primary growth.
Cells near the apical meristem are generally undifferentiated and actively dividing, while cells far from the apical meristem are often differentiated and specialized for specific functions. This means that cells near the apical meristem are smaller in size and have thin cell walls, whereas cells far from the meristem are larger and more specialized in structure and function. Additionally, the cells near the apical meristem may have fewer organelles and vacuoles compared to those far from the meristem.
Roots lengthen through cell division at the root tip in the zone of elongation, while shoots lengthen through cell division in the apical meristem located at the shoot tip. The apical meristem is responsible for the growth of new cells and tissues in both roots and shoots, allowing the plant to increase in length.
the undifferentiated cell is located in the ground meristem region.
