The root cap originates from the apical meristem in the plant. The root cap is directly responsible for gravity perception in the plant.

How is the shoot apical meristem different from the root apical 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
What is the function of the root cap-?
A root cap is a small cone of cells that protects the growing part of a root as it makes its way through the soil, the root cap is found covering the tip of a root. Right behind the root cap is the part of the root where most of the root's growth occurs.
The area of active cell division in the onion root tip is called the?
Apical meristem
In which region of a root do you find undifferentiated cells?
the undifferentiated cell is located in the ground meristem region.
External parts of the roots?
Primary root- originates at germination stage from the radicle of the seed.Secondary root- arise from the primary root.root cap- envelope and protects the young roots.root hairs- ensure efficient absorption of nutrients............that's all........
What is a stem apex?
The point of the root meristem is called the root apical meristem, or the apex. The apex of the root meristem is covered by the root cap, which protects and guides its growth trajectory.
What is a root apical meristem protected by?
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.
How does the root cap assist in the growth of root?
The root cap protects the meristem which is the dividing part of the root, it allows the root to push forward into the soil without endangering the meristem. the cells also produce a 'slime' the allows easy movement through the soil.
How is the shoot apical meristem different from the root apical 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
What are the parts of a fibrous root?
root cap: is a section of tissue at the tip of a plant root meristem: is a tissue in a most plant consisting undifferiantiated cells
What is the function of the root cap-?
A root cap is a small cone of cells that protects the growing part of a root as it makes its way through the soil, the root cap is found covering the tip of a root. Right behind the root cap is the part of the root where most of the root's growth occurs.
What is growth tissue that remains just behind the root tip?
the apical meristem
Where is a meristem often found?
An apical meristem is of each root tip is a dividing zone that forms new cells in two directions. The meristem produces new cells in front of itself that become a loose fitting rootcap. Layers of cells in this cap are continually brushed off as the root elongates between soil particles. The cap is perpetually renewed by tiers od cells being formed and pushed down from the meristem.
What is the plant root system made of?
The plant root system is made of various regions of tissues. These are root cap at the apex, the meristem of actively dividing cells, root hair zone and cell elongation and maturation zone having vascular tissue etc.
What happens in meristem regions of plants?
These regions, where cells continuously divide, are where plant growth originates.
What does mitotic activity at the meristem root accomplish?
Primary growth
What is the primary growth of a root?
The very tip of the root is the root cap, a thimblelike cone of cells that protects the delicate, actively dividing cells of the apical meristem. The root's apical meristem has two roles: It replaces the cells of the root cap that are scraped away by the soil, and it produces the cells for primary growth. Cells produced during primary growth form three concentric cylinders of developing tissue (Figure 20-13). The outermost cylinder develops into the dermal tissue of the root. The middle cylinder-the bulk of the root tip-develops into the root's cortex (ground tissue). The innermost cylinder becomes the vascular tissue. -Exploring life, Biology Textbook
