Root 1
A root that arises from an organ other than the root
Adventitious root
a type of adventitious root that grows from the stem or leaves aboveground
Aerial Root
The first layer of cells inside the epidermis
Protective tissue consisting of tightly packed cells that make up the epidermis or external covering of leaves, stems, and roots.
Dermal tissue
The innermost layer of the cortex that consists of tightly fitting cells
Endodermis
A root system that has no dominant primary root but is made of many primary and secondary roots of similar size.
fibrous root system
Fundamental tissue consisting of cell groups found in all parts of a plant other than dermal or vascular tissues.
Ground tissue
A smaller root that grows horizontally from the primary root
Lateral root
Mutualism
The outermost part of the stele that borders the cortex and consists of a layer of parenchyma or sclerenchyma cells
Pericycle
A single root initiated in the embryo within the seed
Primary root
A special layer of tissue that functions to protect the tip of a root
Root cap
A long, narrow epidermal cell that grows perpendicular to the surface of the root greatly increases the area of the root and thereby increases the absorption of water and minerals.
Root hair.
The 1 centimeter at the end of the root that consists of young tissues, including the root cap, quiescent center, and subatomic particles.
Root tip
The central part of a root or stem of vascular plants made up of the pericycle, the vascular tissue, and ground tissue, such as pith.
Stele
A large, central, and dominant root from which lateral roots or secondary roots develop.
Taproot
A root system composed of one main primary root and many secondary roots branching off the primary root.
Taproot System
The meristematic tissue that produces xylem and phloem to the other
Vascular Cambium
A group of cells that make up the connective vessels of the plant. Zone of cellular division: the location of the root apical meristem in the root tip where cell division results in the primary growth of the root.
Vascular Tissue
The region in the root tip where cell derived from the apical meristem increase in length.
Zone of Cellar Elongation
The area in the root tip where the cells take on specific functions.
Zone of Cellular Maturation
