What is the lateral part of the plant?
Secondary, or lateral, meristems, which are found in all woody plants and in some herbaceous ones, consist of the vascular cambium and the cork cambium. They produce secondary tissues from a ring of vascular cambium in stems and roots.
Where is the lateral root on a plant?
In seed plants, lateral root initiation (LRI) typically takes place close to the meristematic region in the root tip in an internal cell layer called the pericycle.
What are lateral roots called?
…the taproot are produced smaller lateral roots (secondary roots) that grow horizontally or diagonally. These secondary roots further produce their own smaller lateral roots (tertiary roots).
Where do lateral roots form from?
Lateral roots originate from a subset of pericycle cells situated in front of the xylem poles (Dolan et al., 1993). Since the pericycle is located deep within the root, new primordia have to break through the three overlying outer layers of cells (Fig. 2B.).Jul 27, 2009
What is the function of lateral in plants?
Lateral meristems are the meristems that are present at the longitudinal axis region of the roots and shoots of the plants. The function of lateral meristem is to increase the thickness of the plants.
What is lateral in plants?
In tissue: Plants. Secondary, or lateral, meristems, which are found in all woody plants and in some herbaceous ones, consist of the vascular cambium and the cork cambium. They produce secondary tissues from a ring of vascular cambium in stems and roots.
What are lateral sides of plants?
Lateral Meristems – The lateral meristems are present on the lateral side of the stem and root of a plant. These meristems help in increasing the thickness of the plants. The vascular cambium and the cork cambium are good examples of a lateral meristematic tissue.
What is apical and lateral?
In a plant we can see three types of meristematic tissues: apical meristem, intercalary meristem and lateral meristem. Apical meristem is found in the tips of roots and shoots. Intercalary meristem is located at the leaf blades and base of nodes in stems. Lateral meristem is found in the woody part of the plants.
What is the functions of lateral meristem?
Lateral meristems are known as secondary meristems because they are responsible for secondary growth, or increase in stem girth and thickness. Meristems form anew from other cells in injured tissues and are responsible for wound healing.
What are the functions of meristems?
Meristems actively split the tissues of the plant. Meristematic tissue also generates secondary tissues such as wood and cork. The plant develops through both primary (expansion) and secondary (thickness) growth. These are caused by meristematic tissue.
What are the function of lateral and intercalary meristem?
The intercalary meristems help in increasing the length of the internode. This is usually seen in monocotyledonous plants. Lateral Meristems – The lateral meristems are present on the lateral side of the stem and root of a plant. These meristems help in increasing the thickness of the plants.
