Are lateral roots endogenous?
In the endogenous type, a lateral root is formed in the pericycle or endodermis of a parent root far from the root apex. An adventitious root initiates in subdermal cells in some species, e.g. Ceratopteris (Hou and Hill, 2002).
Are lateral roots exogenous in origin?
Lateral roots are endogenous in origin as they develop from.
What is exogenous origin?
The term "exogenous" refers to a component of an organism that grows from the outside. The stem's lateral organs, such as leaves and branches, are exogenous.
What are endogenous roots?
In vascular plants two patterns of root branching are generally found, endogenous and exogenous. In the endogenous type, a lateral root is formed in the pericycle or endodermis of a parent root far from the root apex.
Why roots are endogenous?
Because lateral roots are initiated in the pericycle and grow out through the cortex and epidermis, they are said to have an internal, or endogenous, origin, in contrast to the external, or exogenous, origin of leaves and the apical meristem of stems (see below Stems).
What is exogenous root?
The cells of the root hair arises from the epidermis of the root tissue. Thus, it is exogenous in origin . While the cells of the lateral roots arise from the pericycle, which is endogenous.
What are exogenous and endogenous roots?
what is endogeneous and exogeneous? Here endogenous means lateral roots are derived or originates from within an organism, tissue, or cell. Exogenous means root hairs are derived or originates externally from an organism, tissue, or cell.Mar 8, 2014
What are endogenous lateral branches?
The parts which arise from the pericycle are called endogenous origin. The lateral roots or root branches originate endogenously as they originate from the pericycle. So, the correct answer is 'Root branches are endogenous'
Why are lateral roots endogenous?
Because lateral roots are initiated in the pericycle and grow out through the cortex and epidermis, they are said to have an internal, or endogenous, origin, in contrast to the external, or exogenous, origin of leaves and the apical meristem of stems (see below Stems).
Are branches exogenous or endogenous?
The stem's lateral organs, such as leaves and branches, are exogenous. The leaf is a stem-borne, lateral structure that is typically flattened. Leaves are formed by the shoot's apical meristems.
What is lateral branches?
A lateral branch is any branch that grows from the trunk of a tree or along the length of any other branch. Thus, while a major branch growing from the trunk of a tree is itself a lateral branch, the branches growing from that lateral may themselves have laterals, and so forth throughout the tree.
