The document explains organogenesis and somatic embryogenesis in plants, outlining the processes involved in forming new organs and embryos, respectively. Organogenesis is described as the formation of shoots or roots from explants, while somatic embryogenesis occurs from somatic cells, involving steps such as dedifferentiation and redifferentiation. Key differences between the two processes are highlighted, along with factors affecting organogenesis.

ORGANOGENSIS SOMATIC EMBRYOGENSIS
Definition It is the formation of new organs like shoots
or roots.
Somatic embryogenesis is the formation
of an embryo from a single somatic cell
Natural or
Artificial
It occurs naturally every day till the plant
lives. It can be done artificially, also.
It can be done artificially only.
Source It can develop from either a callus or an
explant.
It develops from a somatic cell, which is
otherwise not involved in embryo
formation.
Steps
involved
It involves two different steps:
• Dedifferentiation, which results in the
formation of callus.
• Redifferentiation, which results in
development of primordia.
It involves five different steps:
• Initiation
• Proliferation
• Pre-maturation
• Maturation
• Plant development
