Organogenesis and somatic embryogenesis are techniques which help in plant regeneration. Let us look at the differences between them.

|
|
It is the formation of new organs like shoots or roots. |
Somatic embryogenesis is the formation of an embryo from a single somatic cell. |
|
|
|
|
It occurs naturally every day till the plant lives. It can be done artificially, also. |
It can be done artificially only. |
|
|
|
|
It can develop from either a callus or an explant. |
It develops from a somatic cell, which is otherwise not involved in embryo formation. |

It involves two different steps:

It involves five different steps:

FAQs
What is the difference between somatic and zygotic embryogenesis?
Somatic embryogenesis is the formation of an embryo from a single somatic cell, whereas zygotic embryogenesis is the formation of an embryo by the fusion of a male and female gamete.
What is the difference between gametogenesis and embryogenesis?
Gametogenesis is the formation of male and female gametes, whereas embryogenesis is the formation of embryos.
What suppresses somatic embryogenesis?
Excess of phenolic compounds and glycoproteins suppress the development of embryos in somatic embryogenesis.
What are the factors responsible for somatic embryogenesis?
The explant, nitrogen source, carbon source and growth regulators are some factors responsible for somatic embryogenesis.
What are the factors affecting organogenesis?
The source of explant, temperature, culture media and oxygen gradient are some of the factors responsible for affecting organogenesis.
What is Caulogenesis?
Callogenesis is a type of organogenesis by which only shoot initiation in the callus takes place.
What is rhizogenesis?
Rhizogenesis is the type of organogenesis where only root initiation takes place.
What is cytodifferentiation in plants?
Cytodifferentiation is the development of specialized cells from non specialized precursors by giving them specific nutritional and hormonal sources.
Who is known as the Father of plant tissue culture?
Gottlieb Haberlandt is considered the Father of plant tissue culture.
