The Key Contents from this Module are:

Embryogenesis is defined by a sequential series of dynamic processes that include cell division and growth

Two steps involved in Embryogenesis are:

Induction of embryogenesis
Development of embryo


Factors affecting somatic embryogenesis include:
Nutrient medium
Light
Gases

Some applications of somatic embryogenesis are:
Micropropagation
Secondary metabolite production
Model for the study of organd differentiation and regulation
Germplasm conservation a form of synthetic seed technology, is a method to conserve the genetic traits of endangered and commercially valuable species
Two major types of Germplasm conservation are:
In-situ preservation
Ex-situ preservation

Cryopreservation is the process of cooling and storing cells, tissues, or organs at very low temperatures to maintain their viability.
 
The sum of all the chemical reactions that take place in an organism is call metabolism
Primary metabolites are those; that are directly involved in normal growth, development, and reproduction in plants., such as lipids, proteins, nucleic acids, etc.
Secondary metabolites are numerous chemical compounds produced by the plant;cell through metabolic pathways derived from the primary metabolic pathways. They can be divide into three chemically distinct groups namely:

Terpenes
Phenols
Nitrogen-containing compounds
