(i) Prokaryotic Genome:
• Genome are much smaller and simpler.
• Highly repetitive DNA is not found.
• It is without a limiting membrane.
• It is a naked double strand of DNA.
Eukarvotic Geflorne:
• Genome are larger and complex.
• Occurrence of highly repetitive DNA is found.
• It is bounded by nuclear membrane.
• Double strand of DNA is associated with histone proteins.
(ii) Somatic Embryo: Somatic embryos are formed from plant cells other than egg that are not normally involved in the development of embry os, e.g., callus or explant. No endosperm or seed coat is formed around a somatic embryo.
Zygotic Embryo: Zygotic embryo is formed as a result of double fertilization of the ovule, giving rise to two distinct structures; the zygote and primary endosperm nucleus giving rise to the plant embryo and the endosperm which together go on to develop into a seed.
