In prokaryotes there is single multifunctional fatty acyl synthase sufficient for complete fatty acid synthesis whereas in eukaryotes there are many different enzymes involved in the fatty acid synthesis. The probable explanation for this difference is: Fatty acid synthesis is more stringent in eukaryotes For better regulation of fatty acid synthesis in eukaryotes Synthesis of fatty acid is by different mechanism in eukaryotes as compare to prokaryotes Fatty acids of eukaryotes are different from the prokaryotesCarrying capacity of a forest is 20 tones which increases 10 % of its biomass annually.
