Blood vessels, both large and small, course through connective tissue, which is therefore closely associated with the nourishment of tissues and organs throughout the body.
Is connective tissue cellular or fibrous?
In some areas, the connective tissue is loosely organized and highly cellular; in others, its fibrous components predominate; and in still others, the ground substance may be its most conspicuous feature.

Different vitamins used are thiamine (vitamin B 1 ), nicotinic acid (vitamin B 3 ), adenine (vitamin B 6 ), riboflavin (vitamin B 2 ), pantothenic acid (vitamin B 5 ), biotin (vitamin H), folic acid (vitamin M) and myo-inositol. The most important vitamins for your plants are ' Thiamine ' and ' Myo-inositol '. All other vitamins are not essential and we need them in tissue culture for specific benefits only based on the requirements.
