In plants, every species knows how to tackle the harsh environment, how to store the food into seed, how to tolerate the stress and how to use the natural things to disperse the seed by giving them a small reward sometime. The orchids are beautiful however; they lack food storage tissue in seed for the growth of embryo and require fungus for germin...

Bhendi or okra, scientifically called Abelmoschus esculentus belonging to the family Malvaceae, is commonly known as “lady’s finger”.
