Water plants float on water bodies but still can respire as they have stomata largely on upper side of the leaves ( adaxial surface) and either have broad leaves or serrated leaves.
Plants wait for insects to visit their pitcher like structure and close the lid and digest the insect to meet their protein needs.
Plants resemble stones if they have to grow in deserts . Can you recognise plants from pebbles in this picture ?








Nature has plants designed to go upto 14,000 feet and above MSL . Even you can decide the altitude based on plant formations. Pines which are trees from 3500 feet to 4500 feet will not be found at 6000 feet but you will find the Cedrus on that height.
Pines have special female cones which protect seeds from snow and cold temperatures.

Over 16 million people displaced in one country, millions displaced in another, due to deforestation on the banks of their rivers and almost all the lakes world over especially in developing world or in semitropical and tropical conditions and especially fragile ecosystem are gone. Europe suffered over 30 degree for weeks with erratic winter, Russia once know for its cold is burning with heat wave, almost millions of people are suffering world over. I dont know what is green house effect and how does it influence the global warming ( scientific debates on yes or no about this ) but I know if plants are not there human beings cant survive. Lay more emphasis on preventing deforestation , promote plantations on the hills river banks and people will live.
