Tenzin sem ka beej lagaata hai aur roz tana naapta hai. Wo lamba hota hai aur zyada patte aate hain: paudhe jeevan bhar badhte hain, jaanwaron se kahin zyada.

Wo gamla khidki ke paas rakhta hai. Kuch dinon mein tana roshni ki taraf mudta hai. Wo gamla ghuma deta hai, aur tana phir khidki ki taraf mud jaata hai! Is beech jadein hamesha neeche, mitti aur paani ki taraf badhti hain.

Kuch paudhe tez hilte hain: chhui-mui ka patta chhoo do to seconds mein simat jaata hai. Kuch paudhe, jaise ghada paudha (pitcher plant), kam poshan wali mitti ki kami poori karne ke liye keede bhi pakadte hain.

Bhaarateeya scientist Jagadish Chandra Bose ne sau saal se pehle bahut sanvedansheel yantra banaaye jo dikhaate the ki paudhe sparsh, roshni aur doosre badlaav par kaise pratikriya dete hain.
