Plants are  lot smarter than we thought. According to researchers, they are capable of making intelligent decisions regarding risk. Scientists have discovered that one plant,  humble pea, can make decisions regarding how to survive best, even though it does not have  brain. Researchers from  UK's Oxford University and Israel's Tel-Hai College grew several pea plants that had their roots separated between two pots. Each pot contained differing amounts of nutrients. One pot always had  same amount, while  other pot varied between  lot and  little.  plants turned out to be remarkably consistent at diverting their roots to  pot with  most nutrients. 
 research paper will be published this week in  'Current Biology' journal. Researcher Alex Kacelnik said  experiment, "raises a question, not about plants, but about animals and humans". He wondered whether  pea plant might be more efficient in using its limited decision-making resources than humans. He said: "We have  very fancy brain, but maybe most of  time we're not using it." Professor Kacelnik said he did not think that pea plants were intelligent in  human sense, but that they exhibited complex behaviours to efficiently take advantage of natural opportunities. It would be interesting to see how our lives would be different if we adopted similar strategies.
