I believe that is a plant called Wisteria.
all i really know is that STP (standard temperature and pressure) represents conventional conditions established by IUPAC with T = 273.15 K, P = 1 atm . Now putting these values of temperature and pressure at STP, we can calculate easily volume occupied by 1 mol of gas and which comes out to be 22.4 L. hope this helps
It protects the Earth from harmful solar radiation’s and it regulates heating that is provided by the sun.
