Biology class 9 pollination chapter
1)Ornithophily?or bird pollination?is?the pollination of flowering plants?by?birds. This coevolutionary association?isderived from insect pollination (entomophily) and?is?particularly well developed in some parts of the world, especially in the tropics and on some island chains.2)In organic chemistry, an?electrophile?is a reagent attracted to electrons.Electrophiles?are positively charged or neutral species having vacant orbitals that are attracted to an electron rich centre. It participates in a chemical reaction by accepting an electron pair in order to bond to a nucleophile.3)Artificial pollination?occurs when humans intervene with the naturalpollination?process. They carry pollen, or plant sperm, from one flower to another, allowing the pollen to fertilize the ovaries and create seeds that will develop into fruits and new plants. Hope it might help u
