#anemophilytamil #sriparamakalyanischool #alwarkurichi • Anemophily: Pollination by wind. The wind pollinated flowers are called anemophilous. • The wind pollinated plants are generally situated in wind exposed regions. Anemophily is a chance event. Therefore, the pollen may not reach the target flower effectively and are wasted during the transit from one flower • to another. The common examples of wind pollinated flowers are - grasses, sugarcane, bamboo, coconut, palm, maize etc., • Anemophilous plants have the following characteristic features: • • The flowers are produced in pendulous, catkin-like or spike inflorescence. • • The axis of inflorescence elongates so that the flowers are brought well above the leaves. • • The perianth is absent or highly reduced. • • The flowers are small, inconspicuous, colourless, not scented, do not secrete nectar. • • The stamens are numerous, filaments are long, exerted and versatile. • • Anthers produce enormous quantities of pollen grains compared to number of ovules available for pollination. They are minute, • light and dry so that they can be carried to long distances by wind. • • In some plants anthers burst violently and release the pollen into the air. Example: Urtica. • • Stigmas are comparatively large, protruding, sometimes branched and feathery, adapted to catch the pollen grains. Generally single ovule is present. • Plant produces flowers before the new leaves appear, so the pollen can be carried without hindrance of leaves. • POLLINATION IN SALVIA • • POLLINATION IN SALVIA | TAMIL EXPLANA... • ENTOMOPHILY • • ENTOMOPHILY | TAMIL EXPLANATION • CHEIROPTEROPHILY • • CHEIROPTEROPHILY | TAMIL | SEXUAL REP... • MALACOPHILY • • MALACOPHILY | TAMIL | SEXUAL REPRODUC... • • POLLINATION IN MAIZE • • MAIZE POLLINATION TAMIL EXPLANATION |... • HYPOHYDROPHILY • • HYPOHYDROPHILY TAMIL EXPLANATION | ZO... • ORNITHOPHILY • • ORNITHOPHILY TAMIL EXPLANATION | ADAP... • EPIHYDROPHILY • • EPIHYDROPHILY TAMIL EXPLANATION | VAL... • ZOOPHILY • • ZOOPHILY TAMIL EXPLANATION
