Pollination by wind is called as anemophily; the Cannabis plants produce colourless flowers, large number of small pollen grains (around 5 lac pollens from single flower) and have hairy style and stigma. Their flowers are well exposed to air and are produced above the foliage to make them accessible to wind currents. Option A is correctly matched. Pollination by water currents is known as hydrophily; Zostera is characterized by presence of single sessile anther in male flower, dehiscence by water absorption, enormously elongated and needle like pollens. Option B is correctly matched. Pollination of rough, sticky pollens by insects is called as entomophily; Salvia produce nectar/scent/odour in their colourful flowers to attract insects. Option C is correctly matched. Pollination by birds is called as ornithophily; the bird pollinated flowers are colourful, mostly red, produce lots of nectar and also exhibit adaptations to protect nectar from insects. Pollination by bats is termed as chiropterophily; the plants produce large, bell shaped and attractive flowers that open at night and produce strong odours and nectar. Example: Adansonia (produce carrion scent) and Kigelia (opens in day as well as in night and produce strong scent at night).
