Pollination can occur within the plant of the same flower, different species of the same flower or the different flowers. As a result, most wind-pollinated flowers are green or dull-colored. Instead, the male flowers grow in clusters with short stems that break off and float to the surface of the water. Some examples of water pollinated flowers are as follows: • Water hyacinth is a water pollinated flower because of the following reasons: • They have no bright colours or special odours. The pollen grains are kept above the water, where they are transported via floating male flowers that plow into female flowers to effect pollination. The pollinating agents are birds, animals, water, wind and insect. Wind and water pollinated flowers are light in weight as air and water cannot carry heavy pollens. It is a process before fertilization of flower. Characteristics of Insect pollinated flowers: 1. This is called surface hydrophily, but is relatively rare (only 2% of pollination is hydrophily). Wind-pollinated plants don’t normally have flowers, but when they do they are small, don’t have perfumes or nectar, produce large amounts of light pollen, have stamens and stigmas exposed to air currents to either catch or distribute pollen and don’t normally have flower petals.
