Differences Between Insect Pollinated and Wind pollinated flowers

What is pollination?

Pollination can be defined as the natural process of transferring pollen grains from the anther (male reproductive part) to the stigma (female reproductive part) of a flower. This process can be carried out either within a flower or between flowers of the same plant or flowers of different plants.

Based on the transfer of pollen grains, pollination has been classified into two different types:

  1. Self Pollination –— Self-pollination is the initial type of pollination, which occurs by transferring the pollen grains directly from anther into the stigma of the same flower. Sunflowers and orchids are the best examples of self-pollinated flowers.
  2. Cross-Pollination — Cross-Pollination is the complex type of pollination, during which the pollen grains are transferred from the anther of the flower into the stigma of a different flower. Tulips, dandelions and daffodils are the best examples of a cross-pollinated flower.

Insect Pollinated and Wind pollinated flowers: Differences

Wind pollinated flowers Insect pollinated flowers
Pollinating Agent
The pollinating agent is wind. The pollinating agents are an insect.
Morphological features of a Flower
The wind-pollinated flowers comprise light coloured petals, without a pleasant strong smell. The insect-pollinated flowers comprise brightly coloured petals with a pleasant strong smell.
Pollen Grains
In wind-pollinated flowers, the produced pollen grains are smaller and lighter in weight, which can be carried by the wind easily. In insect-pollinated flowers, the produced pollen grains are larger in size, sticky and spiny which helps the insect to carry the pollen grains.
Stigma is feathery or sticky and found hanging out of petals. Stigma is small and is situated deep inside the petals.
The stamens are long and visible out of petals. Stamens may be small and hidden inside petals.
The anthers are often seen being supported outside the flower The anthers are found deep inside the flower.
The filaments found in these flowers are slender and long. The filaments found in these flowers are strong and short.
Production of Nectar
These flowers do not produce nectars. These flowers produce a lot of nectars.
There is a lot of wastage as more number of pollen grains are produced. There is no wastage as less number of pollen grains are produced.
Type of Flowers
Plants bear only unisexual flowers. Plants bear bisexual flowers.
