Corolla in passion flower helps the plant in achieving pollination.
1 bat
2 bird
3 wind
4 insect
Explanation:
Corolla in passion flower helps the plant in achieving insect pollination. Passion flower produce regular and showy flowers with distinctive corona. These colourful corona attracts insects when an insects visits a flower, it picks up pollen unintentionally on its body. The next flower they visits is then exposed to this pollen and fertilization take place.

At the time of pollination, the pollen grain of Pinus are
1 one celled
2 two celled
3 three celled
4 four celled
Explanation:
The pollen grains of Pinus at the time of shedding have only two prothallial cells. At the time of pollination the pollen grains of pinus are four celled i.e. two prothalial cells a generative cell and a tube cell. Prothalial cell start to disintegrate before the pollination take place. Two non-motile male gamete developed from generative cells. The pollen grains in pinus are produced in a very large number and they are transported to a very long distance by air.

Flower which is pollinated by wind is characterized by
1 Small, non-scented, colourless flowers
2 Big, scented, coloured flowers
3 Big, non-scented, coloured flowers
4 Big, non-scented, colourless flowers
Explanation:
Flower which is pollinated by wind is chracterised by small, non-scented and colourless flowers because no insects are required for pollination. So, there is no need for the flowers to have such characters which might attract the insects. The windpollinated flowers produce pollen in large number if some pollen grains fail to reach their destination even then there will be viable pollen grains left to pollinate the flower. These pollen grains are light in weight, nonsticky and small, so that they can be easily carried away by wind.
