Which one of the following statements are not true?
1 Pollen grains of some plants cause severe allergies and bronchial afflications in some people
2 Pollination by wind is more common among the abiotic pollinations
3 Honey is made by bees by digesting pollen collected from flowers
4 Wind and water pollinated flowers do not produce nectar and are not very colourful
