Exhibition at our school was held on 22nd and 23ed of December. The trained students of class 9 and PI introduced the foldscope to my family members. They were excited to know about this fascinating tool and observed variety of pollen grains of Hibiscus.

Generally petals are brightly coloured to attract the insects for pollination. Red rose petals appear red due to the presence of the pigment anthocyanin.
