Largest flower is that of
A) Sunflower
B) Rafflesia
C) Nelumbo
D) Drosera

Answer 1

Hint: Flower is also called bloom or blossom. It is the reproductive part of any flowering plants or angiosperms. Flowers consist of reproductive organs (Androecium – male part and Gynoecium – female part) and accessory parts (sepals, petals, receptacle).

Complete answer:
>Rafflesia is the largest flower in the World ever recorded.
>Rafflesia is a genus of parasitic flowering plants.
>It was first discovered by French surgeon and naturalist Louis Deschamps in Java.
>Rafflesia belongs to the family Rafflesiaceae.
>Genus Rafflesia consist approximately 28 species.
>It is mainly found in Southeast Asia mainly in Malaysia, Thailand, Indonesia and Philippines.
Characteristics:
>This plant has no stems, leaves and roots.
>It is the holoparasite of vines. Red coloured, five-petalled flowers are the only part of the plant that can be seen outside the host vine.
>The flower smells and looks like rotting flesh. That's why its local name is ‘meat flower’ or ‘corpse flower’.
>This odour attracts insects which help in pollination.
>Most species are hermaphrodite flowers (having both the male and female sexes in one flower) but many species have separate male and female flowers.
Therefore, above we have seen that the largest flower is Rafflesia.
Hence, option B is the correct answer for this question.
Note: Rafflesia was named after the name of British colonialist Sir Stamford Raffles in the early 19th century. This is the endoparasite and absorptive organ of vines.
