Notes / Explanation
The largest flower in the world is the rafflesia, an extraordinary and unusual plant that produces a single enormous flower far larger than that of any other plant. The rafflesia is found in the tropical rainforests of South-East Asia, where it grows in the warm and humid conditions of the forest. What makes this plant so remarkable is not only the great size of its flower, which can grow to a very large diameter and is among the biggest single flowers known, but also its strange way of life and its peculiar characteristics. The rafflesia is unusual because it does not have the ordinary parts that most plants have, such as leaves, stems and roots of the usual kind, and it does not make its own food in the way that most plants do through the green colouring in their leaves. Instead, it lives as a kind of parasite, drawing its nourishment from another plant on which it grows, attaching itself to the host plant and taking water and nutrients from it. For most of its life the rafflesia remains hidden within the tissues of its host plant and is not visible, and it becomes apparent only when it produces its huge flower, which emerges and opens to reveal its great size and its reddish-brown colour marked with paler spots. Another notable and less pleasant feature of the flower is its strong and unpleasant smell, which has been compared to the odour of decaying matter. This smell, however, serves an important purpose for the plant, because it attracts certain insects that are drawn to such odours, and these insects help to carry pollen from one flower to another, which is necessary for the plant to reproduce. The flower remains open for only a short time before it withers. The rafflesia is regarded as one of the wonders of the plant world because of its remarkable size and its unusual habits, and it is of great interest to those who study plants. For PPSC and other competitive examinations, the key points to remember are that the largest flower in the world is the rafflesia, that it grows in the tropical rainforests of South-East Asia, that it lives as a parasite on another plant rather than making its own food, and that its huge flower gives off a strong unpleasant smell that attracts insects which help it to reproduce.
