Which flower part is known for attracting insects to assist in pollination?

1. Anther

2. Petals

3. Filament

4. Endosperm

The correct answer is: Petals

The petals of a flower are primarily responsible for attracting insects and other pollinators, playing a crucial role in the pollination process. Their vibrant colors, unique patterns, and sometimes even scent can draw the attention of insects, such as bees and butterflies. This attraction is essential for ensuring that these pollinators visit the flower, facilitating the transfer of pollen from the male anther to the female stigma, which ultimately aids in plant reproduction. In contrast, the other parts listed serve different functions. The anther, for example, is where pollen is produced but does not contribute directly to attracting pollinators. The filament is the stalk that supports the anther, again not involved in enticing insects. The endosperm is part of the seed and provides nourishment to the developing embryo but has no role in the process of attracting pollinators. Thus, petals play a pivotal role in the reproductive cycle of flowering plants by acting as a visual and olfactory lure for pollinators.
