What is a bract?

A bract is defined as a modified or specialized leaf that is typically associated with a flower or an inflorescence. These structures often serve several purposes, including providing support for the flower, attracting pollinators, or protecting the flower bud as it develops. Bracts can be colorful and visually prominent, sometimes resembling petals, which can lead to confusion in their identification.

For instance, in some plants, bracts can take on the appearance of petals and can be essential for attracting pollinators. This adaptation helps in reproduction by enhancing visibility and attractiveness to pollinators. Depending on the species, bracts can also perform protective roles, shielding the developing flowers from environmental factors.

Understanding the function and characteristics of bracts is crucial in plant identification, especially when distinguishing them from other plant structures such as flowers, stems, or root systems.
