Corona in Biology

Corona is a term used in biology to describe structures that resemble a crown or halo. It is often used to describe the crown-like appearance of certain structures, such as the corona radiata in the human brain or the corona of the sunflower.

Corona Radiata

The corona radiata is a structure in the human brain that consists of several layers of cells surrounding the oocyte in the Graafian follicle. These cells are important for providing essential nutrients to the oocyte and for supporting its development.

Corona of a Sunflower

The corona of a sunflower refers to the ring of petals that surrounds the central disc florets. This structure is often brightly colored and serves to attract pollinators, such as bees and butterflies, to the flower.
