Question

identifying structures and functions of flowers
what is the function of the sepal?
the sepal fertilizes the egg.
the sepal protects the bud.
the sepal produces pollen.
the sepal disperses the seed.

Explanation:

Sepals are the outermost part of a flower. Before the flower blooms (when it is in the bud stage), sepals enclose and protect the bud. Fertilization of the egg is done by pollen (from the stamen) fusing with the egg (in the pistil). Pollen is produced by the anther (part of the stamen). Seed dispersal is a function related to structures like fruits (which develop from the ovary after fertilization) or other specialized dispersal mechanisms (like wind - dispersed seeds having structures like parachutes).

Answer:

The sepal protects the bud.
