Answer 1

Answer 2

Sepal

Step-by-step explanation:

Sepals are mostly green colored leaves like structures that make the outer most whorl in a mature complete flower. The sepals are sterile in nature and do not serve in gamete formation or any other events of sexual reproduction in plants.

The function of sepals is to protect the flower during the bud stage.
