Petals- The petals (which are usually bright or bold in color) are the part of the flower that usually catch our eye when we
first look at it. They catch bees' eyes, too! They are what attract the bees to the flower.
Sepals- Parts that look like little green leaves that cover the outside of a flower bud to protect the flower before it opens
Pistil- The pistil is the female part of the flower. It includes the stigma, the style, the ovary, and the ovules
stigma- the tip of the pistil that receives male pollen grains
style- the long stalk that the stigma sits on top of
ovary- has the seeds inside and turns into the fruit that we eat
ovules- the part of the ovary that becomes the seed
Stamen- The stamen is the male part of the flower. It is made up of the anther and the filament.
anther- yellow, pouch-like part inside of the flower that holds pollen grains. It is usually on top of a long stalk
that looks like a fine hair
filament- This is the fine hair-like stalk that the anther sits on top of.
