1. Most flowers have four parts: ____________, ___________,
______________ (male part) and _____________ (female part).
2. a. Sepals protect the _________________until it opens.
b. Petals attract ______________________________.
c. Stamens make_______________________________.
d. Ovary grows into fruits which contain the _______________.
3. Stamen: Is made up of the ____________ which holds the
____________ grains. The _______________ holds the
_______________ up.
4. Pistil: Contains the _____________, _______________,
_______________ and _________________(eggs).
sepal - the sepals are small leaves located directly under a flower anther - the anther is the tip of a flower's
they are the outermost part of a flower.

filament - the filament is the part of the flower stigma - the stigma is uppermost part of the pistil, the female
reproductive tissue of a flower. The stigma receives the male pollen
that holds the anther (and part of the stamen,
grains during fertilization, when they travel through the style to the
the male reproductive organs of the plant).
