What part of a flower produces pollen quizlet?
How does a flower make pollen?
Flowers have male parts called stamens that produce a sticky powder called pollen. Flowers also have a female part called the pistil. When pollen from a plant’s stamen is transferred to a different plant’s stigma, it is called cross-pollination. Cross-pollination produces stronger plants.
What flowers have no pollen?
Flowers like camellias, lilies, and roses, do not have pollen that is dispersed by the wind and they generally do not affect people with hay fever. However, some highly fragrant flowers that do not aggravate allergies can still be an irritant with their potent scents.

What does a sepal look like?
They have colorful sepals that look like petals. A sepal is a leaflike flower part that is the outermost whorl of a flower. Usually it is green and can be found underneath the petals. The sepal is the part that encases and protects the flower when it is in the bud stage./span>
Do all flowers have sepals?
The inner parts of the ovary have small bead like structures called ovules. Even If the petals of a flower are joined together, the pistil need not necessarily be joined to the petal. Not all flowers have sepals, petals, stamens and pistils.

Can plants change gender?
Like animals, plants have gender. In almost all plants, sex is constant, but in a few species, individual plants may change their sex. This is called environmental sex determination (ESD). But in this maple species, severe damage to branches and leaves of male trees caused them to flower as females two years later./span>
