Flowers are the key to a plant's identity
The
parts of a flower are:
PETALS
All petals togtehr
are called the COROLLA. This is the showiest, colorful part of the flower.
SEPALS
Leaf-like struture
that encloses the flower before it opens. All sepals togtehr make up the CALYX.
PISTAL
The female flower
part. It is located at the center of the flower. Pistals consist of an ovary containing ovules and one or more
styles, each supporting a stigma. Pollen from another plant lands on a stigma and travels down the style to fertilize
the ovules into seeds. The ovary becomes the fruit.
STAMENS
The male flower
part. This is just inside the petals. It consiste of a filament supporting the anther where the pollen is found.
Most cultivated
plants contain both male and female parts. But there are certain plants that are male or female. Examples are:
corn, asparagus and cucumber.
The time of day affects plants and their
growth
Water movement in plants
varies with the time of day.
At midday, the Stomata are open, and
water moves rapidly through the plant.
Water movement stops at
night, when the Stomata are closed and there is no Transpiration
