Leaf

Flattened green outgrowth from the stem of a plant. This is the primary site for photosynthesis.

Stem

The axis of the plant that bears shoots, fruits and roots and also conducts water, minerals and food to other parts of the plant.

Sepal

These are modified leaves (usually green) that encase the developing flower. At maturity, the sepal opens when the flower blooms. The sepals are collectively known as the calyx.

Petal

These are sterile parts of the flower which serve as elements to attract various pollinators to the flower.

Anther

The part of a flower at the top of a stamen that produces pollen.

Filament

The thin tubular part of the stamen that supports the anther on its top where pollen are produced.

Stigma

A female part of the flower that helps capture pollen released from the anther. It may be feathery and branched or elongated to capture the pollen and initiate pollen germination.

Epicalyx

It is an additional whorl of leaflike bracts around the calyx of a flower.
