Botanical Accuracy: The difference between stems stalks ...

A stem is a part of the plant that is a central shoot that holds the leaves, branches, flowers, and so on. The true rhubarb stem is a hollow, nearly bamboo-like cylinder, which leads up to a terminal shoot that eventually develops flower buds. A stalk, on the other hand, can be both leaf stalk and the stem of a plant.

Leaf Structure and Function - OpenEd CUNY

A typical leaf consists of a lamina (the broad part of the leaf, also called the blade) and a petiole (the stalk that attaches the leaf to a stem). The arrangement of leaves on a stem, known as phyllotaxy, enables maximum exposure to sunlight. Each plant species has a characteristic leaf arrangement and form.
