Fan-shaped leaves are leaves that are shaped by an oriental fan, very narrow at the base where the petiole attaches and very broad at the apex. Ginkgo trees are a good example of this type of leaf.

Fasciscular cambium is the portion of the vascular cambium that is derived from the residual procambium within the vascular bundle.

Ferns are in the division Pterophyta and consist of four different orders: Ophioglossales, Pteridales, Salvineales, and Marsileales. The ferns that most people grow in their homes or in their gardens is in the order Pteridales. These ferns are characterized by a rhizome with adventitious roots and leaf branches off of the nodes. Spores are borne on the lower surface of the leaf (frond).

Fibers are one the two types of sclerenchyma. Sclerids are the other cell type. Fibers are very long and narrow with a very small lumen. They are dead when fully mature and functioning. The cell walls contain lignin and therefore take up the red stain. Their function in the plant is strengthening.

Firs are in the genus Abies, the family Pinaceae and the Division Coniferophyta. They are characterized by needle-like leaves, and erect cones whose cone scales fall separately, leaving the central axis of the cone on the tree. That central axis is called a candle.
Flower buds are buds, located at the nodes, that will develop into flowers when they get the signal from the environment that the days are of the right length.

The Kingdom Fungi is characterized by all being heterotrophic and either parasites or saprophytes depending upon the species. They are composed of filaments called hyphae that cluster together into a plant body called a mycelium. The cell wall is composed of chitin.
In the vascular cambium, some cells produce the axial system and other cells produce the radial system of vascular tissue. Those vascular cambial cells that produce the radial system are known as the ray initials and those vascular cambial cells that produce the axial system are known as the
fusiform initials. The fusiform initials are responsible for forming all the conducting and strengthening cells in the xylem and phloem areas of the stem and root.
