The Ginkgo is in the genus Ginkgo and the division Ginkgophyta. It is characterized by fruits that that are fleshy and produce buteric acid. The leaves are fan-shaped and strongly resemble the leaves of maiden-hair fern. These trees are native to China and are now found all over the world because people have carried them there to grow. In Oriental countries they are typically found planted around temples and various shrines.

Girth is a term that is being applied to the way a tree grows. During secondary growth, a tree grows in girth. That means that it increases its diameter by growing in girth.

Glucose is a six-carbon sugar that is one of the primary products of photosynthesis. Glucose is the food that the plant burns to gain energy for metabolism.

Grass leaves have a considerably different morphology than do leaves of most all other plants. Grass leaves are composed of a sheath, blade, auricle and ligule. The sheath is the blade-like portion that acts like the petiole of the leaf, only it is flat and blade-like and surrounds the stem, connecting to the node below. The blade extends at a right angle to the sheath. The ligule is a small tongue-like flat of tissue that extends out from the sheath and parallel to it above the blade and perpendicular to the blade. The auricles are two small flaps of tissue that extend out from the blade and perpendicular to the sheath, partially surrounding the stem.

The ground meristem is one of the primary meristem tissues that differentiates from the apical meristem. The ground meristem differentiates into the the cortex, pith rays, and pith.

The ground parenchyma is the (back)ground parenchyma in the monocot stem. The vascular bundles of monocot stems are scattered and embedded in the ground parenchyma.

The guard cells are are two crescent-shaped cells on either side of the pore of a stoma in the epidermis of the stem or leaf. By changing shape, the guard cells are able to cover and uncover the pore of the stoma and let oxygen out and carbon dioxide into the stem or leaf. Changes in turgor pressure is the mechanism by which the shape of the guard cell is altered so as to cover and uncover the pore.

Gymnosperms are woody plants that are characterized by a many cotyledons (more than two seed leaves) in the seed, net-veined leaves, vascular bundles in a ring, with secondary growth and concentric growth rings.
