Golgi apparatus
Golgi apparatus A cytoplasmic organelle which is composed of flattened sacs resembling smooth endoplasmic reticulum. The sacs are often cup-shaped and located near the nucleus, the open side of the cup generally facing toward the cell surface. The function of the Golgi apparatus is to accept vesicles from the endoplasmic reticulum, to modify the contents, and to distribute the products to other parts of the cell or to the cellular environment.
RELATED TERMS--------------------------------------
Nucleus
Plural: nuclei. The compartment of a cell that contains the chromosomes.
Facing
Tooth colored overlay on the visible portion of a crown; may be acrylic, composite or porcelain.
Cell
Fundamental structural unit of all life. The cell consists primarily of an outer plasma membrane, which separates it from the environment; the genetic material (DNA), which encodes heritable information for the maintainance of life; and the cytoplasm, a heterogeneous assemblage of ions, molecules, and fluid.
Environment
The sum of the total of the elements, factors and conditions in the surroundings which may have an impact on the development, action or survival of an organism or group of organisms. The environment is as opposed to genetics. We are the product of our genetic inheritance and our environment.

Glaucoma
A disease of the eye marked by increased pressure within the eyeball. If left untreated, glaucoma can damage the optic nerve and cause loss of vision
Golgi apparatus
Gamete
Sperm and eggs. These cells have the special property of carrying only one copy of each gene instead the two copies that most other cells carry. These cells contribute to the next generation and are also called “germ line” cells.
Gynandromorph
An individual that is a mosaic of male and female structures. The underlying cause is frequently sex chromosome mosaicism, such that some cells are chromosomal females while others are chromosomal males. Mosaic individuals having simultaneous aspects of both the male and the female phenotype.
Genotype
Genotype is the genetic makeup of an individual organism.
Gene
1. A unit of DNA that carries information for the biosynthesis of a specific product in the cell. 2. Ultimate unit by which inheritable characteristics are transmitted to succeeding generations in all living organisms. Genes are contained by, and arranged along the length of, the chromosome. The gene is composed of deoxyribonucleic acid (DNA). Each chromosome of each species has a definite number and arrangement of genes, which govern both the structure and metabolic functions of the cells and thus of the entire organism.
