endoplasmic reticulum
sometimes referred to as the subway system of the cell. ER provides what appears to be a membrane bound pathway to either a particular organelle or the cell membrane itself.
cells functions
a. support
b. protection from the environment
ATP (adenosine triphosphate)
is a short-lived molecule which is used to temporarily store energy which cells use to move materials within and out of the cell and to build or repair cellular proteins and organelles.
cell wall
the outer layer of plant and plant-like cells which is composed of cellublose
small, dot-like, structures which have been identified as molecules which assist in the building of proteins. Cells which are producing large amounts of a preotein typically have more ribosomes than other cells.
the fluid enclosed within the cell membrane. Often used to describe both the fluids, organelles. and othe materials within the boundary of the cell membrane.
spheres of various size which may contain food, bastes, or other substances. They are not found in all cells.
cell membrane functions
a. containment of cytoplasm and organelles
b. selectively control movement of substances
peanut-shaped structures which have been identified as the sites of respiration in cells.
cell membrane
the outer layer of animal and animal-like cells. The inner layer of plant and plant-like organisms.
a term applied to structures (membrane bound) found within the cytoplasm which have been indentified as having a specific function.
structures which store energy(choloroplasts), or store compounds such as starch, proteins, and lipids.
is the process where energy is released from food and transferred to a ATP.(adenosine triphosphate)
protein tubes and threads which appear to function as internal support structures of the cell
the largest organelle within the cytoplasm. Within this structure lies the acids which control the functions of the cell itself
Golgi Apparatus
compact folded structure in which single proteins are connected to others. Sometimes describe as the processing, packaging, and secreting site of the cell.
small spherical structures which contain digestive enzymes. The enzymes can be used to destroy materials within the cell if not the cell itself.
