Cells

Front 1

endoplasmic reticulum

Back 1

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.

Front 2

cells functions

Back 2

a. support
b. protection from the environment

Front 3

ATP (adenosine triphosphate)

Back 3

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.

Front 4

cell wall

Back 4

the outer layer of plant and plant-like cells which is composed of cellublose

Front 5

ribosomes

Back 5

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.

Front 6

cytoplasm

Back 6

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.

Front 7

vacuoles

Back 7

spheres of various size which may contain food, bastes, or other substances. They are not found in all cells.

Front 8

cell membrane functions

Back 8

a. containment of cytoplasm and organelles
b. selectively control movement of substances

Front 9

mitochondria

Back 9

peanut-shaped structures which have been identified as the sites of respiration in cells.

Front 10

cell membrane

Back 10

the outer layer of animal and animal-like cells. The inner layer of plant and plant-like organisms.

Front 11

organelles

Back 11

a term applied to structures (membrane bound) found within the cytoplasm which have been indentified as having a specific function.

Front 12

plastids

Back 12

structures which store energy(choloroplasts), or store compounds such as starch, proteins, and lipids.

Front 13

respiration

Back 13

is the process where energy is released from food and transferred to a ATP.(adenosine triphosphate)

Front 14

microtubules
microfilaments

Back 14

protein tubes and threads which appear to function as internal support structures of the cell

Front 15

nucleus

Back 15

the largest organelle within the cytoplasm. Within this structure lies the acids which control the functions of the cell itself

Front 16

Golgi Apparatus

Back 16

compact folded structure in which single proteins are connected to others. Sometimes describe as the processing, packaging, and secreting site of the cell.

Front 17

lysosome

Back 17

small spherical structures which contain digestive enzymes. The enzymes can be used to destroy materials within the cell if not the cell itself.
