Exam 1

Front 1

centriole

Back 1

used in cell division/reproduction

Front 2

vacuole

Back 2

stores water, food, wastes, and enzymes

Front 3

lysosomes

Back 3

break down waste material and cellular debris

Front 4

nuclear envelope

Back 4

is a double lipid bilayer that encloses the genetic material in eukaryotic cells.

Front 5

nucleolus

Back 5

is a non-membrane bound structure composed of proteins and nucleic acids found within the nucleus.

Front 6

chromatin

Back 6

the combination of DNA and proteins that make up the contents of the nucleus of a cell

Front 7

nuclear pore

Back 7

are large protein complexes that cross the nuclear envelope, which is the double membrane surrounding the eukaryotic cell nucleus

Front 8

nucleus

Back 8

maintain the integrity of these genes and to control the activities of the cell by regulating gene expression — the nucleus is, therefore, the control center of the cell

Front 9

ribosomes

Back 9

to assemble the twenty specific amino acid molecules to form the particular protein molecule determined by the nucleotide sequence of an RNA molecule.

Front 10

golgi complex

Back 10

It processes and packages macromolecules, such as proteins and lipids, after their synthesis and before they make their way to their destination; it is particularly important in the processing of proteins for secretion

Front 11

microfilaments

Back 11

are the thinnest filaments of the cytoskeleton, a structure found in the cytoplasm of all eukaryotic cells.

Front 12

microtubule

Back 12

Are a component of the cytoskeleton. These rope-like polymers of tubulin can grow as long as 25 micrometers and are highly dynamic.

Front 13

rough endoplasmic reticulum

Back 13

Part of the cell's internal membrane system studded with ribosomes; helps to transport and export materials through and from the cell.

Front 14

smooth endoplasmic reticulum

Back 14

Part of the cell's internal membrane system which helps to transport and export materials throughout the cell and assemble lipid-based components of the cell membrane.

Front 15

cytoplasm

Back 15

is a thick liquid residing between the cell membrane holding all the cell's internal sub-structures (called organelles), except for the nucleus

Front 16

cell (plasma) membrane

Back 16

is a biological membrane that separates the interior of all cells from the outside environment

Front 17

mitochondrion

Back 17

is a membrane-enclosed organelle found in most eukaryotic cells.Mitochondria are sometimes described as "cellular power plants" because they generate most of the cell's supply of adenosine triphosphate (ATP), used as a source of chemical energy
