Term
Cell
Definition
COLLECTION OF LIVING MATTER ENCLOSED BY A BARRIER THAT SEPERATES THE CELL FROM ITS SURROUNDINGS; BASIC UNIT OF ALL FORMS OF LIFE
Term
Cell Theory
Definition
THE IDEA THAT ALL LIVING THINGS ARE COMPOSED OF CELLS, CELLLS ARE THE BASIC UNITS OF STRUCTURE AND FUNCTION IN LIVING THINGS, AND NEW CELLS ARE PRODUCED FROM EXISTING CELLS

Term
Nucleolus
Definition
SMALL, DENSE REGION WITHIN MOST NUCLEI IN WHICH THE ASSEMBLY OF RIBOSOMES BEGINS
Term
Cytoskeleton
Definition
NETWORK OF PROTEIN FILAMENTS WITHIN SOME CELLS THAT HELPS THE CELL MAINTAIN ITS SHAPE AND IS INVOLVED IN MANY FORMS OF CELL MOVEMENT
