Term
PROKARYOTE
Definition
  • A SIMPLE CELL WITH NO NUCLEUS AND NO MEMBRANE-BOUND ORGANELLES
  • THE GENETIC MATERIAL IS FOUND IN A REGION OF THE CELL KNOWN AS THE NUCLEOID
  • DIVIDES BY BINARY FISSION
Term
EUKARYOTE
Definition
  • CONNTAINS A NUCLEUS, WHICH FUNCTIONS AS THE CONTROL CENTER OF THE CELL AND STORES DNA
  • CAN BE UNICELLULAR OR MULTICELLULAR
  • CONTAINS MEMBRANE-BOUND ORGANELLES
Term
PLASMA MEMBRANE
Definition
  • THE SELECTIVE BARRIER AROUND A CELL COMPOSED OF A DOUBLE LAYER OF PHOSPHOLIPIDS
Term
CELL WALL
Definition
  • A WALL OR BARRIER THAT FUNCTIONS TO SHAPE AND PROTECT CELLS
  • PPRESENT IN ALL PROKARYOTES
Term
RIBOSOME
Definition
  • THE HOST ORGANELLE FOR PROTEIN SYNTHESIS
  • BUILT IN THE NUCLEOLUS
Term
SMOOTH ENDOPLASMIC RETICULUM
Definition
  • A MEMBRANE-BOUND ORGANELLE INVOLVED IN LIPID SYNTHESIS, DETOXIFICATION, AND CARBOHYDRATE METABOLISM
  • LIVER CELLS CONTAIN MANY SER
  • CONTAINS NO RIBOSOMES 
Term
ROUGH ENDOPLASMIC RETICULUM
Definition
  • KNOWN AS ROUGH BECAUSE OF THE PRESENCE OF RIBOSOMES ON THE CYTOPLASMIC SURFACE
  • PROTEINS PRODUCED BY THIS ORGANELLE ARE OFTEN SECRETED BY THE CELL AND CARRIED TO THE GOLGI APPARATUS
