NUCLEUS
A TYPE OF CELL THAT LACKS MEMBRANE - BOUNDED NUCLEUS.
EXTREMELY MICROSCOPIC RANGING FROM 1- 10UM IN DIAMETER.
PROKARYOTES
THE BASIC MORPHOLOGICAL AND PHYSIOLOGICAL UNIT OF LIFE;
ABLE TO CONROL AND EXECUTE SEVERAL FUNCTIONS;
CELL STRUCTURES CAN ONLY BE OBSERVED UNDER “HIGH MAGNIFICATION ELECTRON MICROSCOPE.”
CELL
CELL STRUCTURES ARE SEPARATED INTERNALLY INTO NUMEROUS MEMBRANOUS COMPARTMENTS CALLED…
ORGANELLES
ORGANELLES …
BIOSYNTHESIS; SECRETION; STORAGE; DIGESTION; RESPIRATION; REPRODUCTION
EU ?
TRUE
A TYPE OF CELL CONTAINING A DISTINCT MEMBRANE BOUNDED NUCLEUS;
MORE COMPLEX AND LARGER IN SIZE WITH 10-100UM IN DIAMETERS.
EUKARYOTES
KINGDOMS OF EUKARYOTES (4)
ANIMALIA (METAZOA) ;
PLANTAE;
FUNGI; AND
PROTISTA
ONLY FOUND IN EUKARYOTIC CELLS;
STORES THE CELL’S HEREDITARY DNA AND CONTROLS CELLULAR ACTIVITIES LIKE GROWTH, METABOLISM, PROTEIN SYNTHESIS AND REPRODUCTION.
NUCLEUS
ARE CELLULAR BUNDLES MADE UP OF COMPLEX MACROMOLECULES OF “DNA”, “RNA”, AND “PROTEIN”.
CHROMATIN
SYNTHESIZE PROTEINS IN THE CYTOPLASM AND OTHER ORGANELLES “NOT DERIVED FROM THE ENDOMEMBRANE SYSTEM.”
FREE RIBOSOMES
SYNTHESIZE MEMBRANE PROTEINS, “FOUND IN THE ENDOMEMBRANE SYSTEM” AND PROTEINS DESTNED “FOR EXPORT” FROM THE CELLS.
MEMBRANE-ASSOCIATED RIBOSOMES
IT IS A “GROUP OF MEMBRANES” AND ORGANELLES IN EUKARYOTIC CELLS THAT WORKS TOGETHER TO MODIFY, PACKAGE, AND TRANSPORT LIPIDS AND PROTEINS.
ENDOMEMBRANE SYSTEM
ENDOMEMNRANE SYSTEM INCLUDES:
ENDOPLASMIC RETICULUM; GOLGI APPARATUS; LYSOSOMES; VESICLES; PLASMA MEMBRANE; NUCLEAR ENVELOPE
