WITHIN THE BLOOD
WHAT ARE FIBROUS CELLS?
LONG AND THIN CELLS LIKE THREADS/FIBERS
WHERE ARE FIBROUS CELLS FOUND?
IN THE SKELETAL MUSCLES USE FOR CONTRACTION
WHAT ARE THE THREE MAIN COMPARTMENTS OF A CELL?
PLASMA MEMBRANE - NUCELUS - CYTOPLASM
WHAT IS THE PLASMA MEMBRANE?
THE MEMBRANE AROUND THE OUTSIDE OF THE CELL
WHAT IS THE NUCELUS?
THE CONTROL CENTER OF THE CELL
WHAT IS THE NUCLEOLUS?
STRUCTURE INSIDE NUCELUS HAT PRODUCES RIBSOMES
WHAT IS THE CYTOPLASM?
EVERYTHING THAT IS INBETWEEN THE PLASMA MEMBRANE AND THE NUCELUS
WHAT IS CYSTOLE?
THE LIQUID FOUND WITHIN CELLS
INTRACELLULAR FLUID
WHAT DOES CYTO MEAN?
OF THE CELL
WHAT LIVE INSIDE THE CYTOPLASM?
THE ORGANELLS
WHAT DOES THE NUCLEUS CONTAIN?
THE DNA AND THE NEUCLEOULUS
WHAT IS THE FUNCTION OF THE PLASMA MEMBRANE?
A SEMI PERMEABLE BARRIER CONSISTING OF PHOSPHOLIPID BILAYER
WHAT IS INSIDE THE PLASME MEMBRANE?
LIPIDS - LIPID BILAYER - CHOLESTEROL - PROTEINS - CARBOHYDRATES - MICROVILI - CILIA
WHAT DO THE PHOSPHOLIPIDS DO IN THE MEMBRANE?
ALLOWS LIQUID SOLUBLE SUBSTANCES TO DISSOLVE THROUGH THE MEMBRANE
WHAT DOES THE PHOSPHOLIPID BILAYER DO IN THE MEMBRANE?
KEEPS IONS, PROTONS AND OTHER MOLECULES WHERE THEY NEED TO BE
WHAT DOES THE CHOLESTEROLE DO IN THE MEMBRANE?
HELPS TO REGULATE THE STIFFNESS OF THE MEMBRANE
WHAT DO THE PROTEINS DO IN THE MEMBRANE?
TRANSPORTS LARGER AND IONISED SUBSTANCES THROUGH THE BILAYER
WHAT DO THE CARBOHYDRATES DO IN THE MEMBRANE?
FORMS A SUGARY COAT CALLED GLYCOCALYX AROUND MEMBRANE WHICH TAHS THE CELL
WHAT DOES THE MICROVILI DO FOR THE MEMBRANE?
A SURFACE AREA EXTENSION OF THE CELL WHICH IS INVOLVED IN ABSORBTION
WHAT DOES THE CILIA DO FOR THE MEMBRANE?
WHIP LIKE EXTENSIONS OF THE MEMBRANCE THAT MOVES SUBSTANCES ALONG THE SURFACE OF THE CELL
WHAT ARE ORGANELLES?
SPECIAL STRUCTURES WITHIN THE CELL THE PERFORM SPECIFIC FUNCTIONS
WHAT ARE THE 6 MAIN ORGANELLES?
NUCELUS - ENDOPLASMIC RETICULUM - RIBOSOMES - GOLGI COMPLEX - LYSOSOMES - MITOCHONDIRA
WHAT IS THE ENDOPLASMIC RETICULUM?
SYSTEM OF INTERCONNECTED CHANNELS CALLED CISTERNAE ENCLOSED BY A UNIT MEMBRANE
WHAT IS THE FUNCTION OF ENDOPLASMIC RETICULUM?
SYNTHESIS OF FATTY ACIDS, STEROIDS, PHOSPHOLIPIDS & PROTEINS OF PLASMA MEMBRANE, ALSO DETOXIFICATION OF ALCOHOL AND DRUGS
WHAT ARE THE RIBOSOMES?
CONNECT AMINO ACIDS TOGETHER TO MAKE POLYPEPTIDE CHAINS
WHAT IS THE GOLGI COMPLEX?
CONSISTS OF 3-20 CISTERNAE, SMALL CURVED FLATTENED MEMBRANOUS SACS WITH BUDGING SWOLEN EDGES RESEMBLING A STACK OF PITA BREADS
WHAT IS THE FUNCTION OF GOLGI COMPLEX?
PACKAGES PROTEINS AND DECIDES IF THAT PROTEIN STAYS IN THE CELL OR LEAVS THE CELL
WHAT ARE LYSOSOMES ?
MEMBRANE ENCLOSED VESSELS FROM THE GOLGI COMPLEX THAT CONTAIN POWERFULL DIGESTIVE AND HYDROLYTIC ENZYMES
WHAT DO THE LYSOSOMES DO?
INTRACELLULAR DIGESTION, AUTOLYSIS OF CELL DEATH, AUTOPHAGY OF OLD ORGANELLES, BREAKS DOWN STORED GLYCOGEN
(CELL ASSASIN)
WHAT DOES AUTO MEAN?
SELF
WHAT DOES PHAGY MEAN?
EATING
WHAT DOES LYSIS MEAN?
KILLING
WHAT ARE THE MITOCHONDIRA?
A MEMBEROUS CELL CONSISTING OF A INNER AND OUTER MEMBRANE,
WHAT DOES THE INNER MITOCHONDIRA MEMBRANE DO?
A FUNCTIONAL BARRIER THA ASSISTS WITH ELECTRON TRSNASPORT AND ATP SYNTHESIS
WHAT DOES THE OUTER MITOCHONDIRA MEMBRANE DO?
FULLY ENCLOSES INNER MEMBRANE THAT HAS PROTEIN BASES PORES THAT ALLOW PASSAGE OF LARGE IONS AND MOLECULES
WHAT DOES THE MITOCHONDIRA DO?
PROVIDES ATP THRIGH AEROBIC ABSORPTION
WHAT IS THE CYTOSKELETON?
A NETWORK FO PROTEIN AND FILLAMENT THAT EXTENDS THROUGHOUT THE CYSTOLE
(BONES OF THE CELLS)
