CELLULAR MACRO MOLECULES
  • Adenosine diphosphate : A compound with two phosphate bonds the second bond being energy rich forms A.T.P. by the addition of inorganic phosphate.
  • Adenosine triphosphate : A compound containing three phosphate, groups carrying two high energy phosphate for energy require reactions in the cell.
  • Amylase : It is an enzyme that helps to convert starch ( a polysaccharide) into simple sugars (monosaccharides).
  • Amyloplast : It is a colourless plastid storing starch.
  • Carnivore : It refers to the flesh eating animals.
  • Cellular pool : The collection of various types of molecules in a cell is termed as cellular pool.
  • Cytochromes : A group of complex compounds which form a part of the electron transport chain in the cellular oxidation process.
  • Cytochromes : These are the conjugated proteins containing heme. They act as intermediates in electron transport chain.
  • Glyceride : An ester of glycerine.
  • Glycerol : An alcohol with three –OH groups is termed glycerol.
  • Glycogen : A non-reducing, white amorphous polysaccharide formed as a reserve carbohydrate stored in muscles and living cells of animals.
  • Glycogen : A polysaccharide formed of many glucose molecules.
  • Meiosis : Type of cell division occurring in diploid or polyploidy tissues that results in a reduction in chromosome number, usually by half.
  • Middle lamella : Made of magnesium and calcium pectate, it holds the neighbouring cells together.
  • Mitosis : Nuclear division involving exact duplication and separation of chromosome threads so that each of the two daughter nuclei carries a chromosome complement identical to that of parent nucleus.
  • Mitosis inhibitor : Compound that inhibits mitosis.
  • Myoglobin : A conjugated protein found in muscles.
  • Nucleotide : It is a nucleoside joined to phosphate radical.
  • Polynucleotide : It is formed when a number of nucleotides join together by phosphodiester bonds.
  • Procaryotic : (primitive cells) Having no membrane bound organelles as are found in bacteria.
  • Prosthetic group : A non-proteinic group of conjugated proteins.
  • Prosthetic group : It refers to the non-protein group of conjugated proteins.
  • Purine : It is a nitrogeneous base having 9-membered double ring.
  • Pyrimidine : It is a base that has 6-membered ring.
  • Tissue : Group of cells with similar structure and performing similar function.
  • Tissue culture : Culture of plant in the laboratory from single isolated cells or from a group of cells.
  • Tonoplast : Cell membrane surrounding the vacuole in the cytoplasm of plant cell.
  • Totipotent : cell having ability of a blastomere to develop into various types of cellular structures.
  • Unicellular  (micro-organism) : Comprising of a single cell that carries out all life processes – amoeba.
  • Vacuolar membrane : The membrane surrounding the vacuole.
  • Vacuolation formation of a vacuole.
  • Xanthophore : A yellow chromatophore.
