Weekly Quiz Competition
  • Question 1
    1 / -0
    Starch is stored in
    Solution
    • Plastids are a pigment containing double membrane-bound organelle which is the site of manufacture and storage of chemical compounds.
    • Plastids are of three types on the basis of the pigments present within them:-
    • 1. chloroplast (green plastid), 2. The chromoplast (coloured plastid) and 3. Leucoplast (colourless plastid).
    • Leucoplasts differentiate into specialized plastids to store the starch and are called amyloplasts.
    • The glucose which is not used up in the metabolic activities is stored in the stroma of the chloroplast in the form of starch grains.
    • So, the correct answer is 'Both B and C'.
  • Question 2
    1 / -0
    Organelle associated with lipid and lipoprotein synthesis is
    Solution
    • The endoplasmic reticulum (smooth and rough) is an interconnected network of flattened, membrane-enclosed sacs or tube-like structure which are evenly distributed throughout the cytoplasm.
    • A smooth endoplasmic reticulum lacks ribosomes.
    • It helps in the production and metabolism of lipid, it also produces lipoproteins, steroid hormones and helps in detoxification.
    • So, the correct answer is 'E.R'.
  • Question 3
    1 / -0
    Amyloplasts are connected with storage of
    Solution
    • Plastids are a pigment containing double membrane-bound organelle which is the site of manufacture and storage of chemical compounds.
    • Leucoplast is colourless plastid as it contains colourless pigments and granules.
    • Leucoplasts differentiate into specialized plastids to store the starch and are called amyloplasts.
    • So, the correct answer is 'Starch'.
  • Question 4
    1 / -0
    Plastids storing proteins are called
    Solution
    • Plastids are a pigment containing double membrane-bound organelle which is the site of manufacture and storage of chemical compounds.
    • Plastids are of three types on the basis of the pigments present within them:-
    • 1. chloroplast (green plastid), 2. The chromoplast (coloured plastid) and 3. Leucoplast (colourless plastid).
    • Leucoplasts differentiate into specialized plastids to store and modify the proteins and are called proteinoplasts or aleuroplasts,
    • So, the correct answer is 'Aleuroplasts'.
  • Question 5
    1 / -0
    Organelle connected with glycosidation of proteins is __________.
    Solution
    Glycosylation is the attachment of sugar moieties to proteins by glycosidic linkage and occurs in the endoplasmic reticulum. Thus the correct answer is option B.
  • Question 6
    1 / -0
    Ribosomes are granules made of
    Solution
    • Ribosomes are known as protein factories because they are the main site of protein synthesis. 
    • They are composed of ribosomal RNA and proteins.
    • Its main function includes protein synthesis by translating the rRNA for forming specific proteins required for the cell functioning.
    • So, the correct answer is 'rRNA and proteins'.
  • Question 7
    1 / -0
    Ribosome is mainly formed of
    Solution
    • Ribosomes are known as protein factories because they are the main site of protein synthesis. 
    • They are composed of ribonucleic acids and proteins.
    • It is made up of two subunits-
    1. Large subunits- join amino acids to form a polypeptide chain.
    2. Small subunits- reads RNA.
    • Each subunit is made up of one or more of ribosomal RNA and ribosomal proteins.
    • So, the correct answer is 'RNA'.
  • Question 8
    1 / -0
    When a lysosome fuses with a phagosome/food, it results in the formation of
    Solution
    • Lysosomes are membrane-bound organelles which contain acid hydrolases or digestive enzymes that digest excess or worn out organelles, food particles, engulfed viruses or bacteria and macromolecules.
    • Phagosome can be defined as the vesicle which is formed around the material engulfed by a phagocyte through phagocytosis.
    • The fusion of a lysosome with a phagosome gives rise to secondary lysosomes.
    • So, the correct answer is 'Secondary lysosome'.
  • Question 9
    1 / -0
    Which is present nearest to plasma membrane in plant cell?
    Solution
    • The cell wall in plants and few algae consists of three important layers:
    1. The primary cell wall is the outermost thin, flexible and extensible layer.
    2. The secondary cell wall is a thick layer present inside the primary cell wall and is sandwiched between the plasmalemma and primary cell wall.
    3. The middle lamella is the first formed layer which is rich in pectins and forms plasmodesmata connections between adjacent cell walls.
    • So, the correct answer is 'Secondary wall'.
  • Question 10
    1 / -0
    Eukaryotic ribosomes are
    Solution
    • Ribosomes are known as protein factories because they are the main site of protein synthesis. 
    • They are composed of ribonucleic acids and proteins.
    • In eukaryotes, the ribosome is 80S type.
    • The larger subunit is 60S and smaller subunit is 40S.
    • Each subunit is made up one or more of ribosomal RNA molecules and ribosomal proteins.
    • So, the correct answer is '80 S'.
