Cell Biology Quiz-03

Dear Readers,

NEET is the most famous and important medical entrance examination held in our country. This exam is an objective type, an offline test which includes 4 sections namely– Physics, Chemistry, Botany, and Zoology. The maximum marks that can be scored are 720 marks and have 180 questions. About half of the paper consists of questions from Biology, as the NEET exam essentially focuses on capacitating students to go for seats in medical courses. One of the most significant and crucial sections in the NEET exam is of Biology. It comprises of theories, descriptions, discoveries, diagrams, definitions, explanations of differences, and relations. The majority of the topics covered in the NEET syllabus are from the NCERT syllabus of Class 11 & 12 and other related sources become part of the rest of the syllabus. Clear Exam curates a list of articles selected by professionals who recommend the highly vital topics for NEET exams. The table below takes you directly to the respective topic where the in-depth article and the MCQs are available for an easy and productive learning experience. Prior to solving NEET question papers or practicing mock tests, you must ensure to study the basic concepts in NEET and practice a few sample questions related to this exam. Students will be covered for all their studies as the topics are available from basics to even the most advanced. .

Q1.   Nucleic acid occurs in
  •  Golgi body
  •  Lysosomes
  •  Cytoplasm
  •  Mitochondria and chloroplast
(d) Nucleic acids are the polynucleotides composed of carbon, hydrogen, oxygen, nitrogen and phosphorus. They control the basic functions of the cell. On the basis of nucleotides these are of two types – DNA (Deoxyribonucleic Acid) and RNA (Ribonucleic Acid). These are found in all living cells and viruses as genetic material. These are also found in autonomous organelles like mitochondria and chloroplast.

Q2.   Rough endoplasmic reticulum differs from smooth walled endoplasmic reticulum due to the presence of:
  •  DNA
  •  Nucleus
  •  Ribosomes
  •  Ergastic substance
(c) Rough Endoplasmic Reticulum (RER) differs from Smooth Endoplasmic Reticulum (SER) due to presence of ribosomes. Some other difference are as follows: 

Q3.   Plasma membrane is made up of:
  •  Lipid, protein and water
  •  Lipid, protein and manganese
  •  Lipid and carbohydrate
  •  Lipid, protein and carbohydrates
(d) Every living cell is externally covered by a thin transparent, electron microscopic, elastic semipermeable membrane called cell membrane. It is composed of lipids (mostly phospholipid), proteins (peripheral and integral) and carbohydrates (glycoprotein and glycolipids)
Q4.   Which of the following cellular organelles is/are bound by a single membrane? Peroxisomes, lysosomes, mitochondria
  •  Only peroxisomes but not lysosomes and mitochondria
  •  Both peroxisomes and lysosomes but not mitochondria
  •  All of the three organelles
  •  None of the three organelles
(b) The lysosomes are bound by a single unit membrane of 75Å. The peroxisomes are also surrounded by a single unit membrane of about 60Å thickness. The mitochondria is surrounded by double layered membrane.

Q5.   A nucleoside is
  •  Purine/pyrimidine+phosphate
  •  Purine/pyrimidine+sugar
  •  Pyrimidine+purine+phosphate
  •  Purine+sugar+phosphate
  (b) A combination of nitrogen base (purine/pyrimidine) with a pentose sugar (deoxyribose/ribose) in known as nucleoside.

Q6.   Select the right option which relates to Schwann regarding the following statement
I. He reported that cells have a thin outer layer which is today known as plasma membrane
II. Cell wall is a unique character of the plant cell
III. Body of plants and animals are composed of cells and product of cells
Choose the correct option from below
  •  All are incorrect
  •  Only III is correct
  •  All are correct
  •  II and III are correct
(c) Schwan (1839), a British Zoologist, studies different types of animal cells and reported that cells had a thin outer layer. Which is today known as the ‘plasma membrane’. Based on his studies on plant tissues, he also concluded that the presence of a cell wall is a unique character of the plant cells. On the basis of this, Schwann proposed the hypothesis that the bodies of animals and plants are composed of cells and its products. Schleiden and Schwann together formulated the cell theory. This theory however, did not explain as to how new cells were formed. Rudolf Virchow (1855) first explained that cells gets divided and new cells are formed from pre-existing cells (Omnis cellula-e-cellula). He modified the hypothesis of Schleiden and Schwann to give the cell theory a final shape. Cell theory as understood today is (i) All living organism are composed of cells and products of cells (ii) All cells arise from pre-existing cells

Q7.   The mineral present in cell wall is:
  •  Na
  •  Ca
  •  K
  •  Mn
(b) Plant cell wall is mainly composed of cellulose. Other ingredients lignin, cutin, suberin, silica, minerals (e.g., iron, calcium, carbonate) waxes, tannins, resins, gum, etc.

Q8.   A biomembrane consists of lipids, proteins carbohydrates and water. These lipid molecules are:
  •  Amphiatic
  •  Amphipathic
  •  Both polar hydrophilic and non-polar hydrophobic ends
  •  All of the above
(d) A biomembrane consist of lipids (20-79%) proteins (20-70%), carbohydrates (1-5%) and water (20%) The lipid molecules are amphiatic or amphipathic, that is, they possess both polar hydrophilic (water loving) and non-polar hydrophobic (water repelling) ends

Q9.   According to widely accepted ‘fluid mosaic model’ cell membranes are semi-fluid, where lipids and integral proteins can diffuse randomly. In recent years, this model has been modified in several respects. In this regard, which of the following statement is incorrect?
  •  Proteins in cell membranes can travel within the lipid bilayer
  •  Proteins can remain confined within certain domains of the membrane
  •  Proteins can also undergo flip-flip movements in the lipid bilayer
  •  Many proteins remain completely embedded within the lipid bilayer
(c) According to fluid mosaic model, proteins cannot undergo flip-flop movements in the lipid bilayer.

Q10.   Single stranded DNA is found in:
  •  Polio viruses
  •  Rich dwarf virus
  •  TMV
  •  ϕ ×174
(d) Single stranded DNA virus: Bacteriophage ϕ×174, coliphage S 13, bacteriophage M13.
