  • Question 1
    1 / -0
    An organism in which all the activities are performed by a single cell is called:
    Solution
    An organism that performs and exhibits all functions of life via a single cell, it is a unicellular organism. Such as prokaryotes like bacteria, eukaryotes like yeast are unicellular organisms. They lack a group of cells (tissue) or organ systems to perform specific functions. All the cellular functions for it to be living are performed by the individual cell.  So, the correct answer is 'Unicellular'.
  • Question 2
    1 / -0
    The largest cell measuring 170 mm × 150 mm is the egg of ___________.
    Solution
    The egg of an ostrich is the largest cell, with dimensions of 170 mm $$\times$$ 150 mm and weighs about 1.3 kgs. It has a cell volume of about 1.1 $$\times$$ 10$$^{15}$$ $$\mu$$m$$^3$$.
    So, the correct answer is option C.
  • Question 3
    1 / -0
    Each organ is further made up of smaller parts called __________.
    Solution
    • Each organ is further made up of smaller parts called tissues. A tissue is a group of similar cells performing a specific function.
    • Cells are the basic building blocks of living things. 
    • Pseudopodia is a retractile process of the cytoplasm of a cell that functions especially as an organ of locomotion and food-acquiring.
    So, the correct option is A.
  • Question 4
    1 / -0
    Cells are said to contain
    Solution
    • The cell is considered to be the basic unit of life in many pathological processes. 
    • In addition, the phenomenon of energy flow occurs in cells in processes that are part of the function known as metabolism. 
    • Cells contain hereditary information (DNA), which is passed from cell to cell during cell division and from one generation to next. Thus, the correct answer is option D
  • Question 5
    1 / -0
    A nervous system is comprised of ________ cells.
    Solution
    The nervous system is comprised of nerve cells which help in control and coordination in the body.
    The correct option is D.
  • Question 6
    1 / -0
    Which of the following are amoeboid in shape?
  • Question 7
    1 / -0
    Cell wall of plant cell is mainly made up of_________.
    Solution
    The cell wall is only present in a plant cell, which gives a definite shape and structure to the plant cell. The cell wall of the plant is mainly made up of cellulose. It is a non-living part of the plant cell.
    So, the correct answer is option A. 
  • Question 8
    1 / -0
    How are plant cells different from animal cells?
    Solution
    • Plant cells have cell wall, plastids, and a large central vacuole, which are not found in animal cells. The cell wall is a rigid covering that protects the cell, provides structural support and gives shape to the cell. 
    • The chloroplasts, found in plant cells, contain a green pigment called as chlorophyll, which captures the light energy that drives the reactions of plant photosynthesis. 

    Thus, the correct answer is option C.
  • Question 9
    1 / -0
    Name the cell organelle which is called the 'Control room of the cell':
    Solution
    The nucleus, in addition to its role in inheritance, acts as the regulator of the activities of the cell. Hence, it is the control room of the cell.
    So, the correct answer is option A.
  • Question 10
    1 / -0
    Which cell organelle controls most of the activities of the cell?
    Solution
    Correct option: B
    Explanation: 
    • The nucleus is one of the most important organelles and the storehouse of the genetic material of the cell.
    • It controls many important regulatory functions such as replication, transcription, and all other activities of the cells.
    • The endoplasmic reticulum can be smooth or rough depending on the presence/absence of ribosomes.
    • The RER is involved in protein synthesis and SER in lipid synthesis.
    • Mitochondria is essential as it produces the energy required for the cell.
    • The Golgi body has functions such as packaging and transportation of molecules.
    Hence, the cell organelle that controls most of the activities of the cell is the "nucleus".
