Match the following (a) Cell Wall (i) Contains organelles (b) Cell Membrane (ii) Contains Chromosomes (c) Cytoplasm (iii) Protects Cell (d) Nucleus (iv) Allows or denies entry of elements Correct Answer (a) - (iii), (b) - (iv), (c) - (i), (d) - (ii)

Concept:

Cell

  • The cell is the basic structure or building block of all living beings. 
  • On basis of a number of cells, organisms are divided into unicellular and multicellular organisms. 
  • Unicellular organisms can perform all kinds of life processes like respiration, digestion of food, reproduction, and excretion of waste.
  • Examples of unicellular organisms include amoeba, bacteria, etc. 
  • Cell have certain components called cell organelles which makes cell to survive. 
  • Some of the cell organelles are vacuole, mitochondria, plastids, etc. 
  • Plant cells and animal cells have certain differences according to their need. 


Explanation:

The cell has different components which collectively perform life processes for the cell. 

  • Cell Membrane: It is a porous structure that allows the entry or exit of materials from the cell according to the requirement. 
  • Nucleus: It contains a central part called nucleolus and chromosomes. Chromosomes carry genes from parents to offspring. 
  • Cytoplasm: It is a jelly-like structure between the nucleus and cell membrane which contains other organelles. 
    • Examples of Such cell organelles are mitochondria, plastids, vacuoles,s etc. 
  • Cell wall: The cell wall is present only in the plant cells. 
    • The basic function of the cell wall is to protect the cell.
    • Plant cells need protection against variations in temperature, high wind speed, atmospheric moisture etc.
