Questions and Answers

Which of the following is a structural difference between epidermal and cortical cells?

  • Epidermal cells are rectangular in shape, while cortical cells have no specific shape and are unspecialized parenchyma
  • Epidermal cells have relatively thick walls with cuticle, while cortical cells have thin walls with no thickening of secondary wall (correct)
  • Epidermal cells are mainly storage cells, while cortical cells are mainly protective due to outermost and continuous layer
  • Epidermal cells have many intercellular spaces, while cortical cells have no intercellular spaces
  • Which of the following is a functional difference between epidermal and cortical cells?

  • Epidermal cells offer fair resistance to the movement of water, while cortical cells offer least resistance to the movement of water
  • Epidermal cells absorb water by virtue of root hairs elongated outgrowths, while cortical cells form symplastic connections with them (correct)
  • Epidermal cells are composed of different kinds of cells carrying out different functions, while cortical cells are composed of similar kind of cells mostly performing similar functions
  • Epidermal cells show wall thickening and persist for longer time under stressful conditions, while cortical cells undergo reduction in size under stressful conditions
