Q: Parenchyma and collenchyma are the types of _____tissues.
  • A. Vascular
  • B. Mechanical
  • C. Simple permanent
  • D. Nervous
Correct Answer: Option C - Simple permanent tissues are composed of cells which are structurally and functionally similar. These tissues are made up of one type of cells. A few layers of cells beneath the epidermis are generally simple permanent tissue. Simple tissues are of three types, namely parenchyma, collenchyma and sclerenchyma. Parenchyma – They are living cells, soft in nature due to the presence of thin-walled cells. Collenchyma – These are characterized by uneven thick-walled living cells. Sclerenchyma – They have cells with thickened lignified walls, providing them strength and making them waterproof.
