Correct Answer - Option 4 : Cell wall

The correct answer is Cell wall.

  • The nonliving part of a tomato cell is its cell wall because the cell wall mainly constitutes nonliving cellulose.
  • The cell wall forms the outer covering for the cell membrane of Bacteria, Fungi, Algae, and Plants.
  • It gives the cell a definite shape.
  • The plant cell wall is made up of cellulose and pectin.
  • The cell wall also acts as the first line of defence against pathogens.
  • The Chloroplast is a double membrane-bound cell organelle.
  • Out of the two membranes, the inner membrane is relatively less permeable. (the outer membrane contains porins).
  • The space limited by the inner membrane is called the stroma.
  • The Nucleus is a double membrane-bound dense protoplasmic body, which controls all the cellular metabolism and encloses the genetic information of the cell.
  • It is considered the controller or director of the cell.
  • The Cell membrane is the selectively permeable living boundary of the cell.
  • It is also called Biomembrane or Plasma membrane.
