A typical feature of a plant cell is the presence of

  • A) chromosome in nucleus
  • B) cellulose cell wall
  • C) mitochondria
  • D) membrane around the nucleus

Correct Answer: B) cellulose cell wall

Explanation

Plant cells have unique features that distinguish them from animal cells. One of the most prominent features of plant cells is the presence of a cell wall made up of cellulose. This feature gives the cell its shape and provides support to the plant. It also protects the cell from external damage and regulates the movement of molecules in and out of the cell. Option A is incorrect because both plant and animal cells have chromosomes in the nucleus. Chromosomes contain the genetic material of the cell. Option C is also incorrect because plant cells contain mitochondria, which are organelles responsible for producing energy for the cell. Option D is incorrect because only eukaryotic cells, which include both plant and animal cells, have a membrane around the nucleus. This membrane is called the nuclear envelope and it separates the nucleus from the rest of the cell. Therefore, the correct answer is Option B, cellulose cell wall, which is a unique feature of plant cells. It gives the cell its shape, provides support and protection, and regulates the movement of molecules in and out of the cell.
