Which of the following is found in plant cells only?

The correct answer is Cell wall.Key Points

• Plant cells have a rigid cell wall made up of cellulose, which provides structural support and protection to the cell.
• The cell membrane is present in both plant and animal cells, and it forms a barrier between the cell and its environment, controlling the movement of substances in and out of the cell.

Additional Information

• Cell membrane:
  • It is a thin, flexible barrier made up of lipids and proteins that surrounds the cell and regulates the movement of materials in and out of the cell.
• Nucleolus:
  • It is a dense, spherical structure found within the nucleus of eukaryotic cells, which is involved in the synthesis of ribosomal RNA and the assembly of ribosomes.
• Mitochondria:
  • These are membrane-bound organelles found in eukaryotic cells, which are responsible for producing energy in the form of ATP through cellular respiration.
  • They contain their own DNA and can replicate independently within the cell.
