Introduction

INTRODUCTION
  • Cell wall is present external to the cytoplasmic membrane. It is a rigid structure which gives shape to the cell. It prevents the cell from expanding due to uptake of water, since most bacteria live in hypotonic environments.
  • Cell wall constitutes as much as 10-40% of the dry weight of the cell. It is usually essential for bacterial growth and division.
  • Bacterial cells whose cell walls have been completely removed are incapable of normal growth and division.
