Define cell wall in 5 points |
|
Answer» # A CELL wall is a structural layer surrounding some types of cells, just outside the cell MEMBRANE. # It can be tough, flexible, and sometimes rigid. #It provides the cell with both structural support and protection, and also acts as a filtering mechanism.# Cell walls are present in most prokaryotes (EXCEPT mollicute BACTERIA), in algae, fungi and EUKARYOTES including plants but are absent in animals. #A major function is to act as pressure vessels, preventing over-expansion of the cell when water enters. |
