Why do plants have a cellwall that we don't have? Collect Chromosome number of any 10 organisms including plants.
Answers
Answer:
ans
Explanation:
The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. ... In drought, a plant may wilt, but its cell walls help maintain the structural integrity of its stems, leaves, and other structures, despite a shrinking, less turgid vacuole.
Answer:
the answer is explained below
Explanation:
Cell wall is present only in plants because plant requires it for protection.
Cell wall provides shape to the cell and protects it from mechanical and osmotic stress. Cell wall is extra additional layer after cell membrane in plant cells and it protects the plant from high temperature,high pressure etc. Cell wall helps in cell to cell interaction through plasmodesmata and it provides barrier to undesirable substance.
