Plant cells are eukaryotic cells that differ in several key aspects from the cells of other eukaryotic organisms. Their distinctive features include: A large central vacuole‚ a water-filled volume enclosed by a membrane known as the tonoplast maintains the cell’s turgor‚ controls movement of molecules between the cytosol and sap‚ stores useful material and digests waste proteins and organelles. A cell wall composed of cellulose and hemicellulose‚ pectin and in many cases lignin‚ is secreted by

Cell wall is a fairly rigid‚ protective and supportive layer surrounding the cell external to plasma membrane of plants‚ bacteria‚ archaea‚ fungi and algae. It is absent in animals and most protists. It was first observed by Robert Hooke in 1665. It is not an entirely rigid structure as the cell wall expands due to the growth of the cell. It varies in thickness from o.1mm to I0mm.in most of the cells‚ cell wall is present from the very beginning to the last‚ but in slime molds (myxomycetes)

DETERMINATION OF THE WATER POTENTIAL OF POTATO TUBER CELLS. Method. Five sucrose solutions with varying molarity and one control containing distilled water were prepared and poured into test tubes. The potato discs were dried‚ weighed and added to the test tubes. The discs were then weighed again after a period of 24 hours. The percentage change in mass was then calculated.
