Staining of cell wall of Parenchyma cell
Answers
Answer:
hey here is your answer
Parenchyma consists of relatively large, thin-walled cells. The cells are arranged loosely, that is, there are intercellular spaces among them. The protoplasts of these cells contain chloroplasts. Some of these cells may have amyloplasts and crystals. Pereskia is a member of the cactus family. It has spines but it also has normal leaves. Its flowers are extremely beautiful like those of most cactaceae.
Stain cross sections with Toluidine Blue. What colors are visible in parenchyma cell walls? What does this indicate in terms of cell wall composition?
Young leaf of Elodea.
Mount an entire leaf in a drop of water. Study cells in the region halfway between middle and margin. These leaves are only two cells thick, except at the midrib, and there is little tissue differentiation. This is good material to demonstrate cytoplasmic streaming. The general term Chlorenchyma is used to describe photosynthetic Parenchyma regardless of its location.
Use the condenser iris to observe the cytoplam.
Observe demo with phase contrast optics to study the cytoplasm.
hope it help u
Parenchyma cell walls are usually thin and primary while in sclerenchyma a secondary wall is formed on the inner side of the primary wall. ... Walls of sclerenchyma cells are usually lignified and, therefore, stain red with safranin or phloroglucinol-hydrochloric acid.
