Document Summary
To resolve this problem, 5% nacl solution is added to the specimen, which removes the water from the plant, making the cell wall more visible. Elodea plant: what is the name of the organism shown below? cyanobacteria. Fluid endoplasm: label the following parts. plasmalemma. Dna replication occurs during this stage and all you see is the nucleus and heterochromatin: prophase is the stage where the chromosomes shorten and thicken. Also, cytokinesis occurs during this phase where cell walls form around plant cells: mitosis is more easily seen in plants because the chromosomes stand out more clearly, the stain used for chromosomes is called the feulgen stain. The stain colours the dna magenta red: the dna is first hydrolyzed with hot hcl which removes the purine bases and frees the aldehyde groups of the sugar. The resulting product is called apurinic acid aka dna lacking purines.
