Prophase During this stage of mitosis, the nucleolus is still visible. However, the nucleus appears grainy due to chromosomal condensation. The following is a diagrammatic representation of an onion root tip cell during prophase:Diagrammatic representation of an onion root tip cell during prophase. ...
A series of electron micrographs has been made of thinly sectioned onion root tip fixed with several types of fixative and embedded in methacrylate. With acid fixation the cellular protoplasm appears shredded at these high magnifications, but after neutral fixation the cellular contents form ...
THIS IS DUE TOMORROW .d o c in .c o m The Assignment In this activity, you will be presented with cells from the tip of an onion root. You will classify each cell based on what phase it is in. At the end you will count up the cells found in each phase and use those numbers ...

Infer why whitefish embryo cells and root-tip cells are used to study mitosis instead of cells in a human bone or plant leaf. What is the function of the cell wall in an onion cell? Why is most of the supportive tissue in plants made up of dead cells? Why do cells in the stratum ...
