Sara would like to film the movement of chromosomes during cell division Her best choice for a microscope would be a?
light microscope, because the specimen is alive
Why can we just see vacuole nucleus cell membrane and cell wall in onion cell under light microscope and not other organelles?
Onion epidermal cells occur mitosis (nuclear division) and cytokinesis(cell division). Interphase cell typically have one or more number of nuclei, so a few nuclei do not appear next to a cell wall.
What happens during interphase?
the chromosomes are duplicated.
What is the s phase in interphase?
Interphase has three phases: G1--The cell is functioning normally but preparing for cell division so it makes more proteins, organelles and increases the volume of cytoplasm. S-"Synthesis"--The cell duplicates its DNA. G2--The cell continues growing to prepare for cell division.
The relationship of the cell and the microscope?
A cell is a structure which is present inside everything in this world and a microscope is an electronic machine which enables people to see these cells. A cell is classified into plant cell and animal cell and a microscope is classified into electronic microscope and ordinary microscope. Plant cell has cell wall and cell membrane and animal cell has vacuole and nucleus. Electron microscope uses electrons and an ordinary microscope uses simple glass plate. There is also another type of microscope called light microscope which uses light.
Why is cytokinesis seen more readily in light microscope?
It is because cytokinesis is at the beginning of the cell cycle for its division. Cytokinesisis the start of cell division and is thus seen easier and first with a light microscope
Are chromosomes visible in a eukariyotic cell?
Never visible to naked eye.Visible to light microscope during cell division
What feedback does the cell need in order prepare for cell division?
feedback indicates that levels of the molecule are ideal.

Can chromosomes be seen in a cell that is observed in prophase?
Yes. During prophase the chromosomes condense to prepare for cell division.

What event occurs during late interphase in preparation for mitosis?
Gap 2 (G2) - the cell will prepare for cell division during G2 by making the organelles needed for cell division, it will replicate all of the organelles.
How is cell division related to the cell?
If there would not have been any cell division, no life would have exists as there would not have been any reproduction of cells and the first cell ever would have died leaving no trace at all. Each cell prior to its division has to pass through S, G1 & G2 phases to prepare for its division. The actual message for cell division by mitosis or meiosis is received during its entry to cell cycle.

How are chromosomes arranged from the beginning of cell division?
At the beginning of cell divison, however, the chromosomes condense into compact, visable structures that can be seen through a light microscope.
What happens during interphase?
the chromosomes are duplicated.
