Observing mitosis and meiosis on cell

Finally, it is predicted that the cells will not look large or clear, but it will still be able to give me a general idea of what is going on. The stage that the cell is currently in is anaphase. Discussion If a mother cell has 10 chromosomes, each daughter cell will also have 10 chromosomes.

This was also viewed at X magnification. There are four phases of mitosis: When observing the whitefish embryo cells for the stage of metaphase, the cells took on a circular shape and, like the onion root cell, many nuclei can be seen.

When observing the whitefish embryo cells for the stage of telophase, the overall shape stayed the same except for one cell which is currently in the telophase stage. Prior to mitosis is interphase when the cell grows and duplicates all organellesand post-mitosis is cytokenesis when the cell membrane pinches together to split the actual cell in half to form two cells animal or when a cell plate is formed to separate the cells plant.

This was all seen in X total magnification. Cells divide to replace old, dead cells, to grow and to reproduce new organisms. Hypothesis It can be predicted that all somatic cells will undergo all the stages of mitosis multiple times in their lifetime, that the viewed will be able to see the chromosomes at one stage of mitosis.

Onion Root Cell Cycle Lab Answers

Also, the cell walls in the onion root were barely visible, but the nuclei were very clear. That certain cell is in the metaphase stage. This was, like the onion root cells, viewed at X total magnification.

In this stage the chromosomes reached the centrioles and a nuclear membrane begins to form around each nucleus. In a certain cell, the chromosomes condensed chromatinthat were lined up in the previous stage, break apart from their duplicates and head towards opposite centrioles. The stage that the cell is currently in is prophase.

Materials The materials that were used in this lab are: Mitosis is the division of the nucleus to form two genetically identical nuclei.

LabBench Activity

Like the last two specimen, this was viewed in X magnification. The mother cell duplicates its chromosomes so that each daughter cell will receive the exact number that they originally have.

Microscope with 40X, X and X magnifications Prepared microscope slide of an onion root tip Prepared microscope slide of a whitefish embryo Observations When observing the onion root tip cells for the stage of prophase, the cells took on a brick-like structure and within the cells, small dots the nuclei can be seen.

The cell that is in the telophase stage looks like two circular cells joined together. When observing the whitefish embryo for the stage of anaphase, the overall cell shape stayed the same and they still had a circular shape. In a certain cell, the chromatin, that was condensing during prophase, line up at the equatorial plate.Therefore, observing mitosis in plant cell is much better and easier.

In higher plants the process of forming new cells is restricted to special growth regions called meristems.

These regions usually occur at the tips of stems (shoot) or roots. LabBench Activity Observing Mitosis in a Living Cell.

The cell cycle is something like a dance routine or football play — it is a process that runs continuously, but it.

Cell division may happen by either mitosis or meiosis, depending on what type of cell is invovled. Mitosis is a process by which a cell divides to form two daughter cells. They each have the same exact number and kind of chromosomes as the parent cell.

Use pop bead models of chromosomes to model the cell cycle, mitosis, and meiosis. Observe prepared slides of onion cells and whitefish blastula with a compound microscope to study mitosis and cytokinesis in plant and animal cells.

Basically, mitosis is the process where an eukaryotic cell separates the chromosome in its cell nucleus into two identical sets in two separate nuclei which is known as two identical daughter cells. Mitosis doubles the number of cells without changing the genetic content.5/5(6). Published: Mon, 5 Dec Aim: To observe the stages of the cell cycle in living tissue, generally and specifically in the meristematic cells of the root of garlic and hence consider the duration of the stages of mitosis in relation to the whole cell cycle.
