White fish mitosis
Mitosis is the process by which cells divide and replicate their genetic material in order to produce two identical daughter cells. This process occurs in all organisms and is essential for growth, development, and repair. White fish, like all other organisms, undergo mitosis in order to produce new cells and maintain the integrity of their genetic information.
The process of mitosis can be broken down into four main phases: prophase, metaphase, anaphase, and telophase. During prophase, the first phase of mitosis, the nucleolus and nuclear envelope disappear, and the chromatids, which are copies of the chromosomes, become visible.
During metaphase, the second phase of mitosis, the chromatids line up at the center of the cell, forming the metaphase plate. This is done through the action of microtubules, which are long, thin structures that help to organize the chromosomes.
During anaphase, the third phase of mitosis, the chromatids are separated and pulled towards opposite poles of the cell. This is done through the action of the mitotic spindle, a structure made up of microtubules that helps to pull the chromosomes apart.
Finally, during telophase, the fourth and final phase of mitosis, two new nuclei are formed, and a cell plate is formed between them, eventually becoming the cell wall. This marks the end of mitosis, and the cell is now considered two daughter cells.
White fish, like all other organisms, undergo mitosis in order to produce new cells and maintain the integrity of their genetic information. This process is essential for the growth and development of white fish, and it ensures that they are able to maintain their genetic diversity, which is important for their survival in the wild. Understanding the process of mitosis is crucial for scientists and biologists who are studying the growth and development of white fish, as well as other organisms.
Mitosis in Whitefish Onion Roots
Healthy cells die through programmed cell death or apoptosis after a number of generations of cell divisions. Place a fixed and stained microscope slide of whitefish blastula cross-sections under the lens of your microscope. The nuclear membrane surrounding the chromosomes also disappears.

Practice locating each of the stages of mitosis in the following photomicrographs. S phase is when metabolism is shifted towards the replication or synthesis of the genetic material. Label the Interphase diagram: 1. As explained, all living organisms have the need to stay alive and reproduce. Some chemotherapy drugs, including taxanes such as Taxol from the Yew tree and alkaloids from the Vinca plant, interfere with mitosis by binding to microtubules and preventing spindle fibers from separating sister chromatids, thus leading to cell death.

In telophase, the chromosomes arrive at the poles and begin to decondense while the nucleus reforms. They won't let you down, no matter what they're up against. Based on this prediction, how much time do you think cells will spend in interphase as opposed to mitosis? But Home Science Tools' products and service can handle it. Telophase A whitefish blastula cell in telophase + cytokinesis Chromosomes begin to disperse. Write your prediction in your notebook.
Onion Root Tip and Whitefish Blastula
In eukaryotes, all chromosomes must be duplicated prior to mitosis and cytokinesis to ensure each new daughter cell has the full complement of genetic information. Mitosis is a controlled process and loss of control can lead to cancerous cells. During late prophase, the nucleoli disappear and the mitotic spindle apparatus assembles. Anaphase A whitefish blastula cell in anaphase During anaphase the mitotic spindle apparatus pulls the sister chromatids of each chromosome apart by attaching to each centromere and then pull the chromatids to each pole of the cell. And if your science inquiry doesn't go as expected, you can expect our customer service team to help.
Interphase Whitefish Blastula Cell
During S phase, the amount of DNA in the nucleus is doubled and copied exactly in preparation to divide. Certain DNA sequences on the ends of the chromosomes called telomeres become shorter during every mitotic cycle of somatic cells, a regulatory mechanism, that contributes to the number of mitotic cycles. If conditions are favorable, the cell continues on to mitosis. But, the chromatin of the nucleus B appears prominent after staining. Note: There are four major phases of mitosis, plus prometaphase, which is a transition phase between prophase and metaphase.
Stages of Mitosis in the Blastula of a Whitefish
These fibers brace the centriole and spindle apparatus against the cell membrane. Activity 1: Observe the Stages of Mitosis in the Blastula of a Whitefish A fundamental property of somatic nonreproductive or body cells of multicellular organisms is mitosis which basically provides new cells for growth and regeneration or replacement of dying and dead cells of the living body. Each pair of sister chromatids has a protein structure, called a kinetochore, which becomes attached to spindle fibers. Cancer cells are not healthy cells. Step 2: Student-Led Planning: Look at Figure 13.
Many single-celled organisms depend on mitosis as their sole or primary way of asexual reproduction. Human chromosomes on the other hand, are are not clearly visible at higher power magnification. Distinct chromosomes are not visible to the microscope at this time. Use the method shown in Figure 13. Prophase Whitefish blastula cells in early prophase During early prophase, the chromosomes condense, making them distinguishable when using a light microscope.

The checkpoints are prone to DNA damage which can cause a disease like cancer see Figure 13. Whitefish Mitosis Whitefish Mitosis A section of whitefish blastula at 400x Introduction Why are whitefish blastula used to study mitosis? During anaphase, the sister chromatids separate and move to opposite poles of the cell. The chromosomes at this stage are dispersed and not visible using a light microscope. The mitotic spindle will consist of microtubules that extend from pole to pole. G2 Phase The cell prepares the enzymes and machinery for mitosis.

Interphase Whitefish blastula cells in interphase The three phases of Interphase G1 Phase Growth: the cell grows in size and carry out their normal day to day activities. METAPHASE Chromosomes which are blue lines under the microscope, are brought to the center by barely visible lines called spindle fibers. Step 5: Critical Analysis: Are the predictions you made supported by your data observations and calculations? Prophase Whitefish Blastula Cell Cell Division - Mitosis - in Whitefish Blastula Cells The arrows A in the photo point to a cell in the prophase stage of mitosis. S Phase Prior to mitosis, the cell readies itself by duplicating its chromosomes and other cellular contents. V-shaped lines of blue are pulled to each end.
