Mitosis vs. Meiosis The dividing of cells is an important bodily function for an organism to survive. The way our bodies work is very delicate and precise. Therefore the ways our body has to function to sustain life then must be handled in such ways there are two main ways cells divide in an organism; mitosis and meiosis. And they are similar in the way they divide cells, but they do have their differences First the big main difference between the two is that mitosis is for asexual reproduction and meiosis is used in the preparation for sexual reproduction. Mitosis creates body cells that are used so cells divide for things like growth and renewal of cells that die compared meiosis which makes the egg or sperm sex cell. Second, in mitosis the daughter cells contain diploid or two copies of each chromosome where in meiosis the daughter cells have haploids, which are only one copy of each chromosome. In addition, mitosis is a parental cell that divides once into two daughters cells with identical genetic information as the original compared to meiosis which divide twice resulting in four cells each containing only half the number of chromosomes, but each chromosome contains information from both parents making the cell unique. Lastly during the prophase phase in mitosis chromosomes condense, a spindle begins to form from the centrioles, the centrioles begin tom separate, and the nuclear envelope fragments. In meiosis it is very similar except the chromosomes attach to the membrane of the nucleus and pair up, which is called synapses, and cross over at points causing in the individuality of the daughter cells. Just like their differences, the two forms of cell division do have their similarities. First, both mitosis and meiosis go through the same main phases; interphase, prophase,…
born in 1921, and is primarily a biophysicist (although he is currently a researcher at the Marina Biological Laboratory) and a member of the National Academy of Sciences. His research field is the visualization of dynamic processes within living cells using the light microscope. He has both a Ph. D. and an M.A. in biology from Princeton University. He also has something known as a “Rigakushi”, in zoology from the Tokyo University in 1944.

Exercise 1: Mitosis in Animal and Plant Cells
9. Think back to the pre-lab questions about the differences in plant and animal cell mitosis. Were your predictions correct? What, if any, differences did you actually see?
“If the division of plant and animal cells is observed, the plant cells will not change shape during division while the animal cells will form cleavage, morph and form two rounded cells.” Because this was my prediction, it was correct. The animal cells change…

20 Significant Ideas
1. The process of mitotic cell division has been studied intensely for more than 50 years.
2. Using fluorescence microscopy, today's scientists can see the tug-of-war cells undergo as they move through mitosis.
3. Thread-like proteins, called microtubules, extend…
Both plant and animal cells are eukaryotic cells which mean they have a ‘true’ nucleus. Animal cells can come in an array of sizes and unusual shapes, unlike a plant cell which is typically rectangular or cube shaped.
What can be found in a Plant Cell and an Animal Cell?
Cell Membrane - This surrounds the cytoplasm in the cell, enclosing its contents. It is thin and semi permeable and allows substances to move through it.
Cytoplasm - a gel like substance…

Mitoses are a type of cell division whereby the chromosomes in a cells nucleus are separated into two identical sets of chromosomes each in its own nucleus. Mitoses usually results in two genetically identical daughter cells developing from a single parent cell, and is immediately followed by cytokinesis, which in turn divides the cytoplasm, organelles, cell membrane and karyokinesis. Mitosis is used by unicellular (an organism consisting of only one cell i.e., bacteria) organisms to reproduce;…
A eukaryotic cell, on the road to division, goes through two major stages. These two stages are known as the cell cycle. The first is called interphase where the cell grows and develops before dividing; within this, there are three phases: G1, S, and G2. The next stage is called mitosis where the division of the cell actually occurs. During this duplicating process, two identical cells containing the same number of chromosomes and the same generic information are created. Mitosis is broken down into…
All new cells come from previously existing cells. New cells are formed by the process of cell division, which involves both division of the cell’s nucleus (called mitosis) and division of the cytoplasm (called cytokinesis).
Dividing cells experience both of these events along with a period of time between divisions called interphase. During interphase, the nucleus appears normal and the cell is performing its usual cellular functions. Also, the cell is increasing…
What is the difference between Mitosis and Meiosis?
What is the difference between Mitosis and Meiosis? Mitosis self produces cells asexually in single celled organisms. The counterpart of Mitosis is Meiosis. Meiosis occurs in multi-cellular organisms such as plants and animals. The process involves the use of gametes from two organisms such as the egg and sperm for example. In the process of fusion, the gametes combine two different sets of genetic material into one new…
It is unlikely to find all of the structures within a cell because many of them do not happen all
in one phase. One example is the cleavage furrow. This only happens during telophase. Also,
these images are super small, and thus, may be difficult to located. In Both structures of the
cells, the 2n number is 4.
The purpose of mitosis, otherwise known as Cell or Nuclear division, is cell regeneration,
growth, and asexual reproduction,while the purpose of meiosis is the production of gametes
for sexual reproduction. Mitosis is a sing…
