Anaphase occurs next in which the cell’s centromeres divide and the sister chromatids separate and move to the opposite sides of the cell. Then comes telophase in which the nuclear membrane begins to reform and the chromosome begin to decondense. Also the spindle fibers disappear. We end this
Unlike archaea and bacteria eukarya is the type of cell with a nucleus.
n Earth Research and describe how technological advances have increased knowledge of the variety of prokaryotic organisms. Over the course of time, there have been a variety of technological advances which have shed light on the existing variety of prokaryotic organisms. Microscopes have given us the opportunity to observe structures that are of a smaller scale, such as prokaryotes, which are small as well as unicellular. The advancement of microscope technology saw the development of electron microscopes: they allow us to observe the internal structures of prokaryotic cells.
Prokaryotes and Eukaryotes each express their gene regulation in differently. The structure of the the cells are not the same so the genes expression are not the same. Prokaryotes and Eukaryotes have things that are the same in their process of gene expression. Since prokaryote cell’s do not have a nucleus, gene expression happen in the cytoplasm for them. Prokaryotes genes are transcribed on the lac operon.
Cells go through a process called mitosis in order to divide and produce more cells. When cells go through mitosis, the DNA replicates and the cell divides in two separate daughter cells. The cells will go through five stages when they divide; interphase, prophase, metaphase, anaphase and telophase. The regulation of cell growth is not constant and is determined by feedback from the cell. Cells may reproduce because of cell growth, cell replacement or regeneration.
All eukaryotic cells are membrane-bound, containing cell organelles which are there for specific functions. The main two types of eukaryotic cell are animal and plant cells, which have some similar but some different cell organelles as they are needed for a range of different functions. They both share the organelles, the nucleus, plasma membrane, nucleolus, endoplasmic reticulum (rough and smooth), golgi body, lysosomes, mitochondria, ribosomes and cytoplasm. However plant eukaryotic cells contain chloroplasts and have a cell wall which animal cells don’t.
The idea of cell division, mitosis and binary fission, are ideas that make me stop and think. Mitosis is a type of cell division that happens in cells with a nucleus, and ends in two identical daughter cells. Mitosis interests me because of how complex the process is. It is amazing how it goes through various stages without hardly ever a mistake, and ends with two identical daughter cells. Binary Fission is a type of cell division that happens in cells without a nucleus, and also ends with two identical cells.
Prokarytoic cells lack endoplasmic reticulum were eukaryotic cells have it present. There is also be big difference in size as well Eukarytoic cells are around 10-100um as compared to the small prokaryotic cells are just around
Referring back to the genetic code, even though prokaryotes and eukaryotes share the same genetic code, the genome possessed by eukaryotes is far more extensive and complicated than that of prokaryotes. Some mechanisms also contribute to a difference in the genetic model; focussing on the process of transcription - prokaryotes have a simpler method and they only utilize a single type of RNA polymerase, whereas in Eukaryotic cells there are three different types of RNA polymerases (pol I, pol II, pol III) specific to each group of RNA.This also plays a part in the far more complex nature and structure of eukaryotic cells. Extending on genetic differences, it is essential to make note of the difference in DNA structure. Differences are also evident in chromosomal structure, prokaryotes tend to have a simpler structure of a single loop of chromosome often referred to as the plasmid. Where as chromosomes in eukaryotes have a more linear shape and are arranged in multiples.
3. GROWTH AND CELL DIVISION OF PHYTOPLANKTON Phytoplanktons have diversity and are of both the types prokaryotic and eukaryotic. Cell division is the vital process for regeneration. Prokaryotic forms of phytoplankton which comes under domain bacteria divide by basic process of cell division like binary fission. Eukaryotic phytolanktons which comes under domain eukarya are divide by the process of mitosis.
There are three type of cell division: binary fission, mitosis and meiosis ("Binary Fission”, "Cell Division, Mitosis, and Meiosis"). Binary fission occurs in prokaryotic cells, such as bacteria, in this process the cell copies all of its DNA and then segregates the copies into opposite ends of the cell before splitting into two new cells (“Binary Fission”). An advantage of binary fission is that it is easy to create new cells quickly and in large quantities (“Asexual Reproduction”). A drawback of binary fission is that if something goes wrong such as a virus or a fatal mutation then the entire population of the cells can be destroyed due to a lack of genetic diversity (“Asexual Reproduction”). Mitosis is a type of cell division that occurs in both plants and animal cells ("Cell Division, Mitosis, and Meiosis.").
As we known that the cell represents the structural and functional unit in living organisms, human health of the health of its cells and that any defect in the work of the cell, if not cured by the body, lead to the occurrence of diseases may be deadly, such as cancer. To ensure this consistency, the cell contains a set of components that work in an orderly manner that allows the production of material necessary for cell survival and repair any errors . The Living organisms are classified according to their cell components into two large families: Prokaryote, organisms that are in the cell with a single cell and are simple in composition. The second type is eukaryote, organisms with more complex cells.
The first cell division, meiosis I, the cell separates the homologous chromosomes. Which in order for the chromosomes to be homologous it has to have the same location of the centromere, gene, and length size of the chromosome. Meiosis I goes through four stages, prophase I, metaphase I, anaphase I, and telophase I, as well as cytokinesis in telophase. In prophase I, the chromosomes shorten, the nuclear envelope, and the nucleolus disappears.
Bacterial growth is the asexual reproduction, or cell division, of a bacterium into two daughter cells, in a process called binary fission. Providing no mutational event occurs the resulting daughter cells are genetically identical to the original cell. Hence, "local doubling" of the bacterial population occurs. Both daughter cells from the division do not necessarily survive. However, if the number surviving exceeds unity on average, the bacterial population undergoes exponential growth.
I enjoyed reading your discussion post you gave good insight on prokaryotes and eukaryotes. Prokaryotic bacteria contains a lot more of biomass with plants along with elements in ecologies. Although some have pathogens, but a lot of prokaryotes are important to for life recurrence. Prokaryotes have metabolic than eukaryotic cells. Prokaryotes contain oxygen to establish organic molecules accessible repairing climatic nitrogen, which can form carbon to build organic molecules.
