In order to keep living organisms healthy cells have to go through many stages to replace damaged or worn out cells. One of the necessary steps is mitosis. Mitosis is the process of the body cell and nuclei dividing. This division is the cause of bodies growing and cells repairing. This division is a continuous process which there is four major steps; prophase, metaphase, anaphase, and telophase. Mitosis is comprised of prophase, metaphase, anaphase, and telophase. In prophase chromosomes…

1) Centrioles are a paired feature of animal mitotic spindles that protrude away from the centrisome of cells and are primarily tasked with the creation of microtubules. The microtubules give way to mitotic spindles, which play a vital role in both mitosis and cytokinesis as they give cilia and flagellum the ability to generate motion and they ensure both newly formed cells contain paired centrioles during the later stages of cell division. Kinetochores are protein structures that produce…

Mitosis is used for all of your body’s cell division. It adds new cells during development and replaces old and worn-out cells throughout your life. Mitosis’ goal is to produce daughter cells that are genetically identical to their mothers and have two sets of chromosomes. Mitosis produces 2 diploid cells. Both mitosis and meiosis are processes of cell division. They have the same steps for cell division, prophase, metaphase, anaphase, and telophase. The stages of which are interphase, prophase…

Myosin are a large superfamily of motor molecule which is move along cytoskeletal filaments and interact with actin filaments. That movement requires huge amount of hydrolysis ATP molecules to change the conformation. The genomic analysis thirteen different members of the myosin gene. In addition, the most present myosin type in all eukaryotic cells are: myosin I and myosin II. On the other hand, the less present type of myosin is myosin V. Also, myosin can be divided to two class; conventional…

Paramecium is part of the Alveolata clade, which are heterotrophs and a major clade that belogs to the kingdom Protista. Paramecium are single-celled organisms with an oval, slipper shaped. On the outside of the Paramecium you can find the radiatin canal and a contractile vacuole. The cytoplasm, food vacuoles, the macronucleus, and the micronucleus are located inside. Another characteristic of them is that they move faster than other protists. They live in aquatic environments, but most usual in…

What is yeast? To most people yeast is just something that is in the food that we eat; However to the scientific community yeast is much more than that. According to the Dictionary of Student Science yeast is a one-celled fungi that can cause the fermentation of carbohydrates, producing carbon dioxide and alcohol. ( ) Yeast can be found in the soil, water, on the surface of plants as well as on the skin of humans. Like other fungi, yeasts gets its food from the organic matter around them. The…

The ways in which cells interact with each other is very similar to many concepts used in the real world due to the interactions between the cells and the techniques used for cell growth. A multitude of the techniques used by the cells in the biological market, during the process of trading metabolic products between bacteria, are almost identical to techniques used by countries, firms, and people in the economic market. Through the trade of metabolic products the cells are functioning as a…

The purpose of this report is to investigate the following observations; Euglena is a unicellular organism in the kingdom of Protista, the cells are both autotrophic and heterotrophic which means if there is no food source but there is a light source they will fall on their autotroph tendencies through photosynthesis while if there is a food source but no true light source they will fall on their heterotroph tendencies. Euglenas show positive photo-taxis due to their ability to preform…

Nucleus: The nucleus is the control centre of the cell. It’s much like a blueprint that contains all of the instructions on building the body. It contains genetic material called DNA. This DNA has instructions for building proteins and is essential to cell reproduction. If a cell doesn’t have a nucleus for whatever reason will certainly die. The nucleus conforms to the shape of the cell so it could be oval or it could be spherical. The nucleus has three recognizable regions; the nuclear…

Macromolecules are of great interest to the study of anatomy and physiology due to the fact that they carry out most functions of a cell providing it with life. They provides structural support, a source of stored fuel, the ability to store and retrieve genetic information, and ability to speed biochemical reactions (Prakash, 2008). There are four main types of macromolecules including proteins, carbohydrates, nucleic acid and lipids. This essay is specifically on the study of carboyhdrates as…
