Essay On Animal Cells - Words | Help Me
Though this may just seem as a cell simply dividing, the process of mitosis is extremely complex and vital to cell health and function. When cells mature during interphase, its surface area decreases, making the cell increasingly ineffective the more it grows. If a cell animal cell essay too small of a surface area, animal cell essay, not enough nutrients will be able to cross the membrane to accommodate the cell, animal cell essay, hence not surviving.
Also, during interphase, the many checkpoints put in place assure health and success of mitosis in a eukaryotic cell. These building blocks of our cells get damaged over time, this causes the cells to function less well. The cells in their turn build up the different tissues in the human body, therefor if these cells operate less well the entire human body will be affected by this in the form of aging.
Many research try to find new ways of stopping the aging process. Research discovered that the damage to the molecules which make up out cells is done by highly unstable molecules called reactive oxygen species.
Humans need oxygen to stay alive, as this plays an important role in the energy production of cells. One of the major problems has been getting the gene into the nucleus of the cell and fitting it in its proper place. On top of that problem, animal cell essay, the new gene must function properly like a normal cell would. Many genetic disorders are the effect of a malfunction in a gene. Through gene therapy the malfunctioning gene can be replaced by a working version of the gene that carries out its normal cellular functions.
To make things even more difficult on scientists, fixing the DNA in a few cells will not be beneficial for the patient. Just like the game of rock, animal cell essay, paper, scissors, an organism is much more complex than it seems to be on the surface. There are both plant and animal cells, which are similar, animal cell essay, yet very different. Even further inspection of these organisms uncovers cell organelles, the small structures within the tiny cell that each have their own function and structure.
The five most important organelles in the animal cell are the cytoskeleton, mitochondria, lysosomes, animal cell essay, ribosomes, and nucleus. There are many different types of cells such as human body cells, animal cells and plant cells, each with their own role. In this essay i will be assessing the components of an animal cell and will be evaluating each component in further detail to get a detailed understanding of it all.
The animal cell contains the following components. Animal animal cell essay Nucleus The nucleus is the largest structure in a cell; however some cells may have more than one nucleus such as red blood cell whilst cells such as bacteria cells animal cell essay no nucleus. The nucleus being one of the most important parts of a cell is found in the middle of the cell containing DNA; the DNA is like the control room of each animal cell essay, giving orders to the cell; telling the cell to grow, die etc.
Cell organelles Cells are incredibly complex and most complex cell would be a eukaryotic cell. It has many different organelles and each hold a specific job. Nucleus is very large and is controlling the whole system of the cell. The nucleus contains DNA in the form of chromosomes and is the site of synthesis of RNA.
It is separated from the rest of the cell by a double membrane envelopwhich has pores to allow the movement of substances in or out. Mitochondria are sub-cellular organelles which are found suspended in the cytoplasm of majority of eukaryotic cells. One of their functions is to produce energy in a form ATP that is useful for all cells to maintain the intra and extra cellular functioning.
Mitochondrion has a matrix that is surrounded by two membranes called the inner membrane and the outer membrane. These two membranes are separated by an inter membrane space. The outer membrane has proteins embedded in them most of which are porins- proteins that allow free transfer of molecules such as nutrients, ions, proteins etc.
The nucleus is an organelle found in a eukaryotic cell that is highly specialized; which means it is meant to perform a specific set of actions. It is the administrative center of the cell and also animal cell essay to process information. Within the nucleus is a nucleic acid. Nucleic acid is an acid that helps direct the activities that take place in a cell. Although plant and animal cell essay cells have a lot of differences, they also have their fair share of similarities.
For instance, an animal cell has a centrosome, but so does a plant cell. An average animal cell is made up of centrioles, cytoplasm, endoplasmic reticulum smooth ER and rough ERgolgi animal cell essay, lyosomes, microtubules, mitochondria, nucleus, nucleolus, necleaopore, and ribosomes. Centrioles in an animal cell are made to organize microtubules during mitosis cell division stage.
Cytoplasm helps move stuff around in the cell and also dissolves cellular waste. The transcription phase of protein synthesis takes places in the cell nucleus, animal cell essay. After this step is complete, the mRNA leaves the nucleus and travels to the cell's ribosomes, where translation occurs.
Another important cellular organelle is the mitochondrion. Mitochondria many mitochondrion are often referred to as the power plants of the cell because many of the reactions that produce energy take place in mitochondria. Also important in the life of a cell are the Lysosome. Home Page Essay On Animal Cells, animal cell essay. Essay On Animal Cells Good Essays.
Open Document. Essay Sample Check Writing Quality. Animal animal cell essay are animal cell essay cells, a more complex cell that possess a nucleus that contains all genetic information DNA. In addition to the nucleus, animal cells contain many other tiny cellular structures that perform specific functions called organelles. Furthermore, each organelle has its animal cell essay membrane, composed of a lipid and protein mixture that suits its function As mentioned before, the eukaryotic cells contain a nucleus, the animal cell essay important organelle in a cell.
Therefore, animal cell essay an organelle has a malfunction, the cell will no longer be able to perform its tasks to the fullest, animal cell essay. During the mitochondrial production of energy ATPfive protein complexes drive through and obtain the needed amount of ATP through a transfer of electrons. Get Access. Good Essays.

An animal cell has many contents and that’s why it’s very complex and important. The animal cell contents are cell membrane, Lysosome, nucleus, nucleolus, nuclear membrane, vacuole, mitochondria, centrosome, cytoplasm, rough er, smooth er, ribosome, and Golgi body. The cell membrane is a thin layer of protein and fat that surrounds the cell. This is also called the Aug 17, · Essay on the Functions of Cell Parts. Essay # 1.
