Cells Make Up Every Living Thing - 1695 Words

Cells make up every living thing. They are mandatory to life and its functions. The cell allows us to do our functions, while doing its own (Cobb, ed., 2009). Inside cells, there are organelles that carry out functions for the cell to live. They have many different kinds of organelles, such as the golgi body, endoplasmic reticulum, and the nucleus (Cellular Transport, 2009). They all have different jobs to allow the cell to function, but the cell membrane has a job that that is done in various different ways. Cell membranes are critical to transporting particles for organelles of the cell. The cell membrane is the exterior layer of the mammalian cell and one of the plant’s outer layers, is a phospholipid bilayer that keeps†¦show more content†¦It goes from high to low. Passive transport requires no energy to do it. Some particles, such as carbon and water, can pass through with no effort on the cell’s part. There are three types of passive transport, such as facilitated diffusion, diffusion, and osmosis. Diffusion has to do with going with the concentration gradient. Facilitated diffusion is diffusion using a protein to help. Osmosis involves water and a selectively permeable membrane. Water is diffused in and out the membrane (Liu, Amagai, Chelen, n.d.). Diffusion is the process of molecules moving from an area of high concentration of the kind of molecule to one of a low concentration (Liu, Amagai, Chelen, n.d.). They are trying to achieve dynamic equilibrium. Dynamic equilibrium is when the concentration outside and inside are equal to one another. An example of diffusion is when someone sprays perfume on in a corner. The perfume will travel to every corner of the room until it is spread evenly across it. Diffusion’s purpose is to have a particle be spread evenly by moving to a high to low concentration (Liu, Amagai, Chelen, n.d.). Facilitated diffusion is diffusion, but has protein to help larger molecules move through the membrane. While it may seem to use energy due to it using a protein, it actually doesn’t require energy. The large particles are going to a lower concentration than what is on the other side of the cell (Cellular Transport, 2009).

The cell is the basic structural, functional, and biological unit of all known living things. They are the smallest unit of life that can be reproduce independently. The material dedicated to stu dy the characteristics and functions of cells is called cell biology. There is a statement which says that from one cell the many, from many cells the individual. In this essay we will mention some characteristics of the cells, and the concepts ofRead MoreYesitS Actually Not All That Easy To Answer That Simple902 Words   |  4 PagesCalculating the number of cells in the human body is tricky.Everyone’s body is made of the same basic stuff. All living things, large or small, plant or animal, are made up of cells. Most living things are made up of one cell and they are called unicellular organisms. Many other living things are made up of a large number of cells that form a larger plant or animal. These living things are known as multicellular organisms. Water makes up about two thirds of the weight of cells.

This cell will react to different sounds or movement. The researchers found that on monkeys when they heard or saw a certain kind of movement that would make a sound or gesture. Also, that found reactions happen within Humans, also. Dr. Rizzolattis said it took them several yearsRead MoreThe Process Of Mitosis And The Function Of Chromosomes, Genes, And Dna1359 Words   |  6 Pagesperformed millions of times a day by every living thing. Each of these cells contains the blueprints of our bodies, which are scientifically known as chromosomes, genes, and DNA. The purpose of this paper is to inform people about the process of mitosis, and to teach people about the function of chromosomes, genes and DNA, and the relation between one another. The process of mitosis is a five step process that starts from just a single cell. Every minute of everyday, cells are dying, and in order for usRead MoreLna Essay1167 Words   |  5 Pagesdid replicators lead to the first cell though? If replicators are meant to replicate and reproduce how did they end up making a living organism? The first cell is presumed to have arisen by the enclosure of self-replicating RNA in a membrane composed of phospholipids which are the principal components of cell membranes. The process of replication lead to the first cell which is called LUCA (Last Universal Common Ancestor). Many scientist believe that all living things on earth originated from an ancientRead MoreLna Essay1166 Words   |  5 Pagesdid replicators lead to the first cell though?

Modern medicine arguably emerged. Both normal and abnormal functions (physiology and pathology) were increasingly understood within smaller units, first the tissues and then the cells. Microscopy also played a key role in the development of bacteriology. Physicians started to use stethoscope as an aid in diagnosing certain diseases and conditions. New ways of diagnosing disease were developed, and surgery emerged as an importantRead MoreThe Immortal Life Of Henrietta Lacks1480 Words   |  6 PagesLacks† brings up a problem in society that was a serious obstacle in the field of medicine in the 1950 ’s. This problem is that the individual rights of a human versus the general need of humanity. The general need of humanity is much more important than the rights of a human. In the 1950’s there was a woman named Henrietta Lacks who had a condition of cervical cancer. She went to the doctors and one of them took her cells without her consent. The scientist started to do test on her cells that theyRead MoreBiology : The Scientific Study Of Life1617 Words   |  7 Pagesto perform actions that living things do. There are seven main properties associated with life, we refer to these as; The Properties of Life. Order, regulation, growth and development, energy processing, response to the environment, reproduction, and evolution; these properties are the basis in which we use to determine whether or not something is â€Å"alive† or â€Å"living.† Cells are the composition of all life. Every living thing on our planet is made up of thousands of cells. Within the properties of
