Cells are some of the smallest organisms around. All living things consist of cells, and yet they are invisible to the naked eye. Cells are the basic structural and functional units of life. Cells are made up of many different parts which allow them to function properly.

All cells are separated from their surrounding by a cell membrane. The cell membrane regulates what enters and leaves the cell and also aids in the protection and support of the cell. A cell membrane is similar to the walls surrounding your house.

In plants the cell membrane is surrounded by a cell wall. The cell wall is outside the cell membrane, and its purpose is to help the membrane protect and support the cell. Since the cell wall is very porous, water, oxygen, carbon dioxide, and other substances can pass through easily. A cell wall is similar to a fence around your house, because it helps protect other things from getting inside the cell.

In many cells there is a the nucleus, which was first described by Robert Brown. If a cell does or does not have a nucleus has been used by scientists to divide cells into two general categories. The two categories are Eukaryotics, which are cells with a nucleus, and Prokaryotic, which are cells without a nucleus. The nucleus has been found to be the information center of the cell and contains DNA. It also directs all activities that occur in a living cell. It’s like a mini me of the heart and brain of a human body.

Most nuclei contain a small area called the nuc...

    The building of the grocery store is like the cell membrane, because it gives it structure and keeps everything inside safe. The security guard of the front door in the grocery store is like the cell membrane, because it says what can come in and out of the cell. The boss of the store is like the nucleus, because they tell the employes what to do and what needs to be done.

  • The Cell Membrane In A Basketball Stadium Room

    The cell membrane is a structure that controls what enters and leaves the cell. In a basketball stadium, the security guards are like the cell membrane. They can say who comes in if they don’t cause any problems and are following the rules and they can reject them and make them leave if they have something they aren’t supposed to or they are doing something wrong. This is how security guards are like a plant cell’s cell membrane because the security guards control what enters and leaves the stadium like the membrane controls what enters and leaves the cell.

    The body is composed of cells, which form the basic unit of life. Unique cells found in the body are the stem cells. These cells are biological cells that are not specialized for particular functioning in organisms. They can be distinguished since they have the ability to differentiate or divide into multiple body cells, and their ability to replicate self. They are unique in the way they can renew themselves by undergoing cell division when inactive for a long period. It is also possible to induce stem cells to organs or tissue cells under some conditions. When the cells divide, they replenish the cells in a living organism. They serve as an internal system that repairs and replaces the tissues that are worn out.1 Dividing cells may remain as stem cells or become specialized in their functions, for instance red blood cells, brain or muscle cells.

  • Understanding Prokaryotic and Eukaryotic Cells

    There are many different cells that do many different things. But all of these cells fall into two categories: prokaryotic and eukaryotic cells. Eukaryotic cells contain a nucleus and are larger in size than prokaryotic cells. Prokaryotic cells do not contain a nucleus, are smaller and simpler than eukaryotic cells. Two of their similarities are they both have DNA as their genetic material and are covered by a cell membrane.

  • Cell Cycle Essay

    Eukaryotic cells have their chromosomes contained in a nucleus. Unicellular orgasisms such as amoebas and yeast, or multi-cellular organisms such as plants and animals consist of eukaryotic cells. Human being consist of approximately 1 billion cells per gram tissue. DNA located in 23 pairs of chromosomes is contained in each cell nucleus. Schleiden in 1838 and Schwann in 1839 made very important discoveries that we consist of cells, and Remark discovered that cells prolifarate through division in 1850. Three decades ago, the molecular mechanisms that regulate the cell cycle and thus cell division was able to be identified. It has been known that these vital mechanisms are conserved through evolution and function in the same way in eukaryotic organisms.

    A cell is the smallest functioning unit in an organism, is usually has one or more nuclei that’s surrounded by cytoplasm and all together it’s covered by a membrane. The membrane that surrounds the cytoplasm where substances can pass in and out of the cell making the cell membrane semi-permeable because that’s when only certain small molecules are able to pass through. Molecules can get across the cell many different ways; one way is through diffusion which is when the net movement of a substance will go down in concentration and will continue to go down until it reaches a dynamic equilibrium. A way that water can get across the cell membrane is through osmosis which is the diffusion of water across a semi-permeable membrane.

    Cells are able to grow and reproduce. Cells reproduce by splitting and passing on their genes (hereditary information) to Daughter cells. The nucleus always divides before the rest of the cell divides. Therefore each daughter cell contains their own nucleus. The nucleus controls the cells activities through the genetic material DNA. The cells in a body are all the same except the gametes they were all made from one cell, the Zygote. This is the cell that was formed when two gametes from your parents fused.

  • Plasma Membrane Essay

    1557 Words  | 4 Pages

    Let’s find out first what it is plasma membrane and its function. The plasma membrane is the boundary between the cell and its environment. It regulates what enters and exits the cell. Plasma membrane plays a vital role in protecting the integrity of the interior of the cell by allowing only selected substances into the cell and keeping other substances out. It also serves as a base of attachment for the cytoskeleton in some organisms and the cell wall in others. Thus the cell membrane supports the cell and helps in maintaining the shape of the cell. The cell membrane is primarily composed of proteins and lipids. While lipids help to give membranes their flexibility and proteins monitor and maintain the cell 's chemical climate and assist in the transfer of molecules across the membrane.

    The Animal Cell is a little bit different than the Plant Cell for only a couple of reasons. One is how the Plant Cell has a cell wall and the Animal Cell doesn’t. The cell wall protects and gives structure to the cell. Then there is the Nucleus, which serves as a control center for the cell. Inside the Nucleus there are one or more Nucleoli. They are dense, granular bodies that disappear at the beginning of cell division and reappear at the end. Then you have the Cytoplasm. This is the watery material lying within the cell between the cell membrane and the nucleus. The Cytoplasm also contains organelles, which have specific functions in the cell metabolism. Then there are the Golgi Bodies, which serve as processing, packaging, and storage for the cell. These organelles package and ship things out. Another parts of the cell, a very important one in fact, are the Lysosomes. These organelles are used to break things down and contain enzymes.

Cell walls, along with cellulose, provide support for plants so that they can grow tall while maintaining their shape. The size of the plant will determine the amount of cellulose it will need, but all plants require some amount of it and make use of it constantly.
