NUCLEUS AND THE GOVERNMENT
The nucleus is alluded to as the heart of the cell. The nucleus houses the hereditary material of the living being which is the DNA. DNA replication and RNA blend happens in the nucleus. It controls the exercises of the other cell organelles subsequently an imperative cell organelle. The cell nucleus is bound by a distinct layer called the atomic film that isolates the nucleus from the cytoplasm. The nucleus regulates all activity of the cell by controlling the enzymes. The government on earth emulates this as it creates laws and keeps the people in order. Both of these forces carry out decisions and controls that make the cell\Earth able to function. They both make final decisions that is recognized by all the

other things. It is especially recognized by the Nucleolus. CELL MEMBRANE AND THE ATMOSPHERE Cell membranes protect and organize cells.
All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in. All cells are contained by a cell membrane that keeps the pieces inside. The cell membrane is a protective layer that surrounds the cell and acts like a barrier. It separates the cell's contents from the outside environment. It is made up of a double layer of lipid: fat and phospholipids. The phospholipids have hydrophilic heads and hydrophobic tails which means that the heads are attracted to water and the tails are not. These phospholipids on the cell membrane equip it with the ability to keep certain materials out of the cell. That is why the cell membrane is called selectively permeable or semipermeable. The Earth's atmosphere is what keeps the Earth's surface from being completely obliterated. It is made up of many layers, which makes it hard for foreign materials such as asteroids to pass through it and crash into the Earth's surface. It also keeps out the sun's rays and harmful …show more content…
radiation. The atmosphere and the cell membrane both have multiple layers and both keep out foreign substances. The cell membrane separates the cell's contents and its environment in the same way that Earth's surface is kept separate from space.CYTOPLASM AND OCEAN AND LAND The cytoplasm is the gelatin-like substance inside the cell and everything inside of it, excluding the nucleus. The cytoplasm main function in the cell is to keep things moving by constantly flowing.It is made up of mostly water and salt. Cytoplasm is responsible for giving a cell its shape. It helps to fill out the cell and keeps organelles in their place. Without cytoplasm, the cell would be deflated and materials would not be able to pass easily from one organelle to another.The ocean covers seventy percent of the Earth and the land is the other thirty percent. The ocean is always flowing and the land is always changing.The cytoplasm and the ocean are both liquids that are always flowing. The land and the organelles of a cell are their contents, which make them part of the cell.VACUOLES AND LAKES AND PONDS In animal cells, vacuoles are places for temporary storage of waste, water, and other materials.
Therefore, since they are only for temporary storage, they are very small in animal cells. Lakes and ponds are like vacuoles in an animal cell. Lakes and ponds get their water from runoff and precipitation. Unlike the ocean, which always has water, lakes and ponds can dry up. The water isn't always there.Vacuoles and lakes both act as temporary storage. The lakes do not have the same water forever and the animal cell vacuoles do not have the same waste and water forever; it moves on. The vacuoles in an animal cell are also small and the amount of lake water compared to the world is also very small.MITOCHONDRIA AND POWER PLANTSMitochondria is responsible for converting glucose into energy that allows the cell to "live" and grow, creating and storing it to provide energy for the cell.The mitochondria are the powerhouses of the cell. They produce energy in the form of ATP by breaking down sugars. The cell uses the ATP to do work.Power plants are like
mitochondria. Power plants take raw materials and turn them into a usable form of energy. There are many raw materials that are used to make energy: water, wind, waste, etc. These power plants give us energy in the form of electricity and we use that electricity to make things better.They both make energy into a usable form. Both make energy that helps the organelles or people make a better functioning cell or Earth. Power plants follow a similar function on Earth of creating and storing energy for us to use to allow us to function as well.
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 floors of the grocery store is like the cytoplasm, because it hold everything in it place, where it need to be. The illes in the store is
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.
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.
parts, and each part has its own job. The nucleus of a cell is very similar
In the most general terms, the nucleus is the command center of a eukaryotic cell. Although the origin of the organelle is unclear, it is believed that it is derived from a symbiosis relationship between a bacterium and an archaea (Martin W. 2005). Being the main hub for the inner workings of a cell involves different functions overall. These nucleic functions are determined by the genes within the DNA of the cell. Functions of the cell are also regulate by soluble proteins that come in and out of the cell via the membranes and specific channels or the nuclear pore complexes. The overall objectives of the nucleus include; gene expression, compartmentalization, and processing pre-mRNA. The functions of the organelles and sub-regions
“The plasma membrane is the edge of life, the boundary that separates the living cell from its nonliving surroundings. The plasma membrane is a remarkable film, so thin that you would have to stack 8,000 of these membranes to equal the thickness of the page you are reading. Yet the plasma membrane can regulate the traffic of chemicals into and out of the cell. The key to how a membrane works is its structure” (Simon, 02/2012, p. 60).
The nucleus contains genetic material that controls all the activities within a cell. A nucleus is made up of D...
The mitochondria produces food for the cell by converting energy the cell needs. The mitochondria and the nucleus are two organelles within a cell that have many of the same similarities. Both organelles are made of two membranes. These layers isolate within the organelle all things considered, yet have protein channels that permit things to go in and out. Both contain DNA material that conveys qualities that encode for proteins. Both have qualities that make ribosomes, the machines that read the guidelines in RNA to make
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.
The mitochondria is an organelle which is generally an oval shape and is found inside the cytoplasm and is again apart of the eukaryotic cells. The main function of the mitochondria is to complete cellular respiration; in simple terms it acts like a digestive system to break down essential nutrients and to convert it into energy. This energy is usually found to in ATP which is a rich molecule taken from the energy stored in food. Furthermore, mitochondria stores calcium for signalling activities; such as heat, growth and death. They have two unique membranes and mitochondria isn’t found in human cells like the red blood cells yet liver and muscle cells are filled entirely with mitochondria.
Mitochondria are small granular or filamentous bodies which are called the power house of the cell. They are associated with cellular respiration and are the sources of energy. In 1850, the German biologist Rudolph Kolliker first observed mitochondria as granular structures in striated muscle [Powar, C.B. 2010; Albert et al. 2010]. In 1898, the scientist Benda developed the crystal violet staining technique and called the structures mitochondria. The average length of the mitochondrion is 3-4 microns and the average diameter 0.5 to 1.0 micron. In muscles, most of the mitochondria are 2-3 microns long. Mitochondria have different shapes. The number of mitochondria is different in different types of cells of different organs. They are distributed evenly in the cytoplasm. In sperms they are present in tail, in muscles they lie between the myofibrils. Mitochondria may move freely in some cells. Where ever ATP required. Movement is less in animals than plants. In plants they change their shape and volume [Powar, C.B. 2010; Albert et al. 2010].
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.
The membrane surrounding the nucleus in eukaryotic cells, separate the nucleus from the cytoplasm. Most of the cells we used in the experiments held, were multicellular or consisting of more than one cell. A variety of cells were used in completing the experiments. We used union cells, cheek cells, potato cells, and Elodeo cells. We also used Planaria which is a unicellular organism.
membranes and are also a component of energy depositing molecules like the ATP and ADP.
