Cell Analogy Essay
My analogy from a cell is to a city. A cell has a cell membrane and in a city the city border acts as the cell membrane. The city wall in a cell acts like a cell wall. The cytoplasm can be a lawn in a city. Highways or road systems act like the endoplasmic reticulum in a city. The ribosomes in a cell organelle can be considered lumber or brick yard in a city. In a city post offices and UPS act as the golgi bodies. Solar energy plants are considered chloroplast. A city hall fence with a security guard can be considered as the nuclear membrane. Energy plants in cities can be considered the mitochondria. In cell organelles there is the nucleus and in a city the nucleus would
All mammalian cells are eukaryotic, and whilst the eukaryotic type of cell is not exclusive to mammals, mammalian cells differ from other eukaryotic cells because of the organelles that are or are not present. For instance some plant cells have chloroplasts which are not present in mammalian cells, but both plant cells and mammalian cells are eukaryotic in nature. The term eukaryotic refers to the cell having specific membrane bound organelles, which are not present in prokaryotic cells. The defining feature of a eukaryotic cell is usually its membrane bound nucleus (the exception being the red blood cell) [1].
For a plant cell, the nucleus, without a doubt, is the most important organelle; but in the animal cell, the most vital structure is the mitochondria.
According to Mattias Schleiden and Theodor Schwann the cell is the basic unit of life(Cell Theory- OI). Two common types of cells are the plant and animal cells. Although both kinds of cells share many similar, abundant structures, they also have varying descrepancies from cell to cell. Without a doubt, the nucleus is the most important organelle in the plant cell, even though, the lysosome is the most important structure in the animal cell.
These parts are all paired to parts of cells. A quarterback is compared to a ER because it throws the whole game when he throws the ball. A cell wall is compared to the center because it protects the quarterback to throw the ball. A football field is compared to the cytoplasm because it is where all the players are at. A coach is like the nucleus because it controls the plays and tells the play. A golgi apparatus is compared to the running back because it sends the
There are many parts of a cell, they all have specific duties, and are all
Without the cells there will be no life. A cell is the the building block of the body. There 2 different types of cells there are animal cell and plants cells. Eukaryote is any cell that has a cell membrane bound. It also contains organelles.
Breaking down an organism leads scientists to identify cells. A group of cells create tissues, tissues combined are organs, and organs and their functions make up systems. Basically, cells make up living organisms. There are 2 kinds of cells: Prokaryotic and Eukaryotic. Within a prokaryotic, it doesn’t contain a DNA bounded nucleus; however, a eukaryotic cell does. Though the prokaryotic cell differs from a eukaryotic cell, they share a cell membrane. The cell membrane is composed of a phospholipid bilayer and proteins, which makes it selectively permeable. It is located outside of the cytoplasm and controls the movement of substances in and out of the cell. Its basic function is to protect the cell from its surroundings by selecting what can enter and exit the cell.
This is the story of a cell, a young cell. This cell’s goal was to have the most powerful mitochondria of any other cell she knew. The mitochondria gave energy. She knew if she had a strong mitochondria, her being would be powerful and strong.
I believe that a factory would be the perfect example of an animal cell because in order for a cell to work it needs to get rid of materials and also take some in.I also believe that the animal cell is a factory because like every factory there is a command center ( the nucleus). The nucleus gives orders to the organelles of what to do and, when compared to factories the command center of those factories give info to the workers for what to do. The nucleolus has another connection to a factory by making sure everything is working perfectly same as the command center of a factory. Also a factory is a lot like a animal cell in the sense of how the endoplasmic reticulum sends proteins through the cell giving enough energy to power itself.
Organisms in the Plantae and Animalia kingdoms are multicellular, eukaryotic, and have organelles such as a membrane bound nucleus. However, their organelles do vary. Plants have cell walls consisting of cellulose and have chlorophyll pigments which allow them to photosynthesize, while animals lack a cell wall and chlorophyll (Caprette 2005). Other plant cellular components include a plasma membrane, multiple plastids for pigment synthesis and storage (chromoplast) and storage of starch (amyoplasts), vacuoles to contain fluids, and mitochondrion which assist in energy production. Animal cells also have mitochondria and a plasma membrane, but have structures for movement such as cilia and flagella, and other complex structures.
inside. In addition to the Golgi apparatus is the postal service when it moves substances inside the cell. Hereby, we have mentioned various examples that's showed a clear usage do metaphors on objective writings about cells and to describe each organelle in simpler and as well more understandable methods. Another illustration about metaphors used in biology for describing cells is as follows: below the microscope, a cell looks a lot like a fried egg: It has a white (the cytoplasm) that's full of water and proteins to keep it fed, and a yolk (the nucleus) that holds all the genetic information that makes you you.
There are two types of cells known to humanity, eukaryotic cells and prokaryotic cells. Prokaryotic meaning” before or pro nucleus”, is a cell that has no nucleus; however does contain a plasma membrane, ribosomes, cytoplasm and genetic material (DNA and RNA). Occasionally some prokaryotic cells also may have a flagellum or pili- used for movement of the cell. Flagellum is a tail like structure, cells usually contain only 1 or 2,as for pili they are hair like structures and there are an abundance covering the cell; both structures hold within them cytoplasm and are enclosed by a plasma membrane.
In regards to their basic structure, according to the SEER Training website, “cells consist of three parts: the cell membrane, the nucleus, and, between the two, the cytoplasm.” (Training.seer.cancer.gov, 2017) This is true for animal cells however plant cells contain a fourth part which is known as the cell wall, it is located on the outside of the cell membrane and allows the cell to keep its rigid shape. It should also be known that there are types of cells that do not contain a nucleus, these are called prokaryotic cells and generally still have the same characteristics as cells that do have a nucleus which are known as eukaryotic cells. (Study.com, 2017) As seen in Figure 1 cells also contain organelles which keep the cell alive and allow it to function effectively.The cytoplasm of the cell which resides between the cell membrane and the nucleus is a gel-like liquid filling the inside of the cell. The cytoplasm allows the cell to have shape and allows the cell 's organelles to move around the cell as needed and function correctly. The nucleus is widely considered to be the control center or
Organelles are the internal structures of the cell that are important for the cell to survive. Each organelle has a specific function for the cell. The types of organelles in the cell can be different from each other depending on the type of cell. Plant cells and animal cells both have a cytoskeleton, endoplasmic reticulum (smooth and rough), golgi apparatus, mitochondrion, nucleus, plasma membrane, and ribosomes. Animal and plant cells also have vacuoles, but they are rarely found in animal cells. Vacuoles in animal cells are very small compared to the vacuoles in plant cells. Lysosomes are also rarely found in plant cells but mostly found in animal cells.
The cytoplasm is the area between the nucleus and the cell membrane. The cytoplasm contains many important structures. This area is basically the main place where you will find structures that help the cells stay alive.
