Prokaryotic And Eukaryotic Cells Essay

Improved Essays
Cell membrane- A cell membrane is a fine structure that can also be referred to as a plasma membrane. Both Eukaryotic and prokaryotic cells are enclosed by a cell membrane. The functions are to keep a steady shape of the cell and to control particles moving into and out of the cell. These particles may be ions or molecules.
Cell wall- Prokaryotic cells have a cell wall whereas eukaryotic cells don’t. The cell wall is what provides shape and protects the cell components.
Nucleus- Nucleus is only found in eukaryotic cells. The structure of a cell’s nucleus is membrane bound and contains chromosomes which consist of DNA. The nucleus maintains the integrity of genes and controls the activities of the cell. The nucleus is referred to as the control centre.
Mitochondria- Prokaryotic cells do not have mitochondria whereas eukaryotic cells do. They are made up of two membranes. The outer membrane acts as the

The role is to form proteins by assembling amino acids. The proteins are needed to carry out the cells activities.
Endoplasmic reticulum- These are only found in eukaryotic cells. It is made up of sac like structures and held together by a cytoskeleton. Rough endoplasmic has a surface dotted with proteins and the smooth endoplasmic is made up of tubules which increases surface area. They insure there is more surface area for cell reactions. Also involved in making nuclear membranes during the division of cells. Carbohydrates and proteins are transported to different organelles including lysosomes and plasma membrane.
Golgi body- they are only found in eukaryotic cells. It is made up of sac like membranes which are stacked. The structures are known are cisternae. The main role is to sort, package and modify molecules that have been synthesized by cells. They also create lysosomes and transport lipid

    There are many organelles in the animal cell. There is the nucleus, endoplasmic reticulum, cell membrane, vacuoles, lysosomes, mitochondria, cytoplasm, ribosomes, & golgi apparatus. The nucleus directs all the cells activities,including reproduction. Endoplasmic Reticulum is a network of membranous tubules within the cytoplasm continuous with the nuclear membrane;It usually has ribosomes attached The cell membrane protects the cell and regulates what substances can enter and leave. Some animal cells have vacuoles that store food, water, & waste. Lysosomes are small organelles that break down food particles and worn-out cell parts. Most of the cell’s energy is produced in the mitochondria.Cytoplasm is gel-like fluid which many of the organelles are found. Ribosomes function as factories to produce proteins which can either be attached to the endoplasmic reticulum or float in the cytoplasm. The golgi apparatus receives materials from the endoplasmic reticulum and send them to other parts of the cell…

    The nucleus is the largest of all the organelles in an animal cell, it is known as the control centre. The structure of the nucleus contains a nuclear membrane, chromosomes, nucleolus and a cytoplasm. The nucleus is a sphere shaped organelle which is found in eukaryotic cells. This organelle does most of the functions throughout the animal cell. It is responsible for most of the genetic material, which is DNA and RNA. The RNA moves in and out of the nucleus through the pores of the nucleus membrane. The Nucleus is also in charge of protein synthesis which also enters through the nuclear…

    The most critical eukaryotic organelle to the cell would be the nucleus. The nucleus is the central and most important part of a cell (Daempfle, 2016). It serves as the city hall of the cell. A nucleus is usually centered within the cytoplasm. Also, a nucleus contains the genetic material that produces and controls the cell's parts; it communicates with the rest of the cell by instructing the production of proteins which serve many roles especially in chemical reactions.…

    The outer membrane shields the organelle and represses it like a skin (3). It also allows the passage of smaller molecules that contain mitochondrion sequences. The inner membrane folds over many times and produces layered structures called cristae (4). The folding of the inner membrane increases the surface area inside the organelle. Since many of the chemical reactions happen on the inner membrane, the increased surface area creates more space for reactions to occur (4). If you have more space to work, you can get more work done. The fluid held inside of the mitochondria is called the matrix. There are also structures called granules which may control concentrations of ions. Mitochondria are special because they have their own ribosomes and DNA floating in the matrix…

    In a cell, all of the organelles are a necessary part of the whole. The nucleus is the brains of the cell. The nucleus is also where the DNA is located. DNA are the proteins that hold the genetic code necessary for the cell to replicate. The DNA replication takes place in the ribosomes, where the proteins are translated in order to be replicated. The plasma membrane covers the entire cell and oversees the flow of chemicals that come both in and out of the cell. The plasma membrane creates a clear, definitive boundary for the cell. The mitochondria is where cellular respiration takes place. Cellular respiration is an important cell cycle that breaks down sugars, separating the energy so the cell can actually make use of the energy and perform…

    They are described as the ‘powerhouse’ of the cell. They are organelle that takes in nutrients, breaks them down, and creates energy for the cell. This is known as a cellular respiration. Mitochondria are described like a sausage-shaped structure. It has a double membrane and it controls what enters and exit’s the mitochondria. It has the outer membrane and the inner membrane. Outer membrane are described smooth and is composed of equal amounts of phospholipids and proteins. The inner membrane is more complex and is folded into a number of folds called cristae. It increases the available surface area where respiratory processes take place. The rest is called the matrix. In length the mitochondria varies from 1um to 10um and in width from 0.25um to 1.0um.

    Eukaryotic cells come in a variation of forms. Some can be single-celled organisms that are generally bigger than prokaryotes. Human adults are made up of about 100 trillion cells of over 200 distinctive types. Internally, eukaryotic cells are considerably more complex than prokaryotic cells. The prokaryotes as well as the eukaryotic cells are enclosed in a spoongy cell membrane, but unlike prokaryotes, eukaryotes also have membranes within the cell that enclose tiny intracellular compartments where essential functions and processes can occur in isolation from the rest of the cell. The inside of the eukaryotic cell is a highly structured and organized, consisting of eukaryotic cells which externally may be bare or have cell walls, flagella, or cilia. In addition to that, they have internal…

    A cell is the most basic structure of any living organism and is capable of independently reproducing. Cells can be grouped into two categories, prokaryotic and eukaryotic. In a eukaryotic cell there are small organelles that carry out specific functions which can be compared to the organs in the human body. Some of these organelles include the nucleus, which holds the cells DNA, mitochondria, which produce ATP from glucose and oxygen, known as cellular respiration, and the golgi body which packages and processes different substances leaving the cell. Prokaryotic cells are the simpler of the two cells and are single celled organisms, such as bacteria, that don’t contain organelles.…
