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

    b-The nucleus is an organelle found in eukaryotic cells. Inside its fully-enclosed nuclear membrane, it contains the majority of the cell's genetic material. This material is organized as DNA molecules, along with a variety of proteins, to form chromosomes. The main function of the cell nucleus is to control gene expression and mediate the replication of DNA during the cell cycle.…

    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…

    These nucleoli are responsible for ribosome production. If the nucleus were to suddenly malfunction, this would mean that the cell would have no directions, and nothing to direct them, so all activity would completely stop. Cell Membrane: The cell membrane is the organelle in the cell which determines what can come in and out of the cell. The cell membrane itself is a double layer of phospholipids, and this appears…

    7. How is the structure of a lysosome related to its function? Lysosomes are membranous sacs that contain digestive enzymes also known as hydrolytic enzymes. This allows it to breakdown macromolecules, damaged organelles, and pathogens inside the cell. Phagocytosis is the process of engulfing other organisms or particles with digestive enzymes.…

    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.…

An electron microscope would be better than a light microscope because an electron microscope allows you to view objects much smaller than you can with a light microscope. It might be better to use a light microscope if you are viewing a live specimen and do not want to kill it. 2. Prokaryotic cells are small, simple, no nucleus, no membrane-bound organelles, single loop of DNA (nucleosome), no cellulose, cytoplasm, cell membrane, cell wall (made of carbs), sometimes have cilia or flagella (movement).…

    A. The cell membrane is made up of phospholipids, cholesterol, proteins, and carbohydrates. The phospholipids and cholesterol both help create the roof of the cell membrane and they both regulate the fluidity of the cell membrane. The proteins in the cell membrane help provide a structural function, transport function, and signaling function all within the membrane (Yeagle, 1989). The carbohydrates are on the external side of the cell membrane. Also the carbohydrates provide a signaling function with the proteins and lipids.…

    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.…

    These go about as a boundary to keep DNA inside the core where interpretation happens. The RNA produced amid interpretation is transported out through atomic pores. Numerous proteins are integrated at the Endoplasmic reticulum. The ribosomes tie to the ER (a film bound organelle) and make an interpretation of the RNA message into protein that either navigates the layer (like a protein channel does) or is inside the ER in a vesicle (for solvent proteins that are emitted by the cell by exocytosis... like development elements and hormone proteins) (Meiner,…

    The cell is like a large well-oiled machine in the sense that each individual organelle has its own job to do, and if even one part fails to do its job, the entire body would shut down. The cell is composed of many organelles that are protected by the outer wall of the cell, called the plasma membrane. The plasma membrane is a flexible, but sturdy barrier that surrounds and helps contain the cytoplasm of the cell (Tortora P65). The main purpose of the plasma membrane is to protect all of the intracellular structure from its external environment and to determine what passes through and what is not permitted. The permeability of the plasma membrane is different for each substance.…

    Secondary lysosomes digest extracellular material of which is engulfed into the cell by a process called endocytosis. A phagocytic vesicle is pinched off from the cell plasma membrane and encloses the material to be digested. This vesicle fuses with the lysosome to form a phagolysosome complex. The acidic environment denatures macromolecules to increase their surface area for hydrolases to act. Once broken down, the soluble, useful material such as sugars, amino acids and nucleotides are used by the cell as nutrients; they enter the cytosol through the lysosomal membrane by either facilitated diffusion or active transport.…
