Prokaryotic And Eukaryotic Cells Essay

Good 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

    The ribosomes take the template and hook together amino acids to create a polypeptide chain, protein. The protein made by free ribosomes is used in the cytosol, while bound ribosomes make protein to be used in the cell membrane or to be exported from the cell. In our cell, the ribosomes are represented by the sweet tart minis. The orange sweet tarts are the free ribosomes and the yellow are bound to the endoplasmic reticulum. Rough Endoplasmic…

    The nucleus serves as the control center of the cell. It is responsible for directing the cell in its functions and it also stores the DNA. It is made up of three main parts: the nuclear membrane, the nucleolus, and the genetic material also known as DNA. The nuclear membrane is made up from the nuclear envelope and nuclear pores. Like the plasma membrane, the nuclear membrane separates the nucleus from the other organelles and contents of the cell.…

    In prokaryotes, the DNA is in the cytoplasm, but specifically it is concentrated in the nucleoid region. In eukaryotes, the DNA is all contained and stored in the nucleus. Prokaryotes and eukaryotes also contain ribosomes. Ribosomes are small, roughly spherical organelles without a membrane that are responsible for assembling and building protein. Ribosomes are composed of protein and RNA molecules.…

    There are two main types’ of cells. These are prokaryotic (see diagram 1) and Eukaryotic. ( See diagram 2). Prokaryotic cells are the cells of microorganisms such as Bacteria and Achaea. Eukaryotic cells are basically cells that make all other living things such as humans and animals.…

    ER is made of two different types, smooth and rough. Centrosomes are also present and they contain important spindle fibers which develop during the process of cell division. Main Functions: Endoplasmic Reticulum- a network of tubular membranes within the cytoplasm of the cell, occurring either with a smooth surface (smooth endoplasmic reticulum) or studded with ribosomes (rough endoplasmic reticulum) involved in the transport of materials. Nucleus- a dense organelle present in most eukaryotic cells, typically a single rounded structure bounded by a double membrane, containing the genetic material (Contains: nuclear pore, nucleolus, nucleoplasm, and nuclear envelope) Golgi Apparatus- a complex of vesicles and folded membranes within the cytoplasm of most eukaryotic cells, involved in secretion and intracellular…

    The relationship between codons and amino acids is known as the genetic code where it defines how sequences of codons specify which amino acid will be added next. Ribosomes are large structures within the cytoplasm that house the translation process and catalyze some of its steps. These structures are made up of ribosomal RNA (rRNA) and protein subunits that provide a space for tRNA to bind to an mRNA template. Each ribosome contains 3 binding sites known as the A,…

    “Phospholipids make up the basic structure of a cell membrane.” (“Cell Membrane: Functions, Role, and Structure,” 2003) It is not a solid. Some of the things the plasma membranes need in order to carry out it’s functions is lipids, proteins, and carbohydrates. They move freely and fluidly in the plane of the membrane. Lipids, made up of glycerol, two fatty acid tails, and a phosphate- linked head group, are used to make a barrier between the cell and its environment. Phospholipids are the main fabric of the membrane.…

    SNARE Proteins Membrane fusion is a function of cell division and cell growth. The machinery used in membrane fusion is also a component of memory and learning. SNARE (soluble N-ethylmaleimide-sensitive fusion protein attachment protein receptors) proteins function in membrane fusion. They also ensure specificity in regulating membrane docking and fusion in exocytosis process and at the pre-synaptic plasma membrane. There are questions regarding how SNARE proteins specificity is enacted and controlled.…

    The nucleus is surrounded by a nuclear envelope, which can also be referred to as the nuclear membrane which is a bilayer membrane that encloses the contents of the nucleus throughout the lifecycle of the cell. The membrane of the cell is selectively permeable meaning that it only allows certain things to go in and out. The cytoplasm which is surrounded by…
