Differences Between Eukaryotic And Prokaryotic Cells

Question 1

There are a lot of important differences between eukaryotic and prokaryotic cells. The differences include size, shape, function, and processes. The Greek meanings of these words translate to prokaryotic cells having no nucleus and no membrane bound organelles, but eukaryotic cells do have a nucleus and membrane bound organelles. There are many differences between these two cells but there are four most important differences. The biggest difference between the two is that the eukaryotic cells have a defined nucleus and prokaryotic cells don’t have a defined nucleus. The nucleus is the brain of the cell and site for genetic transport. The DNA in the prokaryotic cells float around in the nucleoid while the DNA in a eukaryotic cell

The ribosomes are the site of protein synthesis. The endoplasmic reticulum is the site for cellular chemical reactions. The Golgi apparatus receives proteins from the ribosomes and sends them to their designated areas (like a post office). Vacuoles are sacs around the membrane that are used for storage of food, and enzymes. The lysosomes are used for digestion. The mitochondrion is the powerhouse of the cell and produces the ATP that the cell needs. Chloroplasts gather light energy to produce ATP and form sugar from carbon dioxide. Prokaryotes do not contain membrane bound …show more content…
Prokaryotic cells reproduce by binary fission. This means that the cell produces asexually. The single circular DNA chromosome replicates and the original cell is divided into two identical daughter cells. This means that each daughter cell has the same exact DNA that the parent cell does. Eukaryotic cells reproduce by mitosis. In mitosis there are four basic steps; prophase, metaphase, anaphase, and telophase. The end result is two identical daughter cells that have the same structures and number of chromosomes as the parent cell had. Each reproduction cycle for both prokaryotes and eukaryotes have the same end result, it’s what happens in the cycle that makes the difference. The last main difference between the two cells is the size of them. Prokaryotic cells are only 1-10 um while eukaryotic cells are much bigger at 10-100 um. The reason for this is because eukaryotic cells contain a nucleus and membrane bound organelles so it needs more room inside the cell. The prokaryotic cells are not as big because they don’t contain as many organelles as the eukaryotic

    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…

    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-…

    Characteristics can classify organisms into 5 key groups called the 5 kingdoms: - Protoctista: These are mainly unicellular organisms that also have a nucleus. Some examples of protoctista are paramecium, amoeba and unicellular algae. -Prokaryotes: These are also unicellular organisms like protoctista but unlike them, they do not have a nucleus. An example of a Prokaryote is bacteria.…

    Cell Biology Beta cells in pancreatic tissues are described as eukaryotic cells and not prokaryotic, this is because the cell is larger in size and there is a true nucleus present which contains DNA. In prokaryotic cell there isn’t a nucleus and the DNA is free within the cytoplasm. Also Beta cells have many organelles and there is mitochondria present, which in a prokaryotic cell there are fewer organelles and there aren’t any mitochondria present. Beta cells in the pancreatic tissue release insulin when blood sugars are high, in order for insulin to be released it needs be produced and the insulin is created by a process called protein synthesis.…

    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.…

    INTRODUCTION Cellular respiration is the breaking down of organic molecules by means of catabolic pathways that uses electron transport chain to produce ATP (Campbell 2011). ATP is used as energy in the synthesis of light or also known as Photosynthesis . ATP is used by photosynthetic organisms to produce their own food and also by performing cellular respiration. It needs mainly glucose and oxygen that involves the transfer of electrons in a chemical reaction.…

In cell division process the cell is obtained by the already existed cell or pre existed cell stated by Ruolf Virchow in 1855. The process divison of cells is uasuall same in all of the living organisms. Division of cells is furtherly divided into two types :- 1) Mitosis 2) Meiosis Basic Difference Mitosis and Meiosis:- Mitosis and Meiosis both are originally types of division of cells .…

    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.…
