All cells, whether it is a prokaryotic cell or eukaryotic cell, have ribosomes. Ribosomes are small non membrane bound organelles that make proteins. Every cell needs proteins to survive. Without them, a lot of the life processes like reproduction, excretion, respiration and growth wouldn’t happen.
Both prokaryotic and eukaryotic cells have some sort of genetic material, which is DNA. Prokaryotic cells have circular DNA, while eukaryotic cells have more linear DNA. DNA is a compound molecule that contains the genetic material of a cell and the information on how to make proteins. It controls the function and structure of a cell.
All cells also contain organelles. Organelles are small units in a cell's cytoplasm that performs specific tasks and carries out life processes. You can think about organelles as the organ of a cell. as a mini organ. Most organelles are surrounded by a membrane, however, some can float around freely in the cytoplasm.
Prokaryotic and Eukaryotic cells both have cytoplasm. Cytoplasm is the fluid in a cell.

Deoxyribonucleic acid (DNA) is a molecule found in all forms of life that is passed down from parents to offspring. What makes each DNA unique is the chemical makeup of the molecule sometimes referred to as the “blueprint of life.” (BIO). DNA is made up of nucleotides consisting of a sugar, a phosphate and a base pair. About six million nucleotide base pairs make up DNA in each cell.
1. Nucleus- present only in eukaryotic cells, this structure stores most of the genetic information of the cell. The nucleus directs the production of proteins through the synthesis of mRNA. 2.
1. Cell Membrane - A cell membrane in a cell is like the turnstiles and gates of a baseball stadium. The cell membrane is selectively permeable and the turnstiles or gate only let people with a ticket into the stadium 2. Cell Wall - The cell wall in a cell is just like the support beams of a baseball stadium.
Organelles as organism is from The Lives of a cell authored by Lewis Thomas. Thomas uses a unique writing style that is very recognizable and different from the others. This helps us to appreciate our diversity as human beings demonstrated by our abilities to write differently. As a reader one is able to form an image of who Thomas is by how he expresses his feelings and attitudes. When this text was written a lot of people, mostly scientists, thought and had knowledge of different things than they do now.
Nutrition is the process of providing or obtaining the food necessary for health, growth, metabolism, and repair. Food is separated into two groups of requirements; macronutrients and micronutrients. Macronutrients is defined by types of food that are highly required and a bigger amount of them in the diet. Examples of macronutrients would be: carbohydrates, proteins and fats.
How Should the Unknown Organism Be Classified? Introduction: In science taxonomy is used to classify different organisms into the hierarchy of taxonomy, this helps separate organisms by species, genus, family, class, phylum, kingdoms and domains and allows for comparing and contrasting of different organisms. The question presented to our group was "How should the unknown organism be classified?".
Introduction As we all know, bacteria is a very complex organism and the subject can be very broad. In this essay, the focus will be on bacteria and the bacterial cell structure. Different forms of bacteria, its pros and cons, the cell structure, diseases and resistance will be explained and listed. First bacteria and cell structure is explained, and then moving on to different bacterial forms and diseases, and how diseases can be prevented or even cured. Then finishing the essay will be the conclusion.
Even though we cannot see cells without a microscope, they are the basic unit of life and they exhibit all of the characteristics of living organisms. They can exist individually, as do bacteria, or they may work together, taking on specialized tasks to create a more complex organism. However, all living organisms share certain characteristics, which are discussed below. Cells are made of cytoplasm.
What comes to people’s mind when they hear the word “animal’? Most people will picture a furry creature with four legs such as a dog or a cat in their mind, but none will picture a sand dollar even though it’s an animal. Most people would find it’s difficult to label a sand dollar as an animal. To begin with, it doesn’t even look like a living thing; it looks like a flat piece of rock. Secondly, sand dollar looks nothing like a typical animal that people see daily; it doesn’t seem to have animal-like characteristics.
In the next page we begin to describe the daily functions of a cell and start to introduce the cell cycle. Page five demonstrates how cells or the citizens of the kingdom contribute in many ways. For example, making food for the Kingdom exemplifies the ribosomes of the cell creating proteins and the protecting of John imitates the functions of the cell membrane. After explaining the purpose of cells we describe the checkpoints of interphase using
DNA has a massive job of keeping you alive. In essence, a microscopic strand of genes support your entire body and life. There are many smaller jobs protein has to accomplish that combine to accomplish the main job of supporting life. To start, DNA codes for proteins and every protein provide an essential biological function. Also, cells make up tissues, organs, and body systems.
The Diverse Parts of Macromolecules in Science There are four sorts of macromolecules that I am going to portray: Proteins, starches, lipids and nucleic corrosive. I will likewise depict the capacities and why they are critical in our bodies. Proteins Proteins are polymers of amino acids that are joined head-to-tail in a long chain that is then collapsed into a three-dimensional structure one of a kind to every sort of protein. The covalent linkage between two contiguous amino acids in a protein (or polypeptide) chain is known as a peptide bond.
DNA is a complex molecule containing the genetic information that makes up the chromosome. Genomes are the complete instructions for making an organism, consisting of all the genetic material in that organism’s
Thus they are both intracellular and extracellular. 1. Lysosome cell organelle has
Bacteria usually have capsules, but archaea rarely have one. Inside the prokaryote is cytoplasm and a nucleoid. The nucleus is not enclosed inside of a membrane in prokaryotes. The cell may have appendages to adhere to certain surfaces or for motility. The prokaryotic cell is smaller than the eukaryotic cell and has different qualities that make the cell less complex than a eukaryotic cell.
