    the exchange of materials with its surroundings. It is a permeable membrane that surrounds the cytoplasm. The contents held within the plasma membrane are called cytoplasm. In prokaryotes, or single-celled organisms, it is the only membrane. In eukaryotes, cells that contain a nucleus, the organelles are also surrounded by a plasma membrane. The membrane controls all exchanges between the inside…

    heterotrophic cells are able to consume its own food instead of relying on the sunlight allowing them to consume nutrients any time of the day whether there is light available or not. This allows the heterotrophs whether they are prokaryotes or eukaryotes to be more diverse and survive through many…

    of prokaryotes to form multicellular organisms.” This is compared to the internal skeleton strucutre of Eukaryotes, where “it is formed by a complex of protein tubules called the cytoskeleton.” (K S Kabnick and D A Peattie, 1991.) This difference in structure gives a pliable membrane to the cell rather than a rigid cell wall. This increases mobility of many Eukaryotes which is essential for the specific function within organisms, for instance, muscles cells need to have the…

    Mitochondria Lab Report

    • 2252 Words
    • 10 Pages

    Introduction: - Mitochondria is a double membrane organelle that is found in all eukaryotic organism. There are some evidences that proves that some of the eukaryotic organism lack this organelle but there is no true evidence which says that this specific organism completely lacks mitochondria. Mitochondria is also known as a power house of the living body cell. It stores energies in the cell and releases when its needed. Every organelle in Mitochondria have their own specific roles which helps…

    So there is definitely and qualitative and quantitative in size difference. Eukaryotes have a nucleus membrane bound that bacteria doesn’t. So the difference in general between bacteria and eukaryotes is that genetic information is formed in protein and is converted into organization, function and cellular structure. Eukaryotes also have a replication of machinery that is found in bacteria but are more complex and larger. The phase of replication has…

    Prokaryotes There are two types of organisms based cell types: Prokaryotic and Eukaryotic. Prokaryotic cells are divided into two parts: Bacteria and Archaea. Prokaryotes are much smaller than eukaryotes. Prokaryotes contain a single loop of chromosomal DNA which is stored in nucleoid. Eukaryotes DNA is found on tightly bound and organised chromosomes. Genetic expression is the process where genotypes coded in the genes are displayed by the phenotypes of the individuals. The DNA is then copied…

    In this lab I examined and drew different samples of slides and then categorized these slides into a logical evolutionary order. The first sample that most likely came first in the evolutionary order is the typical bacteria, which I viewed at a 1000 magnification. These bacteria can be found in the Eubacteria domain and kingdom. The bacteria in my sample were coccus, which means that the bacterium has a round shape, and this type of bacteria is one of the simplest forms of bacteria. These cells…

    In the first part of the lab we were able to study the diffusion of various carbohydrates and the osmosis of water. Diffusion is the process of small molecules moving through a semipermeable membrane while osmosis of water is the movement of water through a semipermeable membrane from an area of high water potential (low solute potential) to an area of low water potential (high solute potential). Both diffusion and osmosis move in the direction that would create equilibrium on both sides of the…

    For my project, I chose to make an illustration. In the picture I have a breast cancer ribbon, a pot of boiling water, a prokaryote, a chromosome, a pedigree, and a factory to represent human impact, a flower to represent photosynthesis, a food chain, an energy pyramid, an embryo, humans evolving, a biomolecules chart, and the phases of mitosis. I drew a breast cancer ribbon because we talked about different types of cancer. There are many factors that go into the diagnosis of cancer. A lot of…
