Define:
a. Unicellular Organism Any living being consisting of a single cell. Most are invisible without a microscope but a few, such as the giant amoeba, may be visible to the naked eye. The main groups of unicellular organisms are bacteria, archaea, protozoa, unicellular algae, and unicellular fungi or yeasts. Some become disease-causing agents (pathogens). b. Colonial

    I noticed a few differences in in the various tissues/organelles, such as color and structure. For example, the plant epidermis was a teal color with a purple nucleus, and the spirogyra was more of a green color with a brown colored nucleus. Next, the plant epidermis had a structure that was more close together. On the other hand, the spirogyra had a structure that wasn’t as close together and more spread…

    Purpose and Background Cells divide in two ways, mitosis and meiosis. Mitosis is used to produce cells that are genetically identical to the parent cell for growth, asexual reproduction, or repair after injury. Cells that are produced by mitosis are diploid, meaning that they have two complete sets of chromosomes, one from each parent. Meiosis is used to produce haploid cells that have only one set of chromosomes, a mix of chromosomes from both parents. Meiosis produces cells that are genetically unique from their parent cells.…

    Interactive Question 7.2 Cite some experimental evidence that indicates that membrane proteins drift. A good form of experimental evidence is Fluorescence Recovery After Photobleaching, aka FRAP. In the FRAP process, membrane proteins are labelled with a green fluorescent protein, and part of the plasma membrane is “bleached” with a laser, causing them to lose their fluorescence. The part that was bleached will eventually become fluorescent again, as molecules drift in by diffusion.…

    A macromolecule is a molecule that contains any "large number" of atoms. There are four main different categories of macromolecules that make up our body: carbohydrates, lipids, proteins, and nucleic acids. (1) Carbohydrates are sugars that store and transport energy. (2) Lipids also store energy and also are signalling molecules. (3) Proteins are linear chains of amino acids that help with the structure, function, and regulation of the body’s tissues and organs.…

    Characteristics of living cell Cells are considered as the most fundamental unit that has the responsibility to carry functions within a living organism (De Robertis & De Robertis, 2006). The characteristics of living cells are: Cell Membrane: A protective layer that is surrounded to protect from its organelles and is made of bi-layer of a molecule known as phospholipids. A cell membrane also facilitates the transportation of molecules…

    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.…
