nutrients, waste, and ions. The cell wall acts like a skeleton by helping the plant maintain its shape and sturdiness. Without a cell wall plants would not be able to keep their shape. The cell wall is made out of cellulose. One of the most abundant macromolecules on earth is cellulose. Cellulose is a type of sugar that is not used for energy but rather for structure. It does not dissolve in water and only cows and other herbivores can digest cellulose with cellulose polymers. Without the

asddsaProteins (/ˈproʊˌtiːnz/ or /ˈproʊti.ɨnz/) are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues. Proteins perform a vast array of functions within living organisms, including catalyzing metabolic reactions, DNA replication, responding to stimuli, and transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and

Introduction Centrifugation is a process used to separate or concentrate materials suspended in a liquid medium. The theoretical basis of this technique is the effect of gravity on particles (including macromolecules) in suspension. Two particles of different masses will settle in a tube at different rates in response to gravity. Centrifugal force (measured as xg, times gravity) is used to increase this settling rate in an instrument called centrifuge. Centrifuges are devices used in a variety

In-vitro bioassay models have been made to understand the repair mechanism of mesenchymal cells. Fibroblasts, type of mesenchymal cell, produces the extracellular macromolecule fibronectin which mediates the interaction between cells and extracellular

Organelles are components of eukaryotic cells, which act as functional units. A simple eukaryotic cell comprises of many organelles such as the mitochondria, vacuole, or nucleus. These organelles are responsible for the preservation of the cells function and vitality. Each organelle is dutiful to a specific role essential to the cell, and thus the greater organism. However, which of these organelles is the greatest contributor to cell vitality is widely debatable. Fundamentally, there is one organelle
