What Are Unicellular Organisms? Unicellular organism, also referred to as single celled organisms, is an organism that consists of a single type of cell. Life processes such as excretion, digestion, feeding and reproduction occur in one cell. They are typically microscopic in nature and cannot be seen with naked eyes. Many unicellular organisms live in … Read more
What Is MIG (Metal Inert Gas) Welding? Metal Inert Gas (MIG) welding is a welding process in which an electric arc forms between a consumable MIG wire electrode and the workpiece metal, which heats the workpiece metal, causing them to melt and join. The wire electrode is wrapped in a wire-pool and is continuously fed … Read more
What Is An Endoskeleton? An endoskeleton is a skeleton found within the interior of the body and therefore it provides structural support and support for the internal organs and tissues of an organism. An endoskeleton occurs in chordates including all the vertebrates. The endoskeleton of chordates develops from mesoderm tissue during embryonic development. The vertebrate … Read more
The xylem is the vascular tissue that moves water and nutrients from roots to various parts of the plant such as shoot and leaves. Major components of xylem tissue include: xylem parenchyma, xylem fibers, xylem vessels and tracheids. The tracheid is one of the two cell types of the tracheary elements, the other being the … Read more
Xylem and phloem are the major conducting tissues in vascular plants. The main function of xylem is conduction of water and minerals towards the apical shoot. Xylem tissues can be classified as primary and secondary xylem depending on where they originate. The primary xylem is the type of xylem that is produced from the primary … Read more
Xylem and phloem are part of the vascular tissues in vascular plants. Phloem plays a role of transporting food materials referred to as photosynthate from photosynthetic organs to different parts of the plant in a process referred to as translocation. Just like xylem, phloem tissues can be classified as primary phloem and secondary phloem. The … Read more
The phloem is the vascular tissue that carries out the function of translocation (i.e the process of transporting photosynthate materials from the photosynthetic plant organs to various parts of the plant. Phloem is made up of the following major components: Sieve element Companion cell Phloem parenchyma Phloem schlerenchyma In angiosperms, the sieve element is referred … Read more
Amylose and amylopectin are present side by side and interspersed in the starch granule. They have unique chemical and physical properties and their relative proportions influence the overall properties of starches. Amylose forms a colloidal dispersion in hot water whereas amylopectin is completely insoluble. What Is Amylose? Amylose also referred to as a linear polymer, … Read more
