CELL ULTRASTRUCTURE CELL ULTRASTRUCTURE Cells are the smallest functional units of the body‚ (Waugh‚ A. and Grant‚ A.2010). Most cells are microscopic. The largest cell in the body is the female ovum. The erythrocyte is the smallest cell. The longest cell is the neuron. Cells group together to form tissues‚ each of which has specialised function. Different tissues group together to form organs. Organs are group together to form organ systems‚ each of which performs a particular function that

phylogeny of the Chytridiomycota found Rozella was in fact part of a separate linage considered to be the most basal lineage within the fungal kingdom (James et al 2006). Analysis of environmental DNA samples based on the analysis of SSU RNA (small subunit ribosomal RNA genes)had revealed 26 sequences‚ previously unknown‚ which clustered closely to two species of Rozella included in the survey (Lara et al 2010). Lara et al tentatively named this clade ’Rozedilla’ (Lara et al 2010‚ Jones et al 2011)

a) Using a human cell of your choice‚ describe how organelles work together to make and secrete a protein (LO1. AC 1.1) An epithelial cell in the thyroid gland‚ called a thyrocyte forms spherical follicles that produce a protein called thyroglobulin. This is a globular protein that has a functional role in metabolism. The protein is used by the thyroid gland to produce thyroid hormones; thyroxine (T4) is an example of one of the hormones created. Thyroxine is formed by iodine binding to tyrosine

Third‚ Nucleic Acid‚ the functions of nucleic acid is storing genetic material‚ transferring genetic information called DNA and RNA to ribosomes for protein synthesis‚ that carries Amino acids into place and Polypeptide keeps the chain of amino acids together ‚also DNA is composed of nucleotides ‚and holds ribosomal subunits together‚ Deoxyribose replaces hydroxyl in groups . Four‚ Protein‚ The functions of proteins are structural support in things such as hair and nails

Unit 3 Lecture Study Guide 1. List the 4 primary tissue types and give the general characteristics and functions of each one. a. Epithelium - 1) It protects us from the outside world – skin. 2) Absorbs – stomach and intestinal lining (gut). 3) Filters – the kidney. 4) Secretes – forms glands. Characteristics (Traits): 1) Closely attached to each other forming a protective barrier. 2) Always has one free (apical) surface open to outside the body or inside (cavity) an

into individual strands‚ these bonds are broken‚ and you now have two strands with complimentary bases. RNA can then be created by using these individual bases‚ which is how DNA gets its message out of the nucleus (since it’s too large in size to fit through the pores in the nuclear envelope). Nucleotides are organic molecules that serve as the monomers‚ or subunits of nucleic acids like DNA and RNA. The building blocks of nucleic acids‚ nucleotides are composed of a nitrogenous base‚ a five-carbon
