Hammer Head Shark Organ Structure and Functions The hammer head shark contains multiple organs that are suited for their environment in the Great Barrier Reef. Their skin‚ which is an integument organ‚ is made of an atmosphere of dermal denticles or placoid cells. These denticles and cells are tiny‚ hard‚ tooth like structure that makes the skin tough like sandpaper for protection. Their inner organs are much like that of a human. They contain the stomach‚ spleen‚ pancreas‚ rectum and the

Energy in an utilizable form is something essential for the functioning of any organism. Mitochondria and Chloroplasts are the two primary organelles in eukaryotic cells that involve in the transformation of energy‚ thus in production and consumption respectively. The chloroplast is an organelle present only in plant cells and some prokaryotes. At the same time they are absent in animal cells. It’s through the chloroplast that entry of energy to a cell takes place where sunlight is used to trap

Julia Babin Ms. Bukola 11/6/2012 Bio Lab W 8 Cell Structure and Function Prokaryotic cells do not contain a nucleus. Eukaryotic cells do contain a nucleus. Organisms are eukaryotic except Bacteria and Achaea. Organelles are small membranous bodies‚ each with a specific structure and function. Prokaryotes do have cytoplasm‚ which is the material bounded by a plasma membrane and cell wall. This contains ribosomes‚ small granules that coordinate the synthesis of proteins

Lipids are made up of carbon‚ hydrogen and oxygen (phospholipids also contain phosphate) and are found in a wide variety of organisms from bacteria to eukaryotes where they perform a wide variety of useful functions. This essay will expand on these functions to describe the role of lipids. There are several types of lipid including triglycerides‚ steroids‚ waxes and phospholipids. Triglycerides are made up of three fatty acids combined with glycerol by an ester linkage meaning they are predominantly

Chapter 3 Cell Structure and Function Section 3.1: Cell Theory: Cells are the smallest building unit of living organisms that can carry out all processes required for life. Almost all cells are too small to see without the aid of a Microscope. Although glass lenses used to magnify images for hundreds of years‚ they were not enough to reveal individual cells. The invention of Compound microscope was in the late 1500s by the Dutch eyeglass maker Zacharias Janssen. In 1665‚ the English scientist

Located in South America‚ the Amazon rainforest covers a span of about 3.5 million square miles in several different countries‚ making it the world’s largest rainforest. Rainforests are characterized by the heavy rainfall they receive which is a minimum of six and a half feet a year. Also‚ they can either be tropical or temperate‚ and they are found on nearly every continent‚ not including Antarctica. They are also composed of several vertical layers. The canopy‚ the uppermost layer‚ is the “tops

Chapter 2 Integrin Structure and Function Manakan Betsy Srichai and Roy Zent Abstract Integrins are a large family of heterodimeric glycoprotein receptors first discovered over twenty years ago. They exist as two noncovalently bound a- and b- subunits that function as adhesion molecules and play key roles in many biological processes including actin cytoskeleton organization and transduction of intracellular signals regulating cellular functions. Integrins bind a variety of extracellular matrices
