Describe the key structures and functions of a eukaryotic and prokaryotic cell. Eukaryotic Cell (1) There are many organelles in the eukaryotic cell micrograph above. Some of these organelles are displayed in the prokaryotic micrograph and so‚ I have described the shared organelles in the prokaryotic micrograph section. Mitochondria The mitochondria cells break down nutrients which then creates energy. They act like a digestive system. This process is called cellular respiration. The

Stem cells are probably the most important scientific discovery.These are pluripotent cells current in all living organısms.These cells have infınitive divisibility and self renewal properties‚ and also has the ability to convert organs and tissues.Human life in the form of a sperm‚ovum‚embryo‚fetus‚newborn‚child‚youth and adult.Therefore‚human can face to face with cancer‚alzheimer‚burns‚diabets‚heartdisease‚parkinson etc.To find the solution to that all problems stem cell treatment is inescapable

Transport in Plants Matthew H. 9A 131002 Today I will be discussing our experiment and the basics of transport of minerals and water in plants. Transport in plants are called transpiration. Water evaporates from the leaves which cause a type of suction that draws water from the roots. The water travels up via the vascular bundles. This flow of water is called transpiration stream. Some pressure is created forcing some water out of the cells in into the spaces between the cells

Transport and the environment The chapter examines how transport affects the environment; how its impact can be quantified in economic terms; and how economic incentives can be used to reduce the environmental cost of transport‚ as well as addressing other externalities associated particularly with car use‚ such as congestion. The environmental impacts of transport “Transportation services are essential component of economic activity‚ and are one key to its growth. Transportation has a number

A mechanism is generally defined as any object or system that has a working part or parts. Most often the term suggests tools‚ instruments‚ and machines. But other examples of mechanisms could be the human body and systems like the universe or a city‚ which is composed of parts that work together like parts of a machine. A technical man constantly works with mechanisms and always needs to understand them; what they do‚ what they look like‚ what parts they have‚ and how these parts work together.
