In a root these are arranged in the centre forming a structure called the stele. Xylem tissue has the dual functions of support and transport. It contains several different types of cells these are vessel elements‚ traceids‚ fibres and parenchyma cells. In contrast to this phloem tissue is living and comprises of sieve tubes‚ phloem

1: Ecosystems at Risk A. Ecosystems and Their Management 2. Vulnerability and Resilience of Ecosystems * Vunerability is the sensitivity of an ecosystem to cope with stress. * Resilience is the ability of an ecosystem (or a component of an ecosystem) to adapt to a changing environment and to restore function and structure following an episode of natural or human-induced stress. * All ecosystems function in a state of dynamic equilibrium or a continual state of balanced change. *

I. Describe the structure and function of the nucleus and mitochondria. The mitochondria is a semi-autonomous organelle which reproduces by bynary fission and has its own DNA. Its main function is to produce the energy intermediate ATP‚ through ATP synthase. Mitochondria could be considered a cell inside a cell. It has its own membranes (inner and outer membranes)‚ its ribosomes (to produce the proteins encoded in its DNA)‚ a matrix -- where aerobic respiration occurs. The invaginations of the inner

Ecosystems are systems through which incoming solar energy is captured and channelled through a hierarchy of life forms. Each ecosystem has its own characteristic plant and animal community. Nature of change refers to the natural or human induced change towards an ecosystem. Humans

“The structures of body systems are determined by their functions”. Discuss this statement‚ focussing on the Circulatory System. You should include diagrams and relevant examples in your essay. In order to survive it is necessary for every cell in the body to exchange materials as not all cells are in contact with the external environment; we rely on the circulatory system to do this which is composed of the heart‚ blood vessels and blood. The heart consists of four chambers two atria and two ventricles
