Biology- cell organelles assignment Animal cells: Introduction: An animal cell is called a eukaryotic cell; it has a cell membrane‚ cytoplasm and a nucleus. The cell surface is covered by a membrane only. The cell membrane is strong and keeps the cell together even though it is thin and flexible. The cell membrane also controls what goes in and out of the cell e.g. nutrients go in and waste comes out. The cytoplasm is inside the nucleus and it controls the cells activities. An animal is

Process of Diffusion and its importance in living organisms Diffusion is the movement of molecules or ions down a concentration gradient i.e. from an area of high concentration to an area of low concentration. For a diffusion system to be efficient‚ it should have a large surface area so that high amount of substances can be exchanged at a time. It should also have a thin membrane and a continuous supply of substances‚ as a thin membrane means that the diffusion pathway would be short‚ and the continuous

AS Biology - Unit 1 ------------------------------------------------- Metabolism Metabolism is a term to describe all reaction which is taking place within a cell and is separated into two types which are * anabolic = compounds being built up * catabolic = compounds being broken down ------------------------------------------------- Water The water molecule is a molecule which is made up from 2 hydrogen atoms and 1 oxygen atom. It is bounded by 2 covalent bonds and has is polar.

An ecosystem is a biological environment consisting of all the organisms living in a particular area‚ as well as all the nonliving or abiotic‚ physical components of the environment with which the organisms interact‚ such as air‚ soil‚ water and sunlight. In a typical ecosystem‚ plants and other photosynthetic organisms are the producers that provide the food. (Leibold) Ecosystems can be permanent or temporary and they usually form a number of food webs. Examples of ecosystem include: Marine Ecosystems:
