Movement in and out of cells Diffusion: (mixing molecules) Molecules and ions in a liquid or a gas move continuously. The movement is quite random‚ and the particles change direction as they bump into one another. The particles collide more often when they are close together (when they are concentrated) and so they tend to diffuse‚ or spread out‚ until they are spaced evenly throughout the gas or liquid. The random movement of particles is due to their own kinetic energy. When the diffusion

Cells must move materials through membranes and throughout cytoplasm in order to maintain homoeostasis. The movement is regulated because cellular membranes‚ including the plasma and organelle membranes‚ are selectively permeable[1]. The purpose of an automatic flow of molecules is to create equilibrium on each side of the membrane. In order for molecules to pass through the membranes‚ there must be pores. The size of the pore determines what molecules can cross. Due to the size and polarity‚ only

Cells and Movement of Substances All living things are formed by cells‚ the structure of these cells varying depending on their function. Animal and plant cells have common features such as a nucleus‚ cytoplasm and cell membrane. Dissolved substances pass into and out of cells by diffusion Diffusion Diffusion definition: Diffusion is the movement of molecules from a high concentration to a low concentration. Dissolved

Discuss the movement (of substances) inside cells Substances can travel from inside the cell out and from outside of the cell inwards across a membrane. Movement of substances also occurs inside the cell and is part of many of the processes that occur inside cells in both eukaryotic and prokaryotic cells as well as animal and plant cells. The movement of substances may occur across a semi-permeable membrane such as the phospholipid bilayer membrane on the outside of a cell in the digestive

Osmosis Investigation We are trying to find out what the concentration of the solutions is inside the vacuole of a potato cell. We will investigate how the mass of the potato chips change in different sucrose solution concentrations. We will use osmosis to do this. I will be measuring and controlling many different variables‚ these include; - The dependent Variable Weight of potato chip Independent Variable Concentration of sucrose Control Variables consist of; - 1.

director of Inside Job‚ the progressive deregulation of the financial sector since the 1980s gave rise to an increasingly criminal industry. In fact‚ many executives and leaders that were involved in this meltdown refused to answer questions‚ and some refused to interview for the documentary all together.

Rahul Deorah 61310445 BRMT_B Intel Inside Intel devised a successful marketing strategy in 1988 for its 386 processor – the Red X campaign. By the time the product started taking off in‚ it was already technologically obsolete. In the rapidly evolving technological market‚ it was impossible to brand and run a successful new campaign for each new product innovation. Intel also had to find a way to be distinctive in an almost commodity like marketplace. The erstwhile head of marketing of Intel
