regions of membrane lipids involved in cell signaling are called lipid rafts. • Hopanoids are sterol-like molecules found exclusively in bacteria. • Membranes from cells grown in media enriched with stearate are less fluid than normal membranes. This is because the membranes have more saturated fatty acids. • The functions of the biological membrane are : • They contain receptors for the detection of external signals • They provide a means of cell to cell communication • They regulate movement

Plant cells are eukaryotic cells that differ in several key aspects from the cells of other eukaryotic organisms. Their distinctive features include: A large central vacuole‚ a water-filled volume enclosed by a membrane known as the tonoplast maintains the cell’s turgor‚ controls movement of molecules between the cytosol and sap‚ stores useful material and digests waste proteins and organelles. A cell wall composed of cellulose and hemicellulose‚ pectin and in many cases lignin‚ is secreted by

develop a manufacturing cell? Support your answer with examples. Cellular manufacturing is a manufacturing process that produces families of parts within a single line or cell of machines operated by machinists who work only within the line or cell. A cell is a small scale‚ clearly-stated production unit within a larger factory. This unit has full responsibility for producing a family of like parts or a product. All necessary machines and manpower are enclosed within this cell‚ thus giving it a level

A solar cell (also called photovoltaic cell or photoelectric cell) is a solid state electrical device that converts the energy of light directly into electricity by the photovoltaic effect. Assemblies of cells used to make solar modules which are used to capture energy from sunlight‚ are known as solar panels. The energy generated from these solar modules‚ referred to as solar power‚ is an example of solar energy. Photovoltaics is the field of technology and research related to the practical

Urban Transport Project Abstract London is a busy city with many people wanting to get to a destination. London transport gets commuters and tourists moving from one place to the next‚ with a choice of buses and tube. The Tube is probably the best form of transport in London in terms of coverage‚ speed and reliability. However London buses are also great as they don’t get stuck in traffic due to buses having their own bus lanes. This report shows the quality of London’s public transport addressed
