    The cell wall is the tough‚ flexible but sometimes fairly rigid layer that surrounds some types of cells. It is located outside the cell membrane and provides these cells with structural support and protection. Just as the wall of the factory is for the factory. The wall also is the structure and strength. The cell membrane that separates the interior of all cells from the outside The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances

    M2 needs to discuss different tissue types to achieve D2. In this essay I will include information regarding: cell differentiation‚ the functions of various cell organelles‚ tissues and a comparison of different tissue types. Cellular differentiation is the process by which a less specialised cell becomes a more specialised cell type. Differentiation happens a number of times during the development of a multicellular organism as the organism changes from a fertilised egg cell to a complex system

    Each cell can be regarded as a metabolic compartment‚ as separate place where the chemical processes of that cell occur‚ the cell is made up of different organelles each specifically designed to carry out their function‚ and this is known as a cells ultrastrucure. All cells have a cell surface membrane; these are made up of phospholipids and make up a bilayer. A phospholipid has a hydrophilic head and a hydrophobic tail which is made up of 2 fatty acid chains; these are arranged is two layers with

    Polymers have different structures. They also have different functions. Describe how the structures of different polymers relate to their function? Polymers a large molecules made up of a chain of smaller molecules‚ known as monomers. The monomers that a polymer is made up of decide its structure and therefore it’s function. These monomers are linked and coiled in a very specific manor giving the polymer a specific tertiary structure (an extensively coiled and linked polymer chain caused as a

    Functions of the cells The functions of cells are shown in the body which is comprised entirely of cells. Every cell also has its own or more than one job to do. The cell membrane The cell membrane also known as the - plasma membrane. It consist of two layers of a fatty type substance. Its function is to protect the inside and the outside of the cell by allowing certain substances into the cell‚ while keeping other substances out. It also serves as a base of attachment for the cytoskeleton in some
