    857 Words  | 4 Pages

    Cell organelles are small structures within cells which carry out specialised functions and they have structures which are heavily adapted to their function. Firstly, chloroplast is a cell organelle that is commonly found in plant cells such as palisade cells and it has a unique structure which is fundamental in carrying out its function. Chloroplast is the site of photosynthesis; it carries out the light dependent reaction and the light independent reaction of photosynthesis and its structure is

    The process of homogenization disrupts the cell tissue in order to release the contents of the cells into the homogenate. Once the organelles have been released into the homogenate they are isolated by centrifugation. This process is effective due to the fact that different cellular structures move through the homogenate differently, based mostly on size and density. Therefore, different centrifugal forces and times are used, specific to which organelle or cellular component you are trying to isolate

    Cells are easy to distinguish by their shape. How are the shapes of cells related to their functions? Cells are the basic unit of a living organism. They are the smallest independently functioning unit in the structure of an organism, usually consisting of one or more nuclei surrounded by cytoplasm and enclosed by a membrane. The shape of a cell is related to its function because of the adaptations made throughout time to make the cell as efficient as it can be. There are two types of cells
