[pic] Cells and Their Organelles The cell is the basic unit of life. The following is a glossary of animal cell terms. All cells are surrounded by a cell membrane. The cell membrane is semipermeable‚ allowing some substances to pass into the cell and blocking others. It is composed of a double layer of phospholipids and embedded proteins. Color and label the cell membrane tan. Plant cells have an additional layer surrounding them called the cell wall. The cell wall is made of nonliving

(Hint: those buried deep in the cell probably do different things than those closer to the cell membrane). Structure does not affect function of the cells‚ cells have a particular structure that enables them to carry out their function in the best way. 2. Draw a labeled diagram of a small section of the plasma membrane and briefly describe its structure and function. 3. Describe the difference between the animal and plant cells. Plant Cells have cell walls‚ which makes them appear rectangular

Cell Specialisation All cells are designed to perform a particular job within an organism‚ that is‚ to sustain life. Cells can become specialized to perform a particular function within an organism‚ usually as part of a larger tissue consisting of many of the same cells working together for example muscle cells. The cells combine together for a common purpose. All organisms will contain specialised cells. There are hundreds of types of specialised cells. Below is listed some of the major ones

which he called cells’ this in itself unbeknownst to him‚ was the discovery of the fundamental unit of all living things. In 1838 a botanist called Schleiden derived the theory The basic unit of structure and function of all living organisms is the cell.’ Over 150 years later this can be regarded as one of the most familiar and important facts within the biological fields.

Cell Fractionation * Cell Fractionation: takes cells apart and separates the major organelles and other subcellular structures from one another. * Tissue cells are the first one to be homogenate or broken apart. * Plasma membranes are broken up so that there internal contents spill out and mix together and this is called homogenate. * Homogenate is in spun in a higher rate of speed in a process called centrifugation. And that speed can vary that why it’s called differential
