BTEC Lv. 2 in Health and Social Care Unit 5: Anatomy and Physiology for Health and Social Care Task 1: P1: Outline the functions of the main cell components P2: Outline the structure of the main tissues of the body P3: Outline the gross structure of all the main body systems. Cell (or plasma) membrane The electron microscope shows the cell membrane to be a phosphor-lipid-protein-bi-layer. Small‚ fatty molecules in bi-layers are the lipids. Larger protein molecules are inserted at intervals

reservoir in a city. Another one is the nucleus‚ it’s a large organelle found in most cells except bacterial cells its job is to control all cell functions‚ it’s the head of the cell also like city hall or the mayor. In addition the Golgi Bodies or Golgi Apparatus modifies‚ stores‚ and directs the movement of molecules made by ER (Endoplasmic Reticulum) in the same way the mail delivery does in a city. Lastly‚ is the mitochondrion which transforms the unusable energy in food molecules into a form

There are two types of cell transport mechanisms. These types of transports are passive and active transport. The difference between active and passive is that passive does not require energy and active does require energy. The reason passive does not require energy is because it travels down a concentration gradient. On a concentration gradient molecules naturally move from high to low concentration. In active transport‚ molecules move from low to high concentration. There are three different types

CODE-Y NEET-UG – 2013 TEST PAPER WITH ANSWER (HELD ON SUNDAY 05th MAY‚ 2013) 1. The eye of octopus and eye of cat show different patterns of structure‚ yet they perform similar function. This is an example of : (1) Analogous organs that have evolved due to divergent evolution (2) Homologous organs that have evolved due to convergent evolution (3) Homologous organs that have evolved due to divergent evolution (4) Analogous organs that have evolved due to convergent evolution (4) Select the correct

performs in order for the cell to function and maintains the cell membrane. The main components of the cell include the cell membrane‚ cytoplasm‚ the nucleus‚ nucleolus‚ nuclear membrane‚ endoplasmic reticulum (smooth ER and rough ER)‚ mitochondria‚ Golgi apparatus‚ lysosomes‚ ribosomes and vacuoles. a) The cell membrane – The cell membrane otherwise known as the plasma membrane is located on the surface of a typical animal cell. The cell membrane is made up of a phospholipid bilayer and is a selectively
