B) It is a fluid mosaic model, with proteins interspaced in the phospholipids, both of which can freely move laterally.
Explanation:
The fluid mosaic model proposed by Singer and Nicolson describes the plasma membrane’s structure as a mosaic pattern of components consisting of phospholipids, proteins, cholesterol, and carbohydrates; all of which provides the unique fluid character of the membrane.
According to this model, the phospholipids constitute the main fabric, cholesterol attaches between the phospholipids in between the layers, integral proteins embedded within the bilayers of the phospholipids, peripheral proteins along the peripheries of the layers and carbohydrates outside the membranous layers.
Carbohydrates provide your body with energy. The simplest are sugars, like glucose, fructose, sucrose and lactose. Complex carbohydrates, like starch, are made up of lots of sugar molecules joined together. The 'identity tags' (antigens) on the surface of all cells are made from carbohydrates joined to proteins.
they are used in movement and as a tool to capture prey . in order to move using pseudopods , the organism pushes cytoplasm towards one end of the cell , which makes a projection , or pseudopod , off the cell. (sorry if i misspelled the word. )
