Three types of passive transport are osmosis, diffusion, and facilitated diffusion. Osmosis in red cells placed in a hypertonic solution Now think what would happen if red blood cells were placed in a salt solution that has a higher salt concentration than the solution within the cells see diagram 3.
The DNA does not hang around loosely in the nucleus. The two types of ER make different building blocks for the cell. It is a completely passive process and requires no energy. Most cells carry out pinocytosis note the pinocytotic vesicle in diagram 3.
The nucleus controls the development and activity of the cell. Pores in this nuclear membrane allow communication between the nucleus and the cytoplasm.
Larger molecules like glucose attach to a carrier molecule that aids their diffusion through the membrane. Summary[ edit ] Cells consist of three parts: Osmosis is also important in the production of concentrated urine by the kidney.
The function of the Rough ER is therefore to make proteins that are modified stored and transported by the ER Diagram 3. June 1, 0 Comments Epithelial Tissue Epithelial tissue is a sheet of cells that covers a body surface or lines a body cavity. Disseminated intravascular coagulation DIC: An abnormally low number of red blood cells in the blood.
These molecules include proteins, fats and carbohydrates as well as sodium, potassium, calcium and chloride ions. It shows a container divided into two parts by an artificial semi-permeable membrane. Most cells are spherical or cube shaped but some are a range of different shapes see diagram 3.
It takes place because all molecules have an in-built vibration that causes them to move and collide until they are evenly distributed.Anatomy and Physiology of the Male Reproductive System the process of cellular differentiation leads cells to assume their final morphology and physiology.
Differentiation is the process by which unspecialized cells become specialized to carry out distinct functions.
