Observing Osmosis in Potato Cells Planning Purpose: To observe the effect of osmosis on plant cells. Hypothesis: The higher the salt content of the water‚ the lower the mass of the potato. Variables: Independent: the salt percentage of the solution Dependent: the weight of the potato in grams Controlled: the amount of water the length of time between measurements the method of measuring the type of plant cells tested Equipment: (as seen on 2A Human Biology task sheet)

Lindsay Turner 4/20/01 White Blood Cells Bacteria exist everywhere in the environment and have continuous access to the body through the mouth‚ nose and pores of skin. Further more‚ many cells age and die daily and their remains must be removed‚ this is where the white blood cell plays its role. According to this quotation‚ without white blood cells‚ also known as leukocytes‚ we would not be able to survive. White blood cells are our body ’s number one defense against infections. They

White blood cell (WBC)—A white blood cell is one of the three main types of blood cells. They are produced in the bone marrow and released into the blood. White blood cells are responsible for fighting infection. There are several kinds of white blood cells‚ including monocytes‚ lymphocytes‚ neutrophils‚ eosinophils‚ and basophils. White blood cells‚ or leukocytes (also spelled "leucocytes"; from the Greek word leuko- meaning "white")‚ are cells of the immune system involved in defending the body

treatment of Thalassemia. WHAT IS THALASSEMIA? Thalassemia is genetic disorders that involve the decreased and defective production of hemoglobin‚ a molecule found inside all red blood cells (RBCs) that transports oxygen throughout the body (Miller‚ Thalassemias‚ 2008). As (Hashemi‚ 2011) says "Thalassemia is blood disorders ". As (Clinaero‚ n.d.) says" There are mild and severe forms of the disorder as well. Severe Thalassemia is often called Cooley’s anemia". There are two main types of Thalassemia

membrane is a special case of diffusion known as osmosis. Osmosis results in the movement of water from an area of lower concentration of dissolved material to an area of higher concentration of dissolved material. For a demonstration of this principle‚ a purple onion cell is going to be bathed in different concentrations of salt (NaCl) water. Problem: How do solutions of various salt concentrations influence osmosis in relation to an onion cell?

muscle movement and certain cell reactions are reliant on energy the transport of oxygen to the cells of tissues and organs by blood vessels is vital for respiration to occur. Oxygen is carried in red blood cells by the pigment haemoglobin‚ a globular protein consisting of four polypeptide chains. Both of these components of blood are structured specifically to carry out their functions of oxygen transport‚ hence ensuring efficient respiration. Erythrocytes‚ or red blood cells‚ possess a unique structure
