(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

oxidized and thus causes reduction ELECTROCHEMISTRY INVOLVES TWO MAIN TYPES OF PROCESSES: A. Galvanic (voltaic) cells – which are spontaneous chemical reactions (battery) B. Electrolytic cells – which are non-spontaneous and require external e− source (DC power source) C. BOTH of these fit into the category entitled Electrochemical cells GALVANIC CELLS Parts of the voltaic or galvanic cell: o Anode--the electrode where oxidation occurs. After a period of time‚ the anode may appear to become smaller

Background Information: Cell Transport When molecules move from a high to low concentration it is called moving DOWN the concentration gradient. When molecules move from a low to high concentration it is called moving AGAINST the concentration gradient. When the concentration of a solute is the same throughout a system‚ the system is at EQUILIBRIUM. What kind of transport DOES NOT require energy? PASSIVE What kind of transport requires energy? ACTIVE Which CELL PART provides the energy for

The principles of John Von Neumann Model using a block diagram. John von Neumann Block Diagram John von Neumann Block Diagram John von Neumann is known as “The Father of the Computer” or subsequently as the “von Neumann architecture”. The main principles of John von Neumann were he devised a concept for computer architecture that remains with us to this day‚ the stored-program concept. The computer should operate completely electronically. An electronic stored-program computer where both

Blood Cells Leukocytes (WBC’s) Leukocytes also known as white blood cells (WBCs) are cells which play a defensive roll in the body against injury and infection. They migrate towards tissues where they are needed and become functional performing various activities. WBCs can be divided into 2 groups: Polymorphonuclear granulocytes and mononuclear agranulocytes. Both types are spherical while suspended in blood plasma but when they invade tissues after leaving the blood vessels they become amoeboid

Chapter 2 METHODOLOGY This chapter discusses the methodology‚ the data gathering techniques‚ and the scope and delimitation of the study. This will serve as the guide to the proponents on how they will conduct the study systematically in order to fulfill the study’s objectives. Software Development and Methodology The Rapid Application Development (RAD) approach would be used to develop the system because of time constraints in the development schedule. RAD is a linear sequential software
