Cells are some of the smallest organisms around. All living things consist of cells‚ and yet they are invisible to the naked eye. Cells are the basic structural and functional units of life. Cells are made up of many different parts which allow them to function properly. All cells are separated from their surrounding by a cell membrane. The cell membrane regulates what enters and leaves the cell and also aids in the protection and support of the cell. A cell membrane

Cytoplasm Cell Membrane Nucelous Nuclear Envelope Nuclear Pore Lysosomes Microtubles Microtubules- Is a component of the cytoskeleton. Centriole- Aids in cell division and it’s only in animal cells. Lysosomes- Clean-up organelle it digests and breaks down lipids‚ carbs‚ and proteins. Nuclear Pore- Dots on the envelope which allows material in the and out of the nucleus. Cell Membrane- It surrounds the cell and regulates what enters and leaves the cell. It is selectively

10-8-09 Biology Essay: Parts of a Cell Describe the fluid-mosaic model of a plasma membrane. Discuss the role of the membrane in the movement of materials through each of the following processes: a.) Active Transport b.) Passive Transport All living cells contain a plasma membrane‚ which acts a boundary for the cell. The plasma membrane regulates the cell’s chemical composition because it uses selective permeability to allow certain substances to enter or exit the cell more easily than others

B cells belong to a group of white blood cells known as lymphocytes‚ making them a vital part of the immune system The human body makes millions of different types of B cells each day that circulate in the blood and lymphatic system performing the role of immune surveillance. They do not produce antibodiesuntil they become fully activated. Each B cell has a unique receptor protein (referred to as the B cell receptor (BCR)) on its surface that will bind to one particular antigen. If the pathogens are

Cell Biology Oct.3/14 Cell Cycle part 3: Apoptosis 2 Main ways cells will die: apoptosis is regulated‚ nacrosis is an “explosion” Apoptosis Part of controling number of cells. Importance in balance.“Programmed cell death” – important because if the cell isn’t intact you don’t want cell to divide and keep mutations going‚ to avoid inflammatory response (caused by cells that exploded/necrosis).. ect. Necrosis is triggered by something unplanned‚ leading to decrease ATP‚ pumps‚ atpase activity
