what happens when the plasma membrane of cell gets damaged?

1. The cells (and their organelles like mitochondria) swell (because the ability of the plasma membrane to control the passage of ions and water is disrupted).\n\n2. The cell contents leak out, leading to inflammation of surrounding tissues.

free radicals are basically rogue particles that bounce around inside your cells, damaging your cells as they go.  This causes your cells to deteriorate over time, which in effect is the aging process.  Theoretically, eliminating some of them slows the damage rate, and the aging process as well.

first off, it's Homeostasis.\n\nThe other guy is right, a cell is never at perfect equilibrium, however, on the two extreme ends, a cell could Lise (explode) with too much water(hypertonic to it's environment, so water enters the cell), or sort of shrivel up with not enough water (hypotonic to it's environment, so water leaves the cell)

The reason plasm exisits in all living things is because all living things are made up of cells, which have organelles (eukaryotic cells) and these organelles are suspended in an plasma such as cytoplasm. Without plasma these organelles would not be able to survive and function and therefore the cell would die and therefore the organism (animal) would die.

Your brain is mostly damaged in the part where a certain part of the spinal cord is damaged. Neurons do not regenerate. They get killed and don't come back. Nerve cells don't normally regenerate themselves.

As the radioactive elements decay, they emit high-energy particles that go crashing through the cell(s). These particles hit atoms within the cell, creating either ions that go on to damage the cell's DNA, or they hit and directly damage the DNA. Once their DNA is damaged, cells usually either repair the damage, or if they can't, commit suicide (called apoptosis). Only those cells that have been damaged and fail to repair it and fail to commit suicide can become cancerous. Of course, the final requirement is that the DNA is damaged in an area that controls cell replication is such a way as to allow the unchecked proliferation of the cell.

It binds to the sterols in the cells membranes and make them insoluble.  Without the sterols, the cells are much less fluid and more crystalline.  Sterols like cholesterol get a bad rap but they are very necessary!

Your body runs at a certain temp...when it gets too hot, cells get damaged.......just like a car that get over heated and things break down.

Keep in mind that necrosis is different from cell apoptosis.  \n\nApoptosis is "programmed cell death" where the cell actually will undergo extra protein synthesis in order to make the proteins for a rather organized cell death.  The cell essentially becomes a bunch of little vesicles that are eaten up by nearby phagocytic cells.  \n\nNecrosis occurs when the cell kinda falls apart.  It realeases a whole bunch of "crud" into the system that results in inflammation.  \nThere are whole protein cascades and signalling pathways that control these events.  But, in an overview, necrosis occurs in two general steps.  \n\n1. Chromatin clump up, and organelles begin to swell up.\n2. Plasma membrane breaks down, and the cell disintigrates.  The resulting debris can cause inflammation.

You're probably referring to the plasma membrane. The interior is hydrophobic, while the exterior is hydrophillic. The phospholipids can translocate horizontally within the bilayer, but can't cross from one layer to the other. So, the membrane behaves like a fluid.  See MIT's website for more info. the link is below

Ligaments are the stringy, strong "ropes" that attach the muscle to the bone.  \n\nI don't know what happens when they are damaged.  Sounds painful if they are damaged.

My best guess would be that the chloroplast would be marked as \n"non-self" in the cell and would be degraded in the lysosome. It would be might complicated to keep the chloroplast from being degraded.

Protein along with lipids form a lipoproteinous wall that surrounds the cell which is called plasma-membrane.for details got to below given link:\nhttp://en.wikipedia.org/wiki/Plasma_membrane

The cell membrane is made up of a phospholipid bilayer, with a polar phophate head and a nonpolar lipid tail. The polar head is hydrophilic, the nonpolar tail is hydrophobic. A fat molecule will face toward the nonpolar, hydrophobic tail.

Cells of the immune system more specifically B cells produce antibodies with shapes similar to the receptors on the foreign cells. Therefore these antibodies fit into the receptor sites on the membrane of the foreign cell and causes its membrane to break down.

(scroll to ">>>>>>")\nFor every cell, there is a time to live and a time to die. \nThere are two ways in which cells die: \nThey are killed by injurious agents. \nThey are induced to commit suicide.\nDeath by injury\nCells that are damaged by injury, such as by \nmechanical damage \nexposure to toxic chemicals\nundergo a characteristic series of changes: \nThey (and their organelles like mitochondria) swell (because the ability of the plasma membrane to control the passage of ions and water is disrupted). \nThe cell contents leak out, leading to \ninflammation of surrounding tissues.\nDeath by suicide\nCells that are induced to commit suicide: \nshrink; \ndevelop bubble-like blebs on their surface; \nhave the chromatin (DNA and protein) in their nucleus degraded; \nhave their mitochondria break down with the release of cytochrome c; \nbreak into small, membrane-wrapped, fragments. \nThe phospholipid phosphatidylserine, which is normally hidden within the plasma membrane, is exposed on the surface. \nThis is bound by receptors on phagocytic cells like macrophages and dendritic cells which then engulf the cell fragments. \nThe phagocytic cells secrete cytokines that inhibit inflammation (e.g., IL-10 and TGF-β)\nThe pattern of events in death by suicide is so orderly that the process is often called programmed cell death or PCD. The cellular machinery of programmed cell death turns out to be as intrinsic to the cell as, say, mitosis. \n\nProgrammed cell death is also called apoptosis.\n\n1. Programmed cell death is as needed for proper development as mitosis is. \nExamples: \nThe resorption of the tadpole tail at the time of its metamorphosis into a frog occurs by apoptosis. \n>>>>>>>>The formation of the fingers and toes of the fetus requires the removal, by apoptosis, of the tissue between them. \nThe sloughing off of the inner lining of the uterus (the endometrium) at the start of menstruation occurs by apoptosis. \nThe formation of the proper connections (synapses) between neurons in the brain requires that surplus cells be eliminated by apoptosis
