How do lysosomes help animal cells to function properly?
396642
lysosomes are storage sacs which containe enzymes to kill off foreign bacteria.  They also extact waste from the cell wall through exocytosis.  Lysosmes are called suicide sacs because of how they kill off the bacteria.  The lysosome will engulf the invading bacteria and let the enzymes go off inside of the cell killing both the cell and the bacteria.  Lysosomes are found in white blood cells.  They also help inthe digestion of food and molecule particles needed for cellular respiration.

When water enters the cell..it must be regulated or the cell will...em...explode...these vacuoles help the paramecium to send out extra water...

Each cell is like a plastic bag filled with a spaghetti soup of all the different cell components. But it's a very special plastic bag, because it is permeable - water and friendly chemicals can pass through it, but bad guys get shut out. Rather like the firewall works (or should work!) when you're on the internet. The cell membrane is the plastic of the bag.\n\n:-)\nDC\nwww.tigerworld.tv

the functions are:\nmRNA: Carries information and goest to ribosomes\ntRNA: Goes to the cytoplassm and picks up the amino acids\nrRNA: Makes the ribosomes

Mitochondria in animal cells convert energy into forms the animal cell can use.  Chloroplasts in plant cells are necessary for photosynthesis, converting sunlight into energy the plant cell can use.

The Golgi apparatus or the Golgi body functions as a protein processing center.  Once proteins are synthesized in the endoplasmic reticulum some proteins must be modified, for example with carbohydrates.  \n\nOnce processed the proteins eventually are localized to the cell membrane, lysosomes, or outside the cell (e.g. digestive enzymes)

the paramecium gets rid of excess water through the contractile vacuole.  this regulates the amount of water in the body of the paramecium. \n\nSince the regulation of the amounts of water and minerals in the body is included under the term homeostasis, the contractile vacuole is said to help maintain homeostasis.

organelles perform a specific function for the cell (respiration, transportation, etc.) much like organs perform a specific function for an organism (circulation, respiration, etc.).  animal cells and plant cells have some organelles that are the same, but some are different (plants have cell walls and vacuoles, while most animal cells do not).

More importantly, large multicellular organisms have "specialized" cells. This means that if you took the average cell from the body it would simply die since most cells have outsourced various things to cells that can do it more efficiently. Blood for transporting oxygen, muscle cells for movement, etc.

Around the cell. It's what holds all the squishy bits in (cytoplasm etc.)

vacuoles r mainly used to store stuff. during phagocytosis for eg, they compartmentalise ingested material. If the cell wants to eat whatever they took in, the vacuoles will typically fuse with lysosomes, and the lysosome will break down whatever's inside the vacuole by using nasty acids at pH 1-2(sometimes, lysosomes r called suicide bags, because on occassion, lysosomes pop and spill its acid into the cell and kills it... but normally, it's thick membrane stops that from happenin... lol)\n\nYa, vacuoles can also be used to transport material around the cell. The Golgi apparatus, for eg, uses it to transport membrane proteins to the plasma membrane.\n\nHope this helps!

A phagocyte will engulf the bacteria, in the phagocyte, like a macrophage, there is a cell organell called a lysosome. In the lysosome are powerful hydrolytic enzymes. In the phagocyte the lysosomes fuse with the bacterial vesicle and the enzymes destroy the bacteria. This by the way does not work for the bacteria that causes TB.\na cell can produce a protein and exocytose the protein in a pinched off part of the plasma membrane called a vesicle.The final packaging of the protein is done by the golgi apparatus in the cell.\nActive transport is transport that uses energy. the energy source used is ATP produced by the mitochondria in the cell. A prime example of active transport is the sodium/potassium pump each living cell employs.

We have used the pH-dependent fluorochrome fluorescein-dextran (FD) to study the acidification of prelysosomal vacuoles (endosomes) and lysosomes isolated from cultured macrophages and fibroblasts. FD was internalized by pinocytosis under conditions that allowed its selective localization in endosomes (1- to 5-min pulse) or in lysosomes (5-min pulse, 30-min chase). Fibroblasts were also exposed to FD at 20 degrees C, at which temperature endosome-lysosome fusion is inhibited. Cells were homogenized and labeled organelles were separated by centrifugation in Percoll density gradients. The addition of ATP rapidly decreased the internal pH of both endosomes and lysosomes, as indicated by a decrease in fluorescence intensity. The pH gradient was dissipated by H+ ionophores and ammonium chloride. Acidification was not affected by inhibitors of the mitochondrial F1,F0-ATPase or the Na+, K, K+-ATPase and did not require permeant anions, Na+, or K+. Of the inhibitors tested, only N-ethylmaleimide prevented the ATP-dependent acidification of both compartments. These findings provide direct support for the existence of an acidic prelysosomal compartment that may be acidified via the same type of H+ pump believed to operate in lysosomes and secretory granules.

An animal cell is a form of eukaryotic cell which make up many tissues in animals. The animal cell is distinct from other eukaryotes, most notably plant cells, as they lack cell walls and chloroplasts, and they have smaller vacuoles. Due to the lack of a rigid cell wall, animal cells appear to be circular (though are often deformed by surrounding cells) under microscopes - in three dimensions the cells are normally spherical.

Very big cells usually can't survive because the ratio of their surface area to their volume is too small, and they can't get enough nutrients in and waste out. So maybe a faster method of exchanging substances with its environment? Sorry if I'm not much help.

In cell biology, a vesicle is a relatively small and enclosed compartment, separated from the cytosol by at least one lipid bilayer. If they have only one lipid bilayer, they are called unilamellar vesicles; otherwise they are called multilamellar. Vesicles store, transport, or digest cellular products and wastes.\n\nThis biomembrane enclosing the vesicle is the same as that of the outer cellular membrane. Then, because of the separation, the intravesicular environment can be made to be different from the cytosolic environment. Vesicles are a basic tool of the cell for organizing metabolism, transport, enzyme storage, as well as being chemical reaction chambers. Many vesicles are made in the Golgi apparatus, but also in the endoplasmic reticulum, or are made from parts of the plasma membrane.\n\nMore at http://en.wikipedia.org/wiki/Vesicle_%28biology%29

Lysosome has no color.  Those colors that you see in textbooks are just for illustration.  If you look at a cell under a microscope, you don't see any colors... they are usually transparent with dark shapes (vacuoles) which some are lysosomes, endosomes, ER, etc.\nLysosomes are vacuoles in the cell that contain lytic enzymes to break down bacteria, proteins, etc.  They do contain different cellular markers on their surface (ex. Lamp-1) where some functions are to acidify the lysosome and determine the trafficking in the cell.
