What are contractile vacuoles in paramoecium?
609978
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...

Here is what i could fined but i was unable to find anything on the leaf eperdemal cells.\n\nA red blood cell is - a cell in the blood of vertebrates that transports oxygen and carbon dioxide to and from the tissues\n\nprotozoans - Any of a large group of single-celled, usually microscopic, eukaryotic organisms, such as amoebas, ciliates, flagellates, and sporozoans.\n\nPhloem - the part of a vascular bundle consisting of sieve tubes, companion cells, parenchyma, and fibers and forming the food-conducting tissue of a plant. \n\nMuscle cells - an elongated contractile cell that forms the muscles of the body\n\n Xylem -a compound tissue in vascular plants that helps provide support and that conducts water and nutrients upward from the roots, consisting of tracheids, vessels, parenchyma cells, and woody fibers.

ok, so generally speaking, in the hypotonic environment, a cell is swell up, and potentially burst. The way to remember this is that hypO (the letter O)tonic is the cell which is normally drawn as a more squarelike shape becomes circular as it takes on water. In an isotonic solution, the environment and the cell have equal solutes so no movement of water occurs. In a hypertonic solution (lots of particles in the environment) so the water leaves the cell and shrivels up. \nHowever, we also have to take into account the type of cell that we are placing into these environments. The above applies to animal cells and paramecium as they don't have rigid cell walls. However, plant cells do have cell walls so it does not apply to them. Plant cells have what we call turgor pressor, so they can withstand the environmental influences, or changes in tonicity, alot better. When the plant takes on water, it has the cell wall to prevent bursting. When the plant cell looses water, the cytoplasm shrinks while the cell wall keeps the cell's shape.\n\nQuestion 2:\nIf you were to place elodea or paramecium from fresh to salt water:\nwhen elodea is placed in salt water, we observe the process of plasmolysis - shrinkage of cell contents due to water loss.\nfor image see:\nhttp://images.apple.com/education/solutions/iwork/lessons/media/RealWorldScienceSample.pdf\n\nWith Paramecium: it has 2 contratile vacuoles that are used to balance salt concentration by expelling water

protozoa are single cellular organisms thus they do not possess systems they have cell organells to perform different functions . in protozoa food is circulated with the help of vacuole

all plant life have rectangle shaped cells

"Phylum Ciliophora:...A unique feature of all ciliates is the presence of two nuclei. The macronucleus  controls the cells growth and contains hundreds of copies of DNA. The micronucleus  is a small diploid nucleus used during the process of conjugation when genetic material between paramecia is swapped."\n\nThere are others out there, especially funguses that have multiple nuclei, but this seemed the most likely to be the one you were looking for.

Almost all cells reproduce like amoeba. There are very, very few that do not.\n\nSo take your pick. Turkey stomach cells reproduce like amoeba, pine needle cells reproduce like amoeba, human lung cells reproduce like amoeba.

They are plant-like protists with two flagella to move. The move in a corkscrew like manner

The amoeba heads toward the unsuspecting paramecium It begins to spread out it's body to catch its prey Too late for the paramecium,it's been caught The amoeba spreads out even more to surround its lunch This microbe starts to look like a big mitten! The amoeba keeps changing its shape \nuntil it can enclose its prey The paramecium will soon be \ncompletely inside the amoeba The amoeba will absorb its lunch directly inside its cell walls

Protoplasm can only be as high as the water meniscus pressure. I suppose it could be very large diameter, but not very thick. The cell is feed through osmosis from the arteries. I suppose with more capillaries feeding it there is no limit metabolically. If amoebas could not reproduce, fission, then would they get very big?

The non-living cell wall surrounds the living protoplast. Within the cell wall the cell membrane encloses the cytoplasm containing organelles (chloroplasts, mitochondria, nucleus, etc.) and a vacuole.\nThe vacuole contains many chemicals dissolved in water. Osmotic pressure within the vacuole squashes the cytoplasm against the cell wall when the cell is turgid to provide shape and support.\nThe two major compartments of the living part of a plant cell are the cytoplasm and the vacuole.

Meristem\nFrom Wikipedia, the free encyclopedia\nJump to: navigation, search\n\nA meristem is a tissue in plants consisting of undifferentiated cells (meristematic cells) and found in zones of the plant where growth can take place - the roots and shoots.\n\nDifferentiated plant cells generally cannot divide or produce cells of a different type. Therefore, cell division in the meristem is required to provide new cells for expansion and differentiation of tissues and initiation of new organs, providing the basic structure of the plant body.\n\nMeristematic cells are analogous in function to stem cells in animals, are incompletely or not at all differentiated, and are capable of continued cellular division (youthful). Furthermore, the cells are small and protoplasm fills the cell completely. The vacuoles are extremely small. The cytoplasm does not contain differentiated plastids (chloroplasts or chromoplasts), although they are present in rudimentary form (proplastids). Meristematic cells are packed closely together without intercellular cavities. The cell wall is a very thin primary cell wall.\n\n                                       ***\n\nThe answer is definitely meristems. Endodermis is the outer layer of a leaf, parenchyma are the dividing cells that usually make up meristems and most soft parts of the plant, while protonema are green filaments on moss.

you have microtubules, microfilaments, intermediate filements and microtrabecular system. these are vastly different from each other. do you have any more specific question?

OK, what would you like to know, how to feed a paramecium or how it eats?\nIn any case, here is a great link that should help you find out EVERYTHING you did or did not want to know about them :-) They really are fascinating creatures!!\n\nhttp://www.101science.com/paramecium.htm

Plants have one large vacuole. Animals have many vacuoules. Plants have a cell wall and chloroplasts. Animanls have neither. Animals have centrioles. Plants do not. This is the complete list of the differences.
