this is a question a student asked me,he has just finished making a model of a plant cell and needs to know how many uses it have and what are the uses

They're talking about the plant cell model...not the actual plant cells.

When I was in 9th grade we did a plant project. I bought two small plants that were the same. One of the plants I left it in the sun watered it everyday and took good care of it. The other we put it in a dark place and also watered it everyday and also took good care of it. I did it for two weeks. Everyday I would make an observation of the lenght of the plant and the leaves it dropped and wrote it down. Then on a posterboard I did 4 large graphs. Two of the graphs were the length it grew each day for each plant. And the other two I graphed how many leaves would fall out of each plant. And when I presented it in front of the class I brought both plants and my conclusion of the project was the affect the sunlight has on a plant. It really hopes that works. By the way I got an A+ on it.

First, the cell wall's function is to protect the plant cell.\nCell membrane - protects inner components of the cell from the outer environment. The rest are describe in the following website which you can go to.

YOU can co relate krants anatomy(presence of chloroplasts in bundle sheath cells) and high yield of starches in rice plant It needs some research on Internet .But otherwise it is a good topic for any seminars

well theres alot of material i can provide you with but i dont know what particular experiment you are designing as there are always different experiments within an experiment.\nanyhow, i think this is an example of an experiment for photosynthesis and respiration and their pH levels.\n\nhttp://www.science.siu.edu/plant-biology/plb337/old_st_papers/emmert.pdf \n\n\nif you are doing the same experiment, i guess you will find this one really helpful.\n\n.. Good Luck

How much time do you have?  If you have a few weeks....\n\nGet 5 of the same type of plant.\n\nMake sure they all have the same conditions.  Same type of soil/amount   Same amount of light/temp.  If using lamps, make sure they get the same amount of lamp time.\n\nThe goal is to keep all conditions the same aside from the one variable you will be testing... \n\nSo on to the variable.  Pick 5 different substances that you will give them for fluids... IE...\n\n1. Water  2. Soda   3. Bleach   4. Miracle grow or other plant food mixxed with water.   5. Orance juice.\n\nOkay.  Water will be your control group.  You will use this as a base line to compare all of the others to.  You can of course pick whatever you want for fluids. Those are just some ideas pick whatever fluids you want.  Always make sure to have a control group (the one with water) so you have something as a base line.\n\nGive them all 25 milliliters of the subtance each day. The amount you give them depends on what plant you pick, and its size, adjust accordingly. Make sure to feed them at the same time each day.\n\nBefore you start, write down your hypothesis.. \nHow do you think each plant will do? and why?\n\nTwice a week write down how the plants look.\nHow much they have grown.\nThe plants overall health.\nAlso, write down anything else you have noticed. i.e change in color, a plant dying.  \n\nThen compare it with the plant just getting plain water.  It is doing better than the control?  worse?  same? \n\nAt the end of each week make a theory on how you think the plant will do over the next week.\n\nMake sure to factor out all variable, and keep everything aside from the substance they get the exact same.\n\nWhen done with the experiment write a conclusion.  Was your hypothesis correct? What were you right about? What were you wrong about? How did each plant fair?  What could you have changed to make the experiment more accurate??  Did you do anytyhing wrong? ie mistakenly change something?  If you repeated the experiment, do you think the results would be the same? why or why not?\n\nMake sure to fully explain all of your statements. Charts or graphs of the results are always nice.\n\nThis would work the best if you started them from seed, but you prob don't have that kind of time span.  \n\nIf this is to childish of an experiment, maybe do a plant stem grafting experiment, or a cross-pollination between plants of the same species. i.e make a hybrid plant from 2 differnt types of tomatos or different flowers.

Cells are the little organisms that work together to make one big organism.  Your boddy has all kinds of different types of cells to do different things, like blood cells, nerve cells, etc.  Plants have root cells, leave cells (where the photosynthesis takes place, hence those are the cells with chloroplasts, which makes them do that function.)\nWhat's cools is that if you cut off a plants roots, it's cells for it's stem will become root cells and it's roots will grow back.  I don't think this works w/ peoplw/animals.  With people, a fetus's cells that have not been defined to a certain "task" yet will all do different things and can change to what they are needed for where they are as the fetus develops.  After it's defined, though, I don't animal/human cells can change as plant ones can, though.

This site lists some interesting science project ideas...\nyou can modify them to make them more or less complicated depending on your grade/age.\nhttp://school.discovery.com/sciencefaircentral/scifairstudio/ideas.html#plants\nGood luck on your project!

Use the pastel or whatever the kindergarden kids use.  It is like mud but comes in different colours.  The model should be a representation of the cross-section of your cell.  Use strings and other things to show different structures of the cell.  Some diagrams are drawn in 3D, and that's what your model should look like.  I wish they made us do that in university.  It would be fun.

Chromosones record genetic information. And aren't even organelles, they're part of the nucleus. ---> X\nNucleus ----> X\n\nMitochondria turn sugar into AtP (energy).\nChlorpasts store solar energy in the form of sugar.\n\nMitochondria function whenever oxygen is present and sugar is available.\nChloroplasts whenever CO2 and sun-light are available.

Hooooo.OK U want all explanation in yahoo answers?I Will try\n\nIN photosynthesis the sunlight energy is used by green plants to prepare food materials.\nn light reaction the sun light activates chlorophyll molecules so that they make NADDP2 and NADH2.These two in Calvin cycle reduce the co2+h2o in to glucose molecule\n\nIN respiration the reverse happens Of course in different steps\nGlucose molecule in respiration (it is a 6 carbon molecule6H12O6) passes through 3 phases to release the energy in the form of ATP(remember solar energy is taken in p.s to make glucose molecule)\n\nIn GLYCOLYSIS of respiration g;ucose divides in to two pyruvic acids which is aC3co,mpound (2X3=6CARBON glucose)\n\nIn KREBSCYCLE THE pyruvic acik(c3)com pound splits in to 3 co2 and while doing so , it producesNADPH2 nd NADH2\n\nINthe last phase the ELECTRON TRANSPORT  the reduced powers or NADH2 AND NADPH2  are oxidised  (at this stage it takes in oxygen_) in to energy(ATP)and co2\nso the end product in respiration is carbondioxide and energ y in the form of ATP

We did this in a lab I studied in in college.  You have to grow the cells in a stationary location with light.  Often they will differentiate on their own, but you may heve to use a root promoting auxin to get the plantlets to take root.  Once they do, you transfer them to a suitable growing mix and voila! you have a plant.\n\nIncidentally, we pioneered some work growing Niotiana tabaccum cells in suspension by continually agigtating them.  They will not differentiate if you do this.

Seperating cells from Morula to use them for medical purpose is technically feasible. But at present seperating such cells is not feasible. Some more research is needed.

The cells double every 12 hours.  In three days (ie 72hrs), the cells will go through 6 doublings (72/12=6).  \n\n0 hr = 2 cells\n12hr = 4 cells\n24hr= 8 cells\n36hr = 16 cells\n48hr = 32 cells\n60hr = 64 cells\n72hr = 128 cells\n\nThus you will have 128 cells after 3 days.
