the diference between C3 and C4 plants?

I won't do your homework for you, but I will give you a few hints.\n\nThe first hint is that ddnight is talkin' smack. This has nothing to do with atmosoheric composition.\n\nThe second hint is that you should be looking very varefully at the relative effect of C4 and CAM utilisation on water LOSS. Underline the word 'loss".\n\n--------------------\n>>>CAM plants and C4's do better in higher temps than C3's.\n\nGenerally yes. But the question is why the plants died in that order. Begonia are tropical plants, so a temperature would not have killed it, and the pineapple is both tropical nad C4, sdo temperature effects can't be at play directly.\n\nOnly one plausible explanation remains.

Generally, monocots photosynthesize via the C4 pathway.  That means they have specialized internal framework called kranz anatomy to allow photosynthesis to occur.  It occurs in a different way then dicots so that their stomata dont need to stay open as long so they can conserve more water since monocots are typically found in dry climates.

Plant cells have Chloroplast... Cell Walls... and Water Vacuoles\n\nAnimals cells... of a centrioul, and food Vacoules.\n\nThose are the main differences of the organells

The plant kingdom, one of four eukaryotic kingdoms, is composed of multicellular, autotrophic organisms that photosynthesize to fix inorganic carbon (from atmospheric CO2) into organic molecules. Plants are the foundation of all terrestrial habitats, and serve as terrestrial Earth’s primary autotrophs, making organic molecules that will cycle through the food webs of most ecosystems. The photosynthetic capabilities of plants ultimately allow all terrestrial members of the animal kingdom to survive.\n\nOne hallmark of plant cells is the cell wall, which, in contrast to cell walls of single-celled organisms, is made of cellulose. The cell walls provide support for plant cells, as well as support and cohesiveness for plant tissue. Unlike the plasma membrane, the cell wall is not a semipermeable membrane, and so the shared cell walls between adjoining plant cells must have openings, plasmodesmata, to allow material transport and communication. Another distinguishing feature of plant cells is the large central vacuole, which stores a water reserve as well as essential chemicals, waste products of cellular metabolism, and sometimes other species-specific functions, such as storage of poisons or flower pigments. The central vacuole can also aid in cell growth by absorbing water.\n\nExcluding a few photosynthetic protists and cyanobacteria, plant cells are the only cells that contain chloroplasts. These organelles carry out the processes of photosynthesis, converting light energy into chemical energy and storing it as sugar. As well as producing food for ecosystems, photosynthesis releases oxygen molecules as byproducts, which replenish atmospheric oxygen used in cellular respiration and form a layer of ozone, O3, which shields the earth from solar ultraviolet rays.\n\nPlants probably evolved from multicellular green algae called charophytes and were the first multicellular organisms to colonize land. In order to do this, plants had to evolve several new characteristics in the form of distinct, specialized organs, which protists and algae lack. First of all, plants need to have a form of anchorage in the ground and rigid stem tissue for support. Thus, plants have developed root structures, which, in addition to anchoring a plant in the ground, allow the plant to take up chemical nutrients from the soil. Cellulose-containing cell walls developed in plant cells to maintain a form of rigidity in the part of the plant above ground. These account for the stiffness of plant stems and from the hardness of wood. Marine algae, which are suspended in water and can absorb nutrients from all around, have neither of these structures. Also, to prevent water loss in a terrestrial environment, plants evolved a waxy cuticle, which covers stem and leaf surfaces. Gases for photosynthesis can not diffuse across this cuticle, so tiny pores called stomata are present in the cuticle.\n\nBecause plants have organs that serve different functions, they must have systems to distribute necessary substances throughout the plant. Sugars, produced in photosynthesis, must be distributed to the body and roots of the plant that do not photosynthesize. Water and nutrients from the soil, taken up by the roots, must also make their way into the plant body and leaves. To perform these essential functions, plants contain a vascular tissue network, which consists small tubes running throughout the plant. There are two types of vascular tissue: xylem, which are small tubes dead cells that transport water and minerals up from the roots, and phloem, which are living cells that distribute sugars produced in photosynthesis.\n\nAlso characteristic of plants, as well as some algae, are gametangia that protect gametes. These are pockets of cells that protect the egg cell, and where the egg is fertilized.\n\nPlants have a life cycle unlike that of any animal, fungus, or bacteria. Probably a trait inherited from protistan (algal) ancestors, diploid and haploid generations alternate

this depends on the plant...different plants have VERY different requirements!

i always thought they were called "T-4 Plants" they live in the desert. They conserve ware by keeping their stomata closed because in normal plants stomata leaks out water

I would immediately say sunlight, but this would really depend on the conditions. Sunlight is more intense and therefore contains more energy than artificial light, however artificial light could be on all the time. This basically has to do with the amount of light/energy a plant can absorb/convert into plant in a space of time. I would still go with sunlight, more environmentally friendly :)

Remember that evolution usually takes the path of least resistance.  C4 metabolisms are an advance over C3 by compartmentalization.  This means creating specialized tissues.  Specialized tissues are metabolically expensive to form and maintain.  If a plant can get by with a C3 metabolism for all of its shortcomings and in-efficiencies it will do so.  Also C4 metabolism is adapted for periodic high intensity heat.  A great majority of the world does not experience that type of environment so that type of adaptation is not necessary.  When you look at it that way you could also ask why more plants don't have a CAM metabolism.

Well if I remember this right...NASA was doing experiments a few years ago with rhubarb and pumpkin plants. The C02 oxygen exchange was the greatest. Also there was something about a genetically engineered algae they were trying out

there is no C10 there is only C4

sunlight stimulates photosynthesis and larger amts produce more growth, lesser amts less growth.......Seasonal light changes inc growth in the spring as light hours incresae, and Fall lesser light as days dec in length slow growth. Same goes for daily changes......Strings of Rainy days vs sunny days!!!! Look outside if you live on the Eastern coast of the US......

Okay, the difference between water and soda is the addition of sugar and CO2. Some plants can actually metabolize sugar, and they all breathe in CO2, which sounds good. But, the CO2 is under pressure, or it wouldn't stay in solution, so it will probably increase the pressure inside the plant's cells. Which, depending on the plant, may rip it apart. Or not. Hope that helps.

Close because the plant takes in CO2 and so it will prevent any CO2 from leaving the cell because it need them to carry out photosynthesis. Once they have enough, the stomata are closed so that they don't escape.

They don't ALL release oxygen 24hrs a day guys! Oxygen is released during the process of photosynthesis. Photosynthesis requires sunlight. Is it bright and sunny in the middle of the night?! \nThat was a response to the previous answerers... I am sorry, I don't know the answer to your question! Perhaps it could relate to the photosynthetic pathway of the plant, eg C4 or CAM rather than just C3? That's just a random guess though. Good luck...

plants consist of cells lik anmals have.the difference is plants contain chloroplast to make their own food and animals dont have chloroplast but plants do contain mitochondria lik anmal cells and thus keep utilising the food  by respiration that they  had made during photosynthesis.if they dont  bring about resperation that is utilisation of the food they make thy will die hence plants carry out photosynthesis and respiration tooo

Several types. Read about it at http://horticulture.coafes.umn.edu/vd/h5015/99papers/kostreba.htm

there are only 2, the substituent can be on C1/C4 or C2/C3.
