Beetroot cells like any other eukaryotic cells have many types of cell organelle present. Some of these organelles are bounded by a single membrane, e.g. lysosomes, Golgi apparatus, vacuoles; some are bounded by two membranes (an envelope), e.g. nucleus, mitochondrion. Beetroot appears as a dark red/ purple colour and this is caused by the betalain pigment, which is contained within the vacuole of beetroot cells. In order for the betalain to leave the cell it needs to pass through 2 different membranes; the membrane bounding the vacuole and the membrane enclosing the cell.  the effect that temperature  on the movement of pigment through beetroot cell membranes is , By heating beetroot slices at different temperatures how this heat effects the cell membrane?\n\n\nWhen you heat a beetroot, you disrupt the cell membranes. A biological membrane is made of a so-called phospholipid bilayer. These are formed because the phospholipids that make it up have a polar "water-loving" (hydrophyllic) head and a “water-hating” (hydrophobic) tail. The tails pack together, exposing only the polar heads to the water. The most effective way of doing this is to create two blankets one atop the other, with the fatty acid tails towards each other. This is the phospholipid bilayer. \nIn a cell they form sacks. One goes all around the cell (the plasma membrane), others may form vacuoles (such as the tonoplast). Yet others may be like stacks of half empty bags (the endothelial reticulum, which is also continuous with the nuclear envelope.  In these lipid seas, there will be a number of proteins in various degrees of submersion. Some span all the bilayer, thus being exposed on both sides. Others just drift on either of its surfaces. Typically, you will find that about 70% of a cell membrane is protein. The water around and within the compartments formed by the phospholipid bilayers is also crammed with protein (= cytoplasm). \n\n\n\nSo what happens when you heat this? When you heat something you give it energy. Molecules start to spin and vibrate faster. The water will expand too. This will have a disruptive effect on any membrane in its way. To make things worse, lipids become more fluid as temperature goes up (think of what happens when you heat butter) so the membranes become more fragile. \nProteins are remarkable machines: they're formed of coiled and folded strings of amino-acids, held together by hydrogen bonds and disulphide bridges. If you heat them too much, they will untangle and break apart (vibrations again). When this happens to the proteins spanning a lipid membrane, they will form holes that will destroy the delicate structure. Now, any pigments in the innermost compartment will spill out.\n\n\nThe half-life of beetroot pigment is 413 mins at 250C but only 83.5 mins at 600C.  These values are doubled in 0.1% ascorbic acid.  Metal ions speed up the breakdown – iron is particularly effective.\nThey are stable between pH 4.0 and 7.0 – indeed, at high temperatures they are most stable in a pH between 4.0 and 5.0 – and most fruits and vegetables are acidic!\n\nconclusion: the membrane becomes more permeable at higher temperatures. This was explained by the fact that proteins denature with high temperatures and the phospholipids structure changes and becomes less stable.

This is due to the way we perceive objects.  When you look at something and see a color, you are merely seeing color being reflected back at you.  In theory, the sun (or lights in our houses) produce white light which consists of every color.  When white light hits an object, some of it reflects and some of it is absorbed.  In black objects, no light reflects and all of it is absorbed.  In white objects, all the light reflects and none is absorbed.  Similarly, the same is true about colored objects.  In red things, red light reflects and everything else is absorbed.  In blue objects, blue light reflects and everything else is absorbed.  Similarly with plants, the green leaves reflect green light and all the rest of white light (red, blue, orange, purple, etc) is absorbed and used as energy.  Specifically, it is the properties of chlorophyll A and chlorophyll B that cause this green reflection.  Oddly enough, in most plants there is some Betacarotine as well that reflects orange light.  There is just so much more chlorophyll that all we see is green.  However, in the fall when leaves start to die, the chlorophyll goes first and the betacarotine sticks around, causing the leaves to turn orange!\n\nHope this helps!

In contrast with the case of animals, many plants can hybridize (cross-fertilization between different species) and produce viable offspring. Plants deal with the different (non-matching) chromosomes from their parents by means of polyploidy, that is, instead of undergoing complete cell separation, they duplicate each chromosome and then retain the new pair, so that subsequent mitosis results in polyploid cells. These polyploid individuals usually are bigger, produce larger flowers and/or fruits, and may even be fertile. Even if they are not, their larger size and/or yield (as in crops) is advantageous for the agriculturers.\nPolyploidy can be induced by means of some substances (e.g. colchicine) that affect the cell and prevent its full division. The consequence is similar to the case of hybrids.

Different animals see different ranges of color.  Scientists can determine this largely by looking at the structure of the eye, to understand what light waves a structure responds to.

The most obvious (or unobvious) is the centriole found in some nuclei.\n\nMany cells also have ribosomes and vesicles which might be hard to see except under the highest powers.\n\nThe Golgi are also exceedingly small and difficult to see.

The most important feature distinguishing the cells of plants from those of animals is the cell wall. In plants this wall protects the cellular contents and limits cell size. It also has important structural and physiological roles in the life of the plant, being involved in transport, absorption, and secretion.

I don't have any picutres for you to look at, but I can give you an explanation.\nanimal cells are going to be more rounded, and plant cells are more rectangular.\nRemember: PMAT, these are the phases of mitosis\nProphase-the chromatin begins to condense into chromosomes and the nucleus begins to break down.\nMetaphase-The Chromosomes line up or Meet or "MET" at the cellular equator\nAnaphase- The chromosomes are pulled apart at the centromere\nTelophase- The chromatin decondenses and the neclues reforms\nAlso, the diff. between animal and plant cells....\nAnimal cells have a cleavage furrowl like a figure-8.\nPlant cells build a cell plate in between the separated chromosomes\nMitosis results in two daughter chromosomes.

Centrioles are found only in animal cells. Also, in plants, cell division mainly takes place in special regions called meristems. These rapidly dividing areas will either elongate the tips of the plants' stems and roots or expand their width. In animals, cells divide everywhere. Cytoplasmic division is also different in plant cells. Plants divide the two daughter cells by building new cell walls rather than by cleaving (pinching in two) as animal cells do.

Well considering that most cell components are organic then it is easy to see why. Organics must contain carbon!\nFe is not present as much as it isnt needed in large quantities. Large amounts may even be poisonous!

the shape of animal cell can be altered while plant cell have a fixed shape. \nplant cell have cell wall but animal cell have none. \nplant cell have ssap vacoule but animal cell have none  ( if there was one it is really small).\n\nother differences if you would like to know\nthe plant cell nucleus is at one side while the animal cell nuclues is centrally located.\nthe presence of chloroplast in plant cell while animal cell have none.

absolutly the same for most properties but they polariye light differently in fact they polarize the light in the same angle but with different sign, so if one is 30 deg the other is -30 or 330 deg... you can find more about them in wikipedia

Actually, the reason for this is known.  There are two major types of light-sensing cells in your retina, called rods and cones.  Cones are specialized for color vision and detail-they are concentrated in the central portion of your vision, so that when you look directly at something which isnt moving, you can see it very clearly, in color and detail.  The rods are black and white, and are specialized for low-light detection of movement.  Since the cones are in the center of your vision, there are more rods in the periphery of your vision.  If you think about it, this makes perfect evolutionary sense, since you want to quickly detect things moving in your periphery, so you can react to an attack-because humans have such excellent detail vision, we can detect things in our center of vision even when they arent moving (many carnivores, such as dogs, hve a difficult time seeing stationary objects), so we dont need such good "movement" vision in the center.  This arrangement also explains why color disappeas in low light, because cones require bright light, while rods work in dim light.  In addition, this explains why, in a dark room, you can actually see better in your peripheral vision-because the concentration of cones in the center of your retina is pretty useless in low light.

Because is a part of a plant and the apparatus of Golgi is an animal structures. They are not cloroplast because it is a root.

All cells have cell membranes.  They both have DNA and a lot of other stuff common to all life forms.  The main difference is that animal cells don't have cell walls but plant cells do.  If I were God, I would make animal bone cells have cell walls.  That would be cool.
