why do seeds have different color?

All sorts of reasons.\n\nSome seeds are coloured black because those pigments provide protection from sunlight and microbial attack. (Apples)\n\nSome seeds are grey because they are black seeds with a thin white coating. (Poppies)\n\nSome seeds are brightly coloured to warn animls thatthey are poisonous and not to be eaten. (Coral tree)\n\nSome seeds are brightly coloured so that birds will eat them  and spread them around (palm 'berries').\n\nSome seeds are straw coloured because they are coloured only by the  colour of the cellulose coating, so they become literally the same colour as dry grass. (Wheat)\n\nSome seeds are brown because they are covered in woody material hat helps protect them from being eaten. (Coconuts)\n\nAnd on and on. Every seed has evolved its own colouration depending on how and what it is supposed to do.

The bulk of the seed is made up of a carbohydrate-rich "tissue" (although its not alive) called the cotyledon. Seeds are divided by the number of cotyledons they posess.  Corn is a monocot (one cotyledon), however, larger seeds are often dicots (two cotyledons). \n\nIn seed anatomy, the cotyledons protect the embryo and give it nutrients with which to germinate.  A full-grown plant makes its own food through photosynthesis, however, when a newly germinated plant is underground and therefore without sunlight, the cotyledons provide it with nutrients with which to grow.

It would depend on the species of tree. Some seeds need things to happen to them before they can sprout, such as being buried for a while and then unearthed, or drying out and getting wet again, or passing through the digestive tract of a bird.

Yes. In many plants their is a set ratio of height to base\nroot length therefore the depth of the seed may vary your\nplant height.

Possibly because single genes cause single, distinct, visible results. I think the colour of the kernels can be used (red, white or yellow or a mixture of these colours) to decide if the genes are dominant or recessive. In other fruit and vegetables colour is more variable, or depends on several genes. Corn (maze) also grows faster than peas, and certainly faster than apples, and the results can be seen before the ear is ripe, so you don't have to wait as long for the results. \n\nHope this helps

Seeds have a hard outer shell which withstands the cold winter and protects the young plant inside.\nIt is broken down enough by the winter weathter that in the spring when the weather warms and signals the young plant inside to grow, it is not hard enough to cause the plant not to be able to break free of it.

It's no use trying to find that out. Those conditions are to be fully controlled to get "non-colored" products.\nAnd be careful with what you use in food products!!

Because the different monitors interpret colors differently.

Isn't it the fruit?  Flowers on a strawberry plant are small and white with yellow centers.  As with most fruit, this flower is the site that turns into the edible fruit that contains seeds for dispersal.

The color depends mainly on three factors:\n\n1: The material. Different materials burn with different color\n\n2: Temperature. A material subjected to different temperatures will glow with different colors. (The speed through the atmosphere will give different temperatures)\n\n3: Distance to object. Colors are spread because of the air in the atmosphere, just look at the Sun, red when the light travels far through the air and yellow/white when the distance is shorter.

It's a question of genetics. Different genes will lead to different quantities of various substances produced and present in some part of your body. Eye color is mainly determined by the pigment melanin (the same that gives you a tan when you lie in the sun). \n\nIf your eyes have a lot of it, they're brown. If they don't, they're blue. Green eyes result from yellowish flecks of a fatty pigment against a dark background, and no melanin.\n\nThere you go :-)

A seedless grape is genetically altered to never mature enough for seeds to form, they are there but in smaller mushier form so you cant tell theyre there. like the small immature white seeds in a watermelon but to answer you question. they plant a seed.

Various plants have different accessory pigments in addition to chlorophyll.These various pigments are more efficient at using different wavelengths or under low or bright light conditions. For instance, many rain forest plants that live on the forest floor have a reddish undercoating to trap certain wavelengths of light. So, the various colors are adaptations to handle different growing conditions and allow the plant to grow adequately in areas where other plants cannot grow well.

In every packet of grass seed, there is one, genetically "rogue" seed.  This seed germinates at a slower rate than the rest of the grass seed.\n\nThe regular grass seed (such as creeping red fescue, for instance) grows to become a healthy, even sward.  The single, irregular seed pushes out a single, pointed root downwards.  The root carboniferises into a woody stem, from which a large, single leaf protrudes upwards.  This leaf, in the shape of a flat, regular-sided square or rectangle grows at an angle of ninety degrees to the root.  The outer-facing side of the leaf develops markings which appear in the form of letters reading "KEEP OFF THE GRASS".\n\nHope this helps.

they share all the same genes and the both help propagate the plant the runner makes new plants that are genetically the same as the others and the flower through sexual reproduction makes genetically varied seeds which will eventually become new plants

There has to be more info than that!\n\nThe only possible explanation I can give would be if you blue kernals with red kernals.  If mixed, they could produce purple.  The parent kernals could have a mix of dominant and recessive blue and red traits and still produce purple.

Direction doesn't matter so much as "orientation".  Many seeds have an up, and a down.  If you plant them the wrong way up, it doesn't really matter except that the stem growth will come out and have to "go around" the rest of the seed to head upwards and out towards the sun.  This uses up some of the energy stored in the seed, so that plant might not do as well as one planted with the right orientation.\n\nhope this helps...
