why do plants produce seeds???

This is so they ensure the survival of the plant species by reproducing them self's.  The seeds attract birds and animals to eat them and they in turn help spread the seed.  This is more efficient than pure wind distribution.

The main purpose of a fruit is to aid the growth and or transportation of a seed. Some fruits are designed to give the seed the required nutrients to start growing. Imagine a mouldy fruit on the floor gives the seed a chance to begin germination so it can get early nutrients and water before its root sytem has a chance to get them from in the ground. \n\nThis is common in areas where the water table is some way below the ground and or nutriens are hard to come by, so the root system has to be complex before a plant can obtain nutrients. these fruits would typically have a harder outer shell and taste sour, (lemon)\n\nOther soft fruits require help in transporttation and encourage birds etc to eat them and the seeds which then pass through the animal and germinate in a different place. These fruits are usually soft and sweet tasting (peach etc

No.\n\nLike most seeds it contains carbohydrate, protein and fat (oils). There are many minerals and some vitamins (though you would not select sweetcorn as a source of vitamins).\n\nThis is only to be expected since seeds must contain everything (except water) that an embryonic plant requires until it can grow above ground and then photosynthesise.\n\nAdditionally, the seed coat of many seeds is fairly undigestible and therefore provides dietary fibre (roughage). This is the only bit that does not provide nutrients, yet it is important in our diet.

if you're talking about plant cells, then it is for photosynthesis, the plant's way of making food. This is how it works.\n\nthe plant takes in carbon dioxide, water, and light. These are processed in the cell's chloroplasts and food is produced. The by-products of photosynthesis are sucrose (sugar) and oxygen, which is why we depend on rain forests and plants to give us a continuous supply of oxygen. In goes CO2 and out comes Oxygen!!

Some plants can reproduce asexually using their stems, roots or by producing bulbs. These plants can also have flowers and reproduce sexually.

Mostly plants flower and then make seeds. Sometimes the seeds are in the fruit like with pumpkins. In lettuce, the seeds happen after the flowers. Usually they pick the head of lettuce before it flowers so you don't get the seeds.\n\nWhen they grow seedless fruit like grapes say, they take cuttings from the vine and root them.

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.

All seeds are encased in some form of fruit. Fruit is anything that protects a seed. It doesn't neccessarily have to taste sweet and juicy like an apple. Nuts are a type of fruit, and they also encase seeds. Seeds are just what you said, an embryonic plant encased in a covering called the seed coat. Seeds are sort of like baby plants. They have everything that they need to grow except soil and sunlight. Now, the parents of these seeds what to protect their 'babies', so they give them more protection. They do this by wrapping the fruit around the seeds. Now, nuts are types of fruit, so they are also protecting the seeds. However, they are different from seeds. \n\nA nut is a seed, but not all seeds are nuts. A seed comes from fruit and can be removed from the fruit. A nut is a type of seed that is also a fruit, and the fruit and the seed cannot be separated (unless you're eating it).\n\nHope this helps!

There is a reason why plants only grow so high in nature.  They have to be able to still pump nutrients from the roots to the farthest limb.\n\nBesides, you would be providing a home for rats.

water really do play a vital role in seed germination because seeds undergo water imbibation (especially those seeds that have been dormant for quite a long time) in order to break the seed coat. however, when it comes to the percentage of water to be present in soil, that would actually depend on the kind of plant seed that you are germinating. there are those plant seeds that just requires soil to be moist (that is, most of the soil micropores are filled with water) and others would need more water molecules in the soil (soil macropores are filled with water).

wow at first i thought you meant how are insects useful to plants that eat them... but i guess you mean insects as a general usefullness to plants... its probably too broad to answer correctly...  but commonly they help disperse pollen, as with bees... or when they eat the fruit and defecate the seeds elsewhere... and insects also can eat other insects tht prey on the plant... they also trim and pare the plant naturally... and lastly they keep it company... plants cant move and really can get quite lonely sometimes...

welll, if you have a bunch of seeds, you have to germinate them to make them grow, the ones that dont germinate are no good.

there are tons of factors affecting plant growth. one of them is the kind of soil for the plant to grow. some plants need a specific type of soil in order to grow properly. another factor is the sunlight and food it gets. it needs the propwer nourishment for the palnt to fluorish. next is the nutrients that a plant need. some may need medicines to help them grow better.

When a seed starts to grow.\n'Germinate' comes from 'germ cell' or the cell from where the whole organism grows. So whenever the germ cell is activated and starts growing into the new organism, it is germination. It usually refers to when the baby root and stem start to push out from the seed capsule.

Tree: God created the plants & trees.  The seeds happened later to propogate the foliage.

some plants have hook shaped fruits.. it can hook onto animals n be carried off to different places\n\nDandelion has light featherlike seeds exposed to air that can be blown off with the wind\n\nPlants near waterbodies have seeds that can float on water.. so again they can be deposited in far off places\n\nThere r various other adaptations in the links below.. check em out..

Like the Dude said above.. they have flowers above the water.\nFlowers get pollinated, seeds grow, seeds are distributed thru the water, fall to the bottom and grow the next generation... its a circle of life thing.
