how are differents seeds spread from place to place?

Some go airborne, some are transported by animals on their fur or in their droppings, some plants tumble away from their roots when the seeds are ready, and some just fall to the ground or into water and float away.

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.

1. Seed: a little baby plant, sleeping until the right time comes along\n2. Germination: the baby plant pokes out of its seed when there is enough moisture and the right temperature\n3. Growth: using energy from the sun and nutrients from the soil the plant grows to its full size\n4. Flowering: When it is big enough, the plant will start to make flowers so that it can make new seeds\n5. Pollination/fertilization: two types of plant parts must come together to make a new seed. Sometimes insects help this happen.\n6. New seed!

plants on land have a harder time spreading out their young, look at pollen and seeds.  water plants just release their gametes and they float away

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.

Nutrition (depends on certain soils: mixed compost, clay-like dirt, moss, bark etc.), Sunlight or other warmth, Air, Water, and depth of how far the seeds or roots are planted into the soil. Different plants require different depths when being planted.

Even though seeds aren't the earliest to hit the scene in plant evolution, as Djddan has stated, they have played a HUGE role in evolution...\nThe main thing is that seeds have given their parent plant an opportunity to travel! In general, plants are stationary organisms. Without means for locomotion (like most animals have), they must rely on their seeds to move for them. The reason is that it increases the area their genetic material can travel.\nIf seeds didn't travel, you would have huge pockets of areas that would have many genetically similar plants.\n\nSeeds ensure travel many different ways. Some have wings on them so that the wind can carry them away from their parent tree. Some are embedded in tasty fruit thhat get carried off by hungary animals. Some stuck to animals walking by, some are dropped into water and carried off by flowing rivers...The list goes on.\n\nSeeds have impacted evolution in huge ways. Hope this helps.

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.

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.

1. Wind- Some seeds are carried to a new place by the wind.\n\n2. Water Dispersal- Fruits which float such as those of the water lily and the coconut palm are carried by water.\n\n3. Animal Dispersal- Some seeds that are ingested by animals can be digested and later excreted out far away from the parent plant.  Some seeds also have burs so they can attach themselves to animal fur only to later be dropped.\n\n4. Explosion- Some plants have pods that explode when ripe and shoot out the seeds.\n\n5. Fire- A number of species of pine have cones that only open after a fire. These are called serotinus.  Jack pines have cones that are held closed by a resin sensitive to high temperatures. These cones will not open to release their seeds until a critical temperature is reached.

the birds pick out the seeds and carry them off and usually drop them somwhere. So that is what they have to do with it.

the egg stays where it is - in the ovary. it turns into seed there. so the pollen must germinate (into a structure called pollen tube) and this tube grows through the pistil and delivers the germ cells to fertilize the egg. cut open a ripening seed pod of a flower and u will see the growing seeds. or imagine a green pepper cut open or green peas in the pod -  the seeds are attached to something that is called placenta, actually. and before fertilization they were not seeds but eggs. and through this place of attachment they were fertilized. it is not like human egg that itself travels from ovary to uterus and gets fertilized on the way.

Bulbs can reproduce in two ways. One being bulb increment. That is where the bulb grows to a rather large size and then splits into one or more new BULBETTES which are fed from the MOTHER bulb. These BULBETTES then continues to grow with the MOTHER bulb forming a new plant with the ability to sustain itself (eventually). The second way in which a bulb can reproduce is by seeding. When the flowers bloom they are then cross-pollinated like any other plant and the seeds begin to form

Seeds when sown starts multiplying the cells and they grow as plant, flowers produce pollen grains which travels through air to produce plants.

Seed dispersal is the main process linking the spatial pattern of parent plants with that of their offspring (Harper 1977, Howe and Smallwood 1982, Willson 1992, Venable and Brown 1993, Chambers and MacMahon 1994, Schupp and Fuentes 1995). The spatial pattern of dispersed seeds serves as a template for subsequent processes such as predation, germination, competition, and growth that ultimately shape the spatial pattern of adult plants. The basic component of this spatial pattern is usually described by the "dispersal curve," showing the change, typically a rapid decline, in the density of dispersed seeds with increasing distance from the parent plant (Harper 1977, Okubo and Levin 1989, Willson 1993). In investigating the spatial pattern of tree regeneration in tropical forests, Janzen (1970) combined this dispersal curve with two other functions describing the change with distance in the per capita probability of seed survival to maturity (the "survivorship curve"), and in the density of recruits (the popula tion "recruitment curve"). Janzen (1970) and Connell (1971) proposed the escape hypothesis (Howe and Smallwood 1982), suggesting a positive slope of the survivorship curve, determined by the high mortality of progeny (seeds and seedlings) in the vicinity of adult plants, due to seed predators, parasites, pathogens, and seedling herbivores. They predicted that recruitment should occur mostly at some distance away from parent plants, whereas Hubbell (1980) argued that, with realistic dispersal and survivorship curves, recruitment should always be higher near adults because of the disproportionately high seed densities there. McCanny (1985) demonstrated how different slopes of the survivorship curve can produce, out of the same dispersal curve, positive (Janzen-Connell model), zero, and negative (Hubbell's model) slopes of the recruitment curves.
