 ===Gravity=== <!--T:6-->
-The effect of gravity on the dispersal of seeds and spores is straightforward.  Heavier seeds will tend to drop downward from the parent plant, and not by themselves travel very far.  Spores, being much lighter, are more influenced by physical movements in the environment, especially those of wind and water, and therefore less strictly subject to the simple motion of gravity (see examples below). Gravity may be sufficient agent for plants growing on steep slopes, but upslope movement of a population can be a problem. The naked seeds of gymnosperms are largely dependent upon gravity for dispersal. Most conifers are long-lived large shrubs or tall trees, thus taking full advantage of gravitational dispersal and allowing for gradual upslope movement of a population. Dispersal of seeds "strictly" by gravity should not overlook storm effects: seeds from a deteriorating cone growing high on a tall, narrow tree will get spread widely during a wind storm (see "Wind" below).

-For non-aquatic, terrestrial plants, the wind is an obvious supplier of energy for movement, and many plants clearly take advantage of this fact.

-Plants that grow in water (aquatic and obligate wetland species) are likely to utilize water to disperse their seeds.  For example, all mangroves disperse their offspring by water.

 === Requirements for seed germination === <!--T:48-->
 Seed germination depends on many factors, both internal and external. The most important external factors include: water, oxygen, temperature, and the correct soil conditions. Every variety of seed requires a different set of variables for successful germination. This depends greatly on the individual seed variety and is closely linked to the ecological conditions in the plants' natural habitat.
 ==== Water ==== <!--T:25-->
-Germination requires moist conditions. Mature seeds are usually very dry and need to take up significant amounts of water before they can "come back to life."  The uptake of water into seeds leads to a marked swelling. The pressure caused by water aids in cracking the seed coat for germination. When seeds are formed, most plants store large amounts of food, such as starch, proteins, or oils, for the embryo inside the seed. When the seed absorbs water, it breaks down these stored food resources and allows the seedling to germinate and grow until it reaches the light. Once the seedling starts growing, it requires a continuous supply of water and nutrients.
