Which 3 conditions are needed for a seed to germinate? Plant dispersal mechanisms rely on anatomical and morphological adaptations for the use of physical or biological dispersal vectors. Adaptations for water dispersal include aerenchyma in fruits or seeds and light weight (e.g., water chestnut, Trapa natans; Lythraceae). When the coconut ends up in the ground, in the right environment, it produces a seedling that eventually grows up to become a coconut tree on its own, assuming that the conditions are favorable.

The phenomenon of Seed Dispersal helps in reproduction in plants. Water current is always in one direction so the seeds will germinate in the same place--disadvantage When the seeds germinate, they would have a source of water near them--advantages Prior to the experiment, land use and vegetation were mapped and samples of the soil seed banks on the slopes collected. Plant cells all have a _____ composed of cellulose. A hard shell encloses the insignificant embryo with its abundant endosperm, composed of both ‘meat’ and liquid.

The coconut's external husk protects the internal seed from predators and the salt of the ocean. Coconut seeds disperse by action of the ocean waves and by being deliberately planted by human beings. Coconuts floats on water and can float to another island and germinate there. Recently, studies of interactions between the dispersal unit and physical environment have uncovered fluid dynamic mechanisms of seed flight, protective measures against fire, and release mechanisms of explosive dispersers. The coconut tree's general appearance is its main adaptation to the climatic changes of heat and heavy winds. Coconuts are also too heavy to be dispersed by winds of normal strength. As the seed matures, the pod or husk dries out and may start to shrink around the seeds. The coconut has a thick fibrous husk surrounding a single-seeded nut. Plant seeds can be dispersed in a number of different ways. Seed dispersal allows plants to colonize new areas, far from the parent plant.
