What is seed dispersal called?

Seed dispersal is the movement, spread or transport of seeds away from the parent plant. There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals. Some plants are serotinous and only disperse their seeds in response to an environmental stimulus.

Regarding this, how is a seed dispersed?

Plants disperse their seeds in lots of different ways. Some seeds are transported by the wind and are shaped to float, glide or spin through the air. Some seed pods are designed to explode and throw the seeds a good distance from the parent plant. Many plants also use animals to carry their seeds.

Beside above, what is fruit and seed dispersal? The fruit has a single purpose: seed dispersal. Seeds contained within fruits need to be dispersed far from the mother plant, so they may find favorable and less competitive conditions in which to germinate and grow. Seeds dispersed by water are contained in light and buoyant fruit, giving them the ability to float.

In respect to this, what are 4 ways seeds can be dispersed?

Seeds disperse in four main ways, by air, water, animals and self propulsion:

  • Wind dispersal. Wind can carry seeds away from their parent plant.
  • Water dispersal. A few species use water to disperse their seeds.
  • Animal dispersal. Animals find fruits a rich source of food and as a result aid seed dispersal.
  • Explosion.

Why is seed dispersal important?

Dispersal of seeds is very important for the survival of plant species. If plants grow too closely together, they have to compete for light, water and nutrients from the soil. Seed dispersal allows plants to spread out from a wide area and avoid competing with one another for the same resources.
