Question: What Are Two Ways Seeds Can Be Dispersed?

How is an apple seed dispersed by water?

In some plants seeds are housed within a fruit (such as apples or oranges).

These fruits, including the seeds, are eaten by animals who then disperse the seeds when they defecate.

Some fruits can be carried by water, such as a floating coconut.

Some seeds have little hooks that can stick on to an animal’s furry coat..

What are 2 ways that plant seeds can be dispersed?

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.

What types of seeds are dispersed by water?

Many marine, beach, pond, and swamp plants have waterborne seeds, which are buoyant by being enclosed in corky fruits or air-containing fruits or both; examples of these plants include water plantain, yellow flag, sea kale, sea rocket, sea beet, and all species of Rhizophoraceae, a family of mangrove plants.

What are the two major methods by which pine seeds are dispersed?

They can be dispersed in multiple ways. 1) Animals eat pine seeds and spread them around by defecating them and letting them grow. 2) Sometimes if the pine seeds are in a windy environment, they can be blown around and spread. 3) Some are dispersed by water.

Which seed is dispersed by animals?

Examples include mangoes, guavas, breadfruit, carob, and several fig species. In South Africa, a desert melon (Cucumis humifructus) participates in a symbiotic relationship with aardvarks—the animals eat the fruit for its water content and bury their own dung, which contains the seeds, near their burrows.

Which plants seeds are dispersed by explosion?

Violets, poisonous squirting cucumbers, and touch-me-nots or Impatiens capensis (not to be confused with these touch-me-nots) have an effective way of dispersing their seeds: They burst! The forceful ejection sends the seeds flying as far away as possible from the original plant.

How far can a seed travel in water?

Our analysis on existing seed data reveals that water‐dispersed riparian plants have relatively large seeds and are thereby evolutionarily adapted to long‐distance dispersal. Furthermore, our results indicate that median dispersal distances are 0.02–1.8 km (99‐percentile <8.5 km) in lowland streams in summer.

Which seed is dispersed by wind?

Other seeds are dispersed by the wind—such as the “winged” seeds from a maple tree that spin and “helicopter” through the air as they fall or the light feathery seeds from a dandelion that can catch on the breeze.
