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..
Why is a seed important?
Seeds are of immense biological and economic importance. They contain high protein, starch and oil reserves that help in the early stages of growth and development in a plant. These reserves are what make many cereals and legumes major food sources for a large proportion of the world’s inhabitants.
What are the advantages and disadvantages of seed dispersal?
Seed dispersal is likely to have several benefits for plant species. First, seed survival is often higher away from the parent plant. This higher survival may result from the actions of densitydependent seed and seedling predators and pathogens, which often target the high concentrations of seeds beneath adults.
Why are fruits and seeds dispersed?
In addition to protecting the embryo, the fruit plays an important role in seed dispersal. Seeds contained within fruits need to be dispersed far from the mother plant so that they may find favorable and less-competitive conditions in which to germinate and grow.
How does seed dispersal work?
Seed dispersal 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.
How do humans help in seed dispersal?
1) Yes humans helps in dispersal. Humans eat various fruits and vegetables and throw their seeds after eating. … Being lighter due to hairs, they are carried away by wind and thus they are dispersed.
