Is Mango dispersed by water?
Fruit bats will often grab the fruit off the trees, but they usually don’t take them very far. But given that mangoes are tropical they are likely that the seeds are moved around by torrential rain washing them around. Flying foxes and animals that eat the seed are responsible for dispersal of mango seeds.
What are the seeds 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.
In 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 can the seed be dispersed if it is eaten by an animal?
Animals can disperse seeds by excreting or burying them; other fruits have structures, such as hooks, that attach themselves to animals’ fur. Humans also play a role as dispersers by moving fruit to new places and discarding the inedible portions containing the seeds.
Why do seeds need to be dispersed?
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.
What do seeds need to germinate?
We know that seeds need optimal amounts of water, oxygen, temperature, and light to germinate.
What 3 conditions are needed for germination?
All seeds need water, oxygen, and proper temperature in order to germinate. Some seeds require proper light also. Some germinate better in full light while others require darkness to germinate. When a seed is exposed to the proper conditions, water and oxygen are taken in through the seed coat.
