why do seeds need to be dispersed
How can some plants reproduce without seeds? Some plants are able to reproduce without releasing seeds asexually using a specialized stem called a rhizome or by releasing spores. Bulb plants, such as. How are spores and seeds alike and different? Spores and seeds are alike in that plants produce them both to disperse their progeny, allowing new organisms to grow in different locations than their par. How do spider plants reproduce? Spider plants can reproduce by seeds, by dividing the plants or by potting up the plantlets.
Spider plants possibly get their name from the plantlets that. How does fertilizer affect plants? Fertilizers are much to plants what vitamins are to humans; they provide supplemental nutrients and minerals that plants might not otherwise obtain due to.
Seeds are dispersed to avoid the overcrowding of a plant species in one locality and to ensure the geographic spread of a plant across relatively large areas.
There are several mechanisms used for seed dispersal. Light seeds, such as dandelion seeds, spread across wide areas as the wind blows. Some seeds, such as coconut seeds, are waterproof and can be carried by a current of water over long distances. Some seeds have hooks that allow them to attach themselves to the fur of animals passing by, and they are then dropped at a location far away from the parent plant. Usually, seeds are contained within a fleshy fruit that is edible to most animals.
These seeds survive the passage through the gastrointestinal tract of the animal that consumed the fruit and are left behind by the animal along with some fertilizer to help the seed grow and survive. Some plants do not depend on external agents like wind, water or animals to disperse their seeds. Instead, their fruits have a mechanism that allows them to burst open with enough force to spread the seeds out away from the parent plant
