Because plants cannot walk around and take their seeds to other places, they have developed other methods to disperse (move) their seeds. The most common methods are
wind, water, animals, explosion and fire
.
How are seeds spread naturally?

.
How are seeds spread?
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.
What is the process of spreading seeds?
Seed dispersal
is the movement, spread or transport of seeds away from the parent plant. … Dispersal involves the letting go or detachment of a diaspore from the main parent plant.
How seeds are scattered?
Seeds can be scattered in many ways. Some
seeds are scattered by the wind
, some are carried away by birds and insects, some float in water, others are forced away from the plant by exploding pods, and still others hitchhike on animals and people. … In this way the seeds are taken to a new location to grow.
Why is it important for seeds to travel?
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.
Do trees release seeds?
Trees produce seeds
in several ways. Some produce dry fruits that release their seeds at maturity. An example would be a Cottonwood tree whose fruits break open and fluffy seeds fly away. Other trees produce one-seeded fruits that separate from the tree without releasing its seeds.
What do seeds need to germinate?
- The beginning of the growth of a seed into a seedling is known as germination.
- All seeds need water, oxygen and the right temperature to germinate.
- Dormancy is a state of suspended animation in which seeds delay germination until conditions are right for survival and growth.
What makes a seed?
A seed is an embryonic plant enclosed in a protective outer covering. … Seeds are
the product of the ripened ovule, after fertilization by pollen
and some growth within the mother plant. The embryo develops from the zygote, and the seed coat from the integuments of the ovule.
What three parts do almost all seeds contain?
“There are three parts of a seed.” “A bean or seed consists of
a seed coat, an embryo, and a cotyledon
.”
What plants explode to disperse their seeds?
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.
What happens after a seed falls to the ground?
Once the seed pod bursts and cellular respiration begins, the tiny seedling gains the energy it needs to push up through the soil. The emerging plant will
begin to grow plant tissue
, forming the beginning of a stem. Most seedlings grow out of the seedling curled over, like a person touching her toes.
What seeds are spread 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 is the function of the seed?
Functions. Seeds serve several functions for the plants that produce them. Key among these functions are
nourishment of the embryo, dispersal to a new location, and dormancy during unfavorable conditions
.
How do animals help seeds travel?
Animals often eat fruits and seeds.
They then move to a new area where they poop out the seeds
. … They then move to a new area where they poop out the seeds. New plants grow from the seeds!
How does a hitchhiker seed travel?
What are Hitchhiker Weeds? Weed seeds spread in a variety of ways, whether traveling by water, by air, or on animals. … Their variously barbed adaptations ensure that the seeds will
travel far and wide via animal locomotion
, and most can be eventually shaken off down the road somewhere.
