What is Zoochory?
zoochory (uncountable) The dispersal of seeds, spores, or fruit by animals..
What is seed dispersal by explosion?
Some plants distribute their seeds by violently ejecting them so that they fall well away from the parent plant. This is explosive dispersal. … As the two halves curl back, suddenly released like a tense spring, they flick out the seeds inside in an explosive manner.
What are 3 ways animals disperse seeds?
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.
Which seeds germinate quickly?
The fastest germinating seeds include everything in the cabbage family – bok choi, broccoli, kale, cauliflower etc, and lettuce. The slowest seeds to germinate are pepper, eggplant, fennel, celery, which may take 5+ days. The rest such as tomato, beets, chard, squash, onions, will take about 3 days.
How are seeds scattered by animals?
Animal dispersal Animals disperse seeds in several ways. First, some plants, like the burr at left, have barbs or other structures that get tangled in animal fur or feathers, and are then carried to new sites. Other plants produce their seeds inside fleshy fruits that then get eaten be an animal.
What seeds are carried 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.
Do birds poop out seeds?
Birds ingest the flavorful pulp; the seeds inside the pulp then move through the birds’ digestive systems and are passed out along with their droppings. The fecal material gives seeds a small dose of fertilizer.
What seeds are 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.
Do birds pee?
The answer lies in the fact that birds, unlike mammals, don’t produce urine. Instead they excrete nitrogenous wastes in the form of uric acid, which emerges as a white paste. And uric acid doesn’t dissolve in water easily.
Do birds have a stomach?
Birds all have two parts to their stomach. The first is called the proventriculus or glandular stomach, where digestive enzymes are secreted to begin the process of digestion. … The second part of a bird’s stomach (a part we humans don’t have) is the gizzard or muscular stomach.
Why do plants scatter their seeds Class 5?
Answer: Plants scatter their seeds in order to insure that they don’t grow to close to each other.
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. An example of a seed that travels by water would be the coconut seed.
How do plants spread seeds to humans?
Humans may disperse seeds by many various means and some surprisingly high distances have been repeatedly measured. Examples are: dispersal on human clothes (up to 250 m), on shoes (up to 5 km), or by cars (regularly ~ 250 m, singles cases > 100 km). … Deliberate seed dispersal also occurs as seed bombing.
What are the seeds dispersed by birds?
On Their Bodies Seeds can stick to birds’ feet or bodies with small hooks or barbs from the seed structure. This is known as Adhesive seed dispersal, or epizoochory.
What seeds are carried by the wind?
Wind dispersal Seeds from plants like dandelions, swan plants and cottonwood trees are light and have feathery bristles and can be carried long distances by the wind. Some plants, like kauri and maple trees, have ‘winged’ seeds. They don’t float away but flutter to the ground.
Do birds digest seeds?
Seed-eating birds utilize a unique process in order to digest their hard-shelled diets. Bits of cuttlebone also help to grind seeds, but only temporarily. … Pigeons swallow huge amounts of gravel, as they consume their seeds shell and all.
How do apple seeds get dispersed?
Answer. 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 seeds have little hooks that can stick on to an animal’s furry coat.
