How are these seeds dispersed?

There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals. Some plants are serotinous and only disperse their seeds in response to an environmental stimulus. Dispersal involves the letting go or detachment of a diaspore from the main parent plant.

How are fruit seeds dispersed?

Seeds are dispersed in several different ways. These fruits, including the seeds, are eaten by animals who then disperse the seeds when they defecate. Some fruits can be carried by water, such as a floating coconut. Some seeds have little hooks that can stick on to an animal’s furry coat.

How many seeds does a litchi have?

The fruits are oval to round, strawberry-red in colour, and about 25 mm (1 inch) in diameter. The brittle outer covering encloses a translucent white fleshy aril and one large seed.

Which fruit seeds are dispersed by water?

Seeds dispersed by water are contained in light and buoyant fruit, giving them the ability to float. Coconuts are well known for their ability to float on water to reach land where they can germinate. Similarly, willow and silver birches produce lightweight fruit that can float on water.

How do plants explode?

There are three main elements that combine to create a plant explosion: heat, the creation of gas, and a dangerous reaction. Sometimes, plant explosions are caused by the use of impure chemicals. Impure chemicals may produce large amounts of gas, which can trigger a dangerous reaction and ensuing explosion.

Is Mango an indehiscent?

Drupe or stone – a fleshy indehiscent simple fruit that develops from a simple ovary, with the layers of the pericarp distinctly separated. In most fruits, the mesocarp is fleshy when ripe (e.g. mango).

Why is lychee bad for you?

Unripe lychees contain toxins that can cause extremely low blood sugar. This could lead to an encephalopathy, a change in brain functioning, said Dr. Padmini Srikantiah of the Centers for Disease Control and Prevention office in India, who led the investigation in Muzaffarpur.

Is Litchi a false fruit?

False fruit are found in numerous Angiosperm taxa. The edible false fruit of the longan, lychee and ackee fruits are highly developed arils surrounding the seed rather than a pericarp layer.

What plants disperse seeds by 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.

What is bursting of seed?

The bursting of seeds are triggered by many environmental factors such as wind, rain and physical contact with an animal. If an animal triggers the seeds to burst, it may stick to the animal, enabling seed germination far away from the parent plant.
