What is seed dispersal?
Seed dispersal is the technique of watering seeds near the parent plant.
Seed dispersal is the process of spreading seeds away from the parent plant.
Seed dispersal refers to the growth of seeds into new plants.
Seed dispersal is the method of planting seeds in the soil.
Name one method of seed dispersal.
Water dispersal
Wind dispersal
Animal dispersal
Gravity dispersal
How do animals help in seed dispersal?
Animals disperse seeds by eating fruits and excreting seeds in new locations, or by carrying seeds on their bodies.
Animals assist in soil aeration and nutrient cycling.
Animals help by pollinating flowers and aiding in plant growth.
Animals contribute by creating habitats for plant species.
What role does wind play in seed dispersal?
Wind aids in the dispersal of seeds by transporting them away from the parent plant.
Wind prevents seeds from germinating by keeping them close.
Wind has no effect on the movement of seeds in nature.
Wind helps in the growth of seeds near the parent plant.
Can you give an example of a plant that uses water for seed dispersal?
Coconut (Cocos nucifera)
Maple (Acer)
Dandelion (Taraxacum)
Palm tree (Arecaceae)
What is the purpose of seed dispersal for plants?
To attract pollinators for better growth.
To ensure seeds remain close to the parent plant.
To provide nutrients for the seeds during germination.
The purpose of seed dispersal for plants is to spread their offspring to reduce competition and increase survival chances.
How do seeds that stick to fur get dispersed?
Seeds that stick to fur get dispersed by attaching to animals, which carry them to new locations.
Seeds are eaten by animals and excreted elsewhere.
Seeds are carried by the wind to distant places.
Seeds are dispersed by falling to the ground and rotting.
What is the difference between active and passive seed dispersal?
Active seed dispersal is solely dependent on wind, while passive seed dispersal is plant-driven.
Active seed dispersal occurs only in animals, while passive seed dispersal is done by plants.
Active seed dispersal uses gravity, while passive seed dispersal uses animal movement.
Active seed dispersal involves active mechanisms by the plant, while passive seed dispersal relies on external forces.
Why is seed dispersal important for ecosystems?
Seed dispersal leads to increased soil erosion and habitat loss.
Seed dispersal is primarily beneficial for urban development and agriculture.
Seed dispersal has no impact on animal migration patterns or food sources.
Seed dispersal is important for promoting plant diversity, reducing competition, and supporting wildlife.
How can humans impact seed dispersal?
Humans impact seed dispersal by planting trees in urban areas.
Humans impact seed dispersal by using pesticides on crops.
Humans impact seed dispersal by creating artificial lakes.
Humans impact seed dispersal by altering habitats, transporting seeds, and engaging in agricultural practices.
