Seed Dispersal

How does animal behavior influence seed dispersal?

• Animals may eat fruits and excrete seeds in different locations, aiding in dispersal.

• Animals help in seed dispersal by burying seeds for later consumption.

• Animals do not play a significant role in seed dispersal.

• Animals primarily disperse seeds through their fur.

What is the primary purpose of seed dispersal?

• To move further away from the parent plant.

• To increase the size of the parent plant.

• To attract more pollinators to the parent plant.

• To provide nutrients to the parent plant.

How do burrs contribute to seed dispersal?

• They are carried by the wind to new locations.

• They cling to the fur of animals, which transport them to new locations.

• They float on water to reach distant shores.

• They are eaten by birds and excreted in different areas.

What adaptations do seeds have for wind dispersal?

• Heavy shells for stability

• Lightweight structures, wings, or parachutes.

• Sticky surfaces for attachment

• Thick coatings for protection

What is the impact of human activity on seed dispersal?

• Human activities can enhance natural dispersal mechanisms.

• Human activities can disrupt natural dispersal mechanisms and affect plant populations.

• Human activities have no impact on seed dispersal.

• Human activities only affect animal species involved in seed dispersal.

What is the term for seeds that are dispersed by animals after being eaten?

• Endozoochory

• Exozoochory

• Hydrochory

• Anemochory

What method is used for the dispersal of dandelion seeds?

• By water.

• By animals.

• By wind.

• By gravity.

Give an example of a plant that uses water for seed dispersal.

• Coconuts

• Dandelions

• Maple trees

• Sunflowers

How are raspberry seeds primarily dispersed?

• By wind.

• By water.

• By animals.

• By gravity.

What is the significance of seed dispersal for plant species?

• It helps reduce competition among seedlings and allows colonization of new areas.

• It increases the likelihood of seed predation by animals.

• It ensures that all seeds germinate in the same location.

• It prevents genetic diversity among plant populations.
