The Journey of Seeds: Agents of Dispersal and Their Impact on Plant Growth

The video explains the process of seed dispersal, highlighting its importance in plant growth. It covers various agents of dispersal, including wind, water, explosion, and animals, and discusses how each contributes to spreading seeds over distances. The video emphasizes the necessity of dispersal to prevent competition for resources between parent and new plants.

What is the primary reason for the dispersal of seeds away from the parent plant?

• To ensure seeds are planted in nutrient-rich soil

• To prevent competition for resources between parent and offspring

• To increase the size of the parent plant

• To protect seeds from predators

Which of the following plants uses wind for seed dispersal?

• Peas

• Dandelion

• Coconut palm

• Lotus

How do seeds of plants like lotus and coconut palm get dispersed?

• By wind

• By water

• By animals

• By explosion

Which method of seed dispersal involves the bursting of pods?

• Wind dispersal

• Water dispersal

• Dispersal by explosion

• Animal dispersal

Which of the following plants is known for dispersal by explosion?

• Dandelion

• Lotus

• Broom

• Cherry

How do animals contribute to seed dispersal?

• By protecting seeds from predators

• By planting seeds in the ground

• By eating fruits and excreting seeds elsewhere

• By carrying seeds on their fur

What happens to seeds that pass through a bird's digestive system?

• They are digested completely

• Their hard cover softens, aiding germination

• They are destroyed by stomach acids

• They become harder and less likely to germinate

Which of the following fruits have seeds that are commonly dispersed by animals?

• Coconut

• Dandelion

• Blackberry

• Peas

Why is seed dispersal by animals beneficial for plants?

• It ensures seeds are planted in nutrient-rich soil

• It allows seeds to travel long distances

• It prevents seeds from being eaten by other animals

• It helps seeds to germinate immediately

What is a potential consequence of seeds being planted too close to the parent plant?

• Protection from predators

• Increased growth rate

• Better access to sunlight

• Competition for resources
