Fertilisation and dispersal – Clip

The Alsometra plant produces large winged seeds that can glide hundreds of meters, allowing them to be dispersed far from the parent plant. This dispersal ensures that the seedlings have enough space and light to grow successfully.

What is unique about the seeds produced by the Alsometra plant?

• They are edible and nutritious.

• They have wings that allow them to glide.

• They are the smallest seeds in the world.

• They grow only in water.

How do the wings of Alsometra seeds benefit them?

• They protect the seeds from harsh weather.

• They make the seeds more attractive to animals.

• They allow the seeds to glide long distances.

• They help the seeds to float on water.

Why is it important for seeds to be dispersed far from the parent plant?

• To prevent them from germinating.

• To avoid competition for resources.

• To ensure they are eaten by animals.

• To keep them in the shade.

What happens to the seedlings that germinate far from the parent plant?

• They struggle to find light.

• They grow slower than those near the parent plant.

• They have more space and light to grow.

• They are more likely to be eaten by animals.

What is the main advantage of seed dispersal for the Alsometra plant?

• It helps the plant to grow taller.

• It allows the plant to produce more seeds.

• It ensures the survival of the species by reducing competition.

• It makes the plant more resistant to diseases.
