Learn how the seeds dispersal

1. Dispersal
Living things plants
Page 41 Scb

2. dispersal
When the fruit is ripe. The seeds are
ready to be scattered. Spreading the
seeds is called dispersal. If the seeds just
fell under the parent plant there would
be no room for them to grow. They must
be carried away to new ground. The
diagrams show some ways seeds are
adapted to ensure they dispersal

4. Some seeds pods burst as they dry;
the explosion scattered the seeds
away from the parent plant

5. Seeds may have wings or parachutes
so that they are carried by the wind

6. Seeds from waterside plants may
float away to new ground

7. Sweet juicy fruits attract animals
who scatter seeds as they feed

8. Some seeds have hook so they
stick to animals fur

9. Activity 3
collecting seeds
Make a collection of seeds
dispersed in different ways
Make a display.
Group and label the sees by the
way they are dispersed

flower parts to female parts. The pollen _______
the flower, and the ovules develop into _____.
The ovary becomes the ________. When the fruit

1. draw a labelled diagram of an insect-pollinated
flower.

12. 2. What causes a flower to make
seeds?
Pollination
* Describe the stages of the
process
the male pollen fertilises the female part of a
flower
The ovules start to change into seeds
The ovary becomes a fruit

13. 3. describe the different
mechanisms by which seeds may
be dispersal
