Major test Unit 7 24th of June via Classmarker

What is the function of the calyx (sepals)?

1. attract insects
2. reproduction
3. protection against cold
4. producing nectar

What is self-pollination?

From pollination to----> fertilization (in plants)

How does a pollen grain nucleus reaches the ovule?

In the video you saw an example of seed dispersal by

1. the wind
2. the plant itself
3. animals

Find a nice photo of seed dispersal by animals
