The _______ is sticky and receives pollen from pollinators, to transfer to the ovaries. To protect their seeds and allow for dispersal, plants can develop _______ to protect the seeds.

Answer:

1. corn

2. Ethylene

3. dormant

4. anther

5. stigma

6. fruit

7. temperature

8. Wind pollination required a great deal of excess pollen, just so some of it lands, by chance, in the right place. Animal pollination is more selective because animals pick pollen up and carry it directly to where it needs to be. Although there is still a chance that the pollen will be from the wrong plant species, plants can manipulate variations in animal behavior through the structures of their flowers, the time and season of flowering, or the rewards or attractive chemicals they produce to narrow the field of pollinators, and increase the chances of having exactly the right pollen put in exactly the right place.
