Question

1. Healthy soil (Links to an external site.) is vital to plant nutrients and to the health of humans. Good soil produces healthy plant life which results in a well-fed animal population. When soil gets polluted the entire food chain suffers; creating a huge number of problems. How does soil pollution affect plant growth? How, then, might the pollution affect humans either directly or indirectly? Research and provide 2 examples.

2. The 40 Fruit Tree. Plants have the impressive ability to reproduce asexually and regenerate damaged parts. The secret to these abilities lies within a tissue type called meristem.

Most plant meristems are located at the tips of shoots and roots and in cylindrical layers within stems and roots. What do you think would happen if they were present in leaves? Also, fruit trees cannot be reproduced "true" to the original cultivar from seed. They can only be reproduced by grafting. How does plant grafting strengthen our fruit-bearing crops? How does grafting use plant meristems?
