Describe what might be observed in a habitat that would indicate a plant species is allelopathic?

6. cultivar- a plant variety that has been produced in cultivation by selective breeding
▁▁▁▁▁▁▁▁▁▁▁▁

7. inbreeding depression (include how to prevent it)- is the reduced biological fitness in a given population as a result of inbreeding, or breeding of related individuals.

The first step in managing a hatchery population to prevent inbreeding depression is to decide what level of inbreeding causes problems. Unfortunately, there is no answer to this seemingly simple question.

8.seedbank (include reasons for having them)- A seed bank (also seedbank or seeds bank) stores seeds to preserve genetic diversity

Aside from crop diversity, there are many other reasons we need to store and preserve seeds:

Climate change: Scientists are concerned that climate change will cause extreme weather conditions and bring new pests into some environments. These events could cause certain species of plants to go extinct [source: Rosenthal].

Natural disasters: Natural disasters can wreak havoc on a region's ecosystem. After the 2004 tsunami destroyed rice paddies in Malaysia and Sri Lanka, international seed banks provided local farmers with varieties of rice to begin growing their crops again.

Disease: Disease quickly and easily wipes out crops. For example, a recent strain of the disease called stem rust may have the capability to infect up to 25 percent of the world's wheat supply.

Man-made disaster: Man-made disasters can be as devastating to plant life as natural disasters. An obvious example would be war. In fact, one of Iraq's vital seed banks was looted during fighting].Research: Indigenous people have used plants to cure sickness for centuries. One in every six wild plants is used for medicinal purposes. Who knows what diseases the right plant or herb could eradicate?
▁▁▁▁▁▁▁▁▁▁▁▁

9. gene promoter-  is a region of DNA that initiates transcription of a particular gene.
▁▁▁▁▁▁▁▁▁▁▁▁
10. genetic trespass-  is a technique to splice, 
delete, add, isolate, recombine or transfer genes from one 
organism to another that may be totally unrelated.
