Plants can be stressed out just as people can. Discuss plant stresses and the responses of the plants.
What will be an ideal response?
To engage students, start with a general discussion of what stresses them and move to what students think could stress plants, for example, a lack of water, ozone, too much salt in the soil, heat, and not enough minerals.Focusing on one type of stress, such as insect attacks or wilting, ask students what is the response of some plants. Why, for instance, do some plants not wilt. Students will be interested to know that environmental stressors, such as a lack of water, generally induce a cellular response as the plant adapts to the negative stressor. Some plants cannot adapt and they wilt, but others adapt by, for example, pumping ions into their cells, so they retain water and do not wilt. Plant stressors and how plants adapt
are an important research area since understanding adaptation responses
could lead to the production of GM crops that resist drought or insect
attack or could grow in salty soil.
