Students planted several radish plants (Raphanus sativus) in their school garden. Students were allowed to take some of the plants home. One student observed that the plants grown at home were taller and had more leaves. She proposed the idea that genetic differences were responsible for the differences between the plants grown at school and the plants grown at home. Which of the following is the best argument against this idea?
Genetic factors cannot influence plant height or leaf growth.
Environmental factors are usually stronger than genetic factors.
The genetic materials of all the plants would be the same.
Changing environments can alter a plant's genetic material.

Some plants, like coleus, will wilt completely when water is limited. However, the aloe plant does not typically wilt under the same conditions where water is limited. Which statement best explains the differences in these two plant types?
Water availability is a genetic factor that causes the leaves of the plants to move differently in the two plant types.
Water availability is an environmental factor that affects coleus plants only since aloe plants do not require water.
Water availability changes the genetics of the plants, causing them to react differently to the water conditions.
Water availability is an environmental factor that affects plants, but there are genetic factors that affect how plants deal with the water loss.
