10 Questions
The plants behind drought tolerance are complex and involve many pathways which allows plants to respond to specific sets of conditions at any given time
mechanisms
From an evolutionary perspective, the type of mycorrhizal ______ formed in the roots of plants can determine how fast plants can adapt to drought
associations
Some plants are naturally adapted to dry conditions, surviving with protection mechanisms such as ______ tolerance, detoxification, or repair of xylem embolism
desiccation
The intervention of ______ (such as sucrose, glycine, and proline), ROS-scavenging enzymes
osmoprotectants
Other plants, specifically ______ like corn, wheat, and rice, have become increasingly tolerant to drought with new varieties created via genetic engineering
crops
True or false: Horticulture only includes the cultivation of food crops such as fruits and vegetables?
False
True or false: Horticulture involves the use of hand tools such as digging sticks, hoes, and carrying baskets?
True
True or false: Anthropologists view agriculture as a less intensive strategy compared to horticulture?
False
True or false: Horticulture can involve landscape and garden design, construction, and maintenance?
True
True or false: The study and practice of horticulture have been traced back to ancient times?
True
Study Notes
Drought Tolerance in Plants
- Drought tolerance involves complex pathways, allowing plants to respond to specific conditions.
- The type of mycorrhizal association formed in plant roots can influence how quickly plants adapt to drought from an evolutionary perspective.
Plant Adaptations
- Some plants have natural adaptations to dry conditions, such as drought tolerance, detoxification, and repair of xylem embolism.
Protective Mechanisms
- Soluble compounds like sucrose, glycine, and proline can intervene to aid plant survival.
- ROS-scavenging enzymes also play a role in protecting plants.
Genetic Engineering
- New varieties of crops like corn, wheat, and rice have been created through genetic engineering to improve drought tolerance.
Horticulture
- Horticulture is not limited to the cultivation of food crops like fruits and vegetables.
- Horticulture involves more than just the use of hand tools like digging sticks, hoes, and carrying baskets.
- Anthropologists do not view agriculture as a less intensive strategy compared to horticulture.
- Horticulture encompasses landscape and garden design, construction, and maintenance.
- The study and practice of horticulture date back to ancient times.
