Plant Science

What is the definition of "Botany"?

• The study of plant genetics.

• The study of plant growth, characteristics, and their relationships with the environment.

• The exploration of diverse plant species.

In which century was the John Innes Centre initially founded?

• 19th century

• 20th century

• • 21st century

Provide an example of a plant mentioned for treating burns.

• • Lemon balm

What term is used to describe the study of how different cultures use plants for medicine?

• • Ethnoscience

• • Ethnobotany

• • Ethnography

How is plant resistance to high temperatures (heat resistance) achieved?

• Increase in cytoplasm viscosity and the content of osmotically active substances.

• Leaf wilting.

• Increase in substance transport.

• Enhancement of gibberellins activity.

What changes occur in a plant during water stress?

• Increase in carbon dioxide intake and photosynthetic intensity.

• Closure of stomata and reduced carbon dioxide intake, leading to a decrease in photosynthetic intensity.

• Increase in the activity of enzymes catalyzing synthesis processes.

• Stability in the structure of chloroplasts and high enzyme activity in photosynthesis.
