Plant Defense Quiz

How do plant defenses help plants to survive?

• By deterring herbivores, attracting predators of herbivores, and defending against pathogens.

• By providing food for herbivores

• By offering shelter to herbivores

• By creating a welcoming environment for pathogens

What are some examples of physical plant defense?

• Thorns, spines, and trichomes

• Security cameras

• Guard dogs

• Fences and walls

Name a chemical plant defense used by plants.

• Sap and enzymes

• Loud noises

• Electric shock

• Physical barriers

Why is it important to know about plant defenses?

• To make plants more vulnerable to pests and diseases

• To increase the cost of agriculture

• To harm the environment by using more pesticides

• To protect crops from pests and diseases, and develop sustainable agriculture.

How do thorns and spikes help plants to protect themselves?

• They release a pleasant scent to deter predators

• They provide a source of food for animals

• They help the plant to attract more sunlight

• They act as a physical deterrent to prevent animals from eating the plant.

What are trichomes and how do they contribute to plant defense?

• Trichomes are small hair-like outgrowths on the surface of plants that can help deter herbivores and protect against UV radiation.

• Trichomes are a type of parasitic plant that feeds on other plants

• Trichomes are used by plants to attract herbivores for pollination

• Trichomes are a type of fruit found in tropical regions

What is the role of sap in plant defense?

• Attracts herbivores and pathogens

• Provides nutrients for herbivores and pathogens

• Contains chemical compounds that deter herbivores and pathogens

• Has no effect on plant defense

How do digestive juices act as a plant defense mechanism?

• They provide essential nutrients for herbivores

• They emit a pleasant smell to attract herbivores

• They have no effect on herbivores

• They contain toxic compounds that deter herbivores from consuming the plant.

Explain the importance of physical plant defense in the survival of plants.

• Physical plant defense is not important for the survival of plants

• Physical plant defense only protects plants from weather, not herbivores or pathogens

• Physical plant defense is important for protecting plants from herbivores and pathogens, thus ensuring their survival.

• Plants can survive without physical defense mechanisms

Discuss the significance of chemical plant defense in the plant kingdom.

• Chemical plant defense only works against pathogens and not herbivores

• Chemical plant defense has no impact on protecting plants from environmental stresses

• Chemical plant defense helps protect plants from herbivores, pathogens, and environmental stresses.

• Chemical plant defense is used to attract herbivores and promote their feeding
