Question 1:

Which of the following is an example of a plant adaptation to reduce water loss?

Explanation: A reduced cuticle thickness is an example of a plant adaptation to reduce water loss. The cuticle is a waxy layer on the surface of leaves that helps prevent water loss. A thinner cuticle allows for more efficient gas exchange while reducing water loss. Therefore, option C is correct.

Question 2:

Which of the following is a plant adaptation for pollination by wind?

Explanation: Producing lightweight pollen is a plant adaptation for pollination by wind. Wind-pollinated plants produce large quantities of small and lightweight pollen grains that can be easily carried by the wind to reach other plants for fertilization. Therefore, option D is correct.

Question 3:

Which of the following is an example of a plant adaptation to survive in arid environments?

Explanation: Developing a deep root system is an example of a plant adaptation to survive in arid environments. Deep roots allow plants to access water stored deeper in the soil, increasing their chances of survival in dry conditions. Therefore, option A is correct.

Question 4:

Which of the following plant adaptations is associated with fire-prone ecosystems?

Explanation: Developing thick bark is a plant adaptation associated with fire-prone ecosystems. Thick bark helps protect the inner tissues of plants from the intense heat of fires, increasing their chances of survival. Therefore, option A is correct.

Question 5:

Which of the following is an ecological significance of plant adaptations?

Explanation: An ecological significance of plant adaptations is supporting biodiversity. Plant adaptations contribute to the diversity and survival of plant species, which, in turn, provide habitats and resources for numerous other organisms. Therefore, option C is correct.
