Desert Plants Quiz

Why are the leaves of desert plants modified into spines?

• To attract pollinators

• To reduce water loss and protect against animals

• To store food

• To perform photosynthesis

What is the primary role of the green stem in desert plants?

• To absorb water from the air

• To prepare food through photosynthesis and store water

• To attract animals for pollination

• To convert spines back into leaves

How do desert plant roots adapt to search for water?

• By growing shallow and wide

• By storing water in the root hairs

• By spreading out deeply underground

• By developing thorns

Which combination of adaptations helps desert plants survive extreme conditions?

• Green stems, modified roots, spiny leaves

• Shallow roots, spiny flowers, thick stems

• Deep roots, spiny leaves, fleshy stems with a waxy coating

• Thick leaves, bright flowers, shallow roots

Why is the waxy cuticle on desert plants particularly important in preventing water loss?

• It reduces the rate of photosynthesis.

• It reflects sunlight to keep the plant cool.

• It forms a barrier that minimizes transpiration.

• It stores excess water for later use.
