Question

in humans, one function of the skin is to prevent water loss. skin releases water or holds in water when necessary. which two structures in plants have a similar function to skin?
roots and chloroplasts
phloem and roots
cuticle and stomata
stomata and phloem

Explanation:

• Cuticle: A waxy layer on the surface of plant leaves and stems that reduces water loss, similar to how skin holds in water.
• Stomata: Pores on the leaf surface that can open to release water vapor (transpiration) or close to prevent excessive water loss, analogous to skin's ability to release or hold water.
• Roots: Absorb water from the soil, not directly related to preventing water loss like skin.
• Chloroplasts: Involved in photosynthesis, not water - loss prevention.
• Phloem: Transports organic nutrients, not related to water - loss prevention.

Answer:

cuticle and stomata
