Evergreen needles have a thick outer coating, called a cuticle. Predict how this provides an advantage for photosynthesis. Responses A The cuticle holds in more glucose. The cuticle holds in more glucose. B The cuticle helps keep the tree cooler.The cuticle helps keep the tree cooler. C The cuticle allows for enhanced gas exchange.The cuticle allows for enhanced gas exchange. D The cuticle allows them to retain more water.
D The cuticle allows them to retain more water.
The thick outer coating of the cuticle helps to reduce water loss through transpiration, allowing the tree to retain more water for photosynthesis. This is especially advantageous for evergreen trees in dry or cold environments.
