PLZ HELP DUE IN 30 MINS

1) Why is having no leaves a good adaptation for plants found in the desert?

2) What is the evolutionary significance of developing pouches? (What makes a pouch a good adaptation?)​

Answer 1

1)The leaves and stems of many desert plants have a thick, waxy covering. This waxy substance does not cover the stomata, but it covers most of the leaves, keeping the plants cooler and reducing evaporative loss. Small leaves on desert plants also help reduce moisture loss during transpiration.
