Think about the extreme conditions found in desertsHot temperaturesLack of water for long periods of timeVulnerable to animals
Think about the characteristics of these plants:Small leavesSpikesLarge stem Large roots Waxy cuticle
Connect the characteristics to the conditions to show how they have adapted:small leaves - enables a reduced surface area so the plants lose less water in the heatSpikes - Prevent animals eating them for waterWaxy cuticle - reduces water loss through a lack of evaporationLarge stem - collects and stores water so can last a long period of time without waterWidespread roots - collect water from a large area
