What you’ll learn

Catch what little fallsExplain how desert plants capture and store rare water pulses with roots and succulent tissue.Storms, fog, and groundwater are opportunistic sources. Root architecture and fleshy storage turn brief wetness into lasting reserves.
Lose almost nothing by dayDescribe stomatal thrift, CAM photosynthesis, and surface defenses that cut water loss.Closing stomata in heat, fixing carbon at night via CAM, and waxy or spiny surfaces keep banked water from evaporating.
Wait for the right rainConnect seed dormancy, ephemeral life cycles, and nurse microclimates to desert timing.Seeds wait for real moisture signals; annuals race a short wet window; shade and site choice protect the young.

Questions this course answers

What is the core water-saving move in CAM photosynthesis?

CAM plants take in CO₂ at night when water loss is lower, store it as organic acids, then run daytime sugar chemistry with stomata closed.

Match each trait to its desert job

Capture, storage, and reduced loss work together: roots grab pulses, tissue banks them, surfaces throttle leakage.

Order a simplified desert annual life sequence after a real rain pulse

Ephemerals compress life into a wet window, then park the next generation as dormant seed.
