Unfavorable conditions in the deserts, especially the lack of water, have discouraged many living things from inhabiting these landscapes. Nevertheless, there are exceptionally surviving ones which through their superb tactics, have managed to live through and are still going strong. One such kind is the specialist annual plants which overcome seasonal temperature changes with their extremely short, active life cycles. In events of sudden rain, the plant seeds pullulate and grow very quickly to make full use of the rain water. Their flowers bloom and set seeds that ripen quickly in the hot sun too. Once the water runs dry, the mother plant dies, leaving behind the drought-resistant seeds, waiting patiently for the next rainy season to arrive.
