We certainly saw plenty of cactuses (aka cacti) on our trip to Nevada. It is fascinating the number of adaptations they have to survive/thrive in the desert. They are able to absorb and store large amounts of water. They do not have true leaves, but have spines which are actually modified leaves. These spines also serve to deter herbivores. Photosynthesis occurs in the stems. Transpiration, during which carbon dioxide enters the plant and water escapes, does not take place during the day at the same time as photosynthesis, but instead occurs at night so as to limit water loss.
We can trust that God has similarly prepared us for the environment we are planted in, from desert to rain forest.
