The Miller-Urey experiment showed that simple molecules could have arisen abiotically. This chemical experiment included conditions similar to those present on the early Earth, and tested the origin of life under those conditions.
Water (H2O), methane (CH4), ammonia (NH3) and hydrogen (H2) were the chemicals used to produce the results of the experiment, the factors needed for simple life to arise. Given similar conditions on other planets, it's possible that life could arise there as well.

The answer is: the water would not be released from the leaves.
<span>Transpiration is a water loss from a plant in the form of water vapor through small pores on the leaves. Plants take water from a soil through roots and release it into atmosphere through the leaves. This happens due to water gradient from the roots to the leaves. If for any reason transpiration stops, the water could not be released from the leaves, and consequently, the less water will be absorbed from the soil.</span>
