Precipitation—in the form of dew in the warmer months and frost in the colder ones—often forms on grass and leaves during the night. But since this precipitation results from a change between surface and atmospheric temperatures, how can similar water droplets also appear on some houseplants? The answer is that some globules are the result of guttation. Occurring only in vascular plants, guttation begins when water moves from saturated soil into drier plant roots. Water accumulation in roots creates pressure, which, in daytime, is offset through evaporation. At night, however, these plants use the pipe-like elements of their tissue to draw the excess water upwards and push it out the tips of their leaves.
Considering all that apply
There is sufficient evidence in the passage to support which of the following inferences about guttation?
❑ Guttation is more likely to occur in climates that have only rainy and dry seasons, as opposed to ones with four distinct seasons ranging from winter to summer.
❑ Analyzing the quantity of moisture in the soil and the type of plant one were dealing with would be inadequate to determine whether certain droplets were the result of guttation or were simply dew.
❑ In arid climates, guttation is not likely to occur under natural conditions.
In the passage, vascular most nearly means
A. containing channels
B. needing excessive moisture
C. needing little sunlight
D. absorbent
E. suitable for moderate climates

EXPLANATION QUESTION #1
B and C
Choice (A) is incorrect because the passage says that guttation occurs only in vascular plants, and there is no discussion of the difference in the number of vascular plants that exist in the two climates mentioned. Choice (B) is supported because the text says that dew results from a change between surface and atmospheric temperatures. Therefore, an analysis that does not factor in those measurements would be inadequate, as this answer indicates. The described analysis is also inadequate because the passage provides no information on which process is more likely to occur, given that the conditions for both exist. Choice (C) is supported because the passage says that guttation begins when water moves from saturated soil. In an arid climate, the soil is not likely to be saturated with moisture. The phrase under natural conditions in (C) should eliminate exceptions, such as irrigation systems, when considering this choice.

EXPLANATION QUESTION #2
A
In the last sentence, the plants are described as having pipe-like elements that enable the process of guttation to take place. Containing channels in (A) is a good synonym for this description. Choices (C) and (E) may seem plausible, given the reference to houseplants. However, there is no proof that all houseplants are vascular plants, or vice versa. Furthermore, houseplants do not necessarily receive only little sunlight, nor do they necessarily have a moderate climate in which to grow. Choice (B) is incorrect because you know only that the plants take in the moisture, not that they need it, and (D) is incorrect because the plants actually push out the moisture, instead of absorbing it.
