Unlike normal C3 and C4 plants, CAM plants
open their stomata at night, when the relative humidity is higher and transpiration losses are lower.

Most CAM plants
are tropical succulents belonging to families such as the Agavaceae, Bromeliaceae, Cactaceae, and Euphorbiaceae, although a single family may contain both CAM and [C.sub.4] plants.
In the shade, CAM plants
operate in phase III over much of the day (Borland and Griffiths 1996, Skillman and Winter 1997).
Aquatic species in five genera stand out as having acid accumulation that is substantially higher than others and within the range of terrestrial CAM plants
. These include the sporebearing Isoetes (Lycophyta: Isoetaceae) and flowering plants (Anthophyta), both monocots, Sagittaria (Alismataceae) and Vallisneria (Hydrocharitaceae), and dicots, Crassula (Crassulaceae), and Littorella (Plantaginaceae).
The lowest response to higher CO2 levels is usually from the CAM plants
, which include pineapples, agaves, and many cacti and other succulents.
In contrast to the potential response of [C.sub.4] and [C.sub.3] plants, CAM plants
show little response to increasing C[O.sub.2].
