C4 plants conserve water by?
opening their stomata and admitting C02 only at night
What happens to ordinary plants (or C4 or CAM) when stomata close?
Blah
Where are c4 plants found?
C4 plants are most likely to be found in climates with high temperatures and intensive amounts of sunlight. They are mostly found in these types of climates because C4 plants does not go through photorespiration (a process that goes against photosynthesis) and are able to keep their stomates closed for longer periods to stop large water loss.
In what climates do C4 and C3 fixation happen more efficiently?
In hot, arid conditions, C3 and C4 plants have to partially close their stomata to reduce water loss. However, this inhibits photosynthesis. Therefore, C3 and C4 plants are photosynthetically more efficient in more temperate environments.
What do c3 and c4 plants have in common?
C3 and C4 plants are named after the number of carbon molecules in the first products of their carbon fixation cycles. C3 plants produce 3-phosphoglycerate and C4 plants produce Oxaloacetate.

C4 plants occur more commonly in desert conditions because?
they can fix carbon at the lower CO2 concentrations that develop when the stomata are closed
What happens to ordinary plants (not c4 or can ) when stomata close?

How does CO2 get into a leaf?
Through the stomata, openings in the leaf surface. By diffusion. There are three photosynthesis processes, C3, C4, and CAM. (These names describe part of the chemistry.) The desert plants (and some epiphytes) use CAM, for in this process, the stomata are closed during the day, and open at night. The plant absorbs CO2 into its system as a complex chemical (the CAM bit) over night, and during the day, the stomata close and the plant converts the CAM chemical into CO2 to be used for photosynthesis in the usual way. Normal plants open their stomata during the day, and CO2 diffuses in and O2 out.
When are the stomata of leaves usually open?
Depending on the environment of the plant, stomata will open and close at different times. In hot, dry environments stomata will open around dusk and dawn to minimise water loss. In Wet environments stomata will open during the day as needed
What kind of a leaf has a special design for a special function?
1. The Blechnum family of ferns have a special form for the fronds that carry fertile spores. Conspicuously different from the normal fronds.2. The plants that use the C4 process for photosynthesis use a design in which the stomata are closed during the day, and open at night.3. Some plants have leaves that are unattractive to browsing animals. Gorse is one of these.

What would be the expected effect on plants if the atmospheric co2 concentration was doubled?
Since C4 plants need for CO2 is more than C3 plants, doubling the concentration of CO2 will have more positive effect on C4 plants. If CO2 is a limiting factor for photosynthesis, both C3 & C4 plants will have positive effect.
