Question

Think about the function of the leaf structure shown in the diagram. What kind of plant is more likely to survive if the amount of carbon dioxide in the air decreases?A. A plant that has many of these structures on every leaf.B. A plant where these structures can close tightly.C. A plant where these structures absorb more oxygen.D. A plant that does not perform photosynthesis.

Answer 1

The decrease transpiration will produce less cooling of the leaves and therefore there will be rising of leaf temperature. The decreased CO2 concentration inside the leaves and the increased temperature of leaf will aid the wasteful process of photorespiration.

Plants need atmosheric CO2 to produce food. But if the amount of CO2 in the air decrease, the plant that can survive are the non-photosynthesic plants which lack chlorophyll or lacking a functional photosystem that gets all of its food from the fungi that it parasitizes.

D. A plant that does not perform photosynthesis
