Do plants and animals differ in phenotypic plasticity

This paper compares the flexibility in the nexus between phenotype and genotype in plants and animals. These taxa although considered to be fundamentally different are found to be surprisingly similar in the mechanisms used to achieve plasticity. Although non-cog itive behaviour occurs in plants, its range is limited, while mor-phological and developmental plasticity also occur to a considerable extent in animals. Yet both plants and ani-mals are subject to unique constraints and thus need to find unique solutions to functional problems. A true comparison between the plant and animal phenotype would be a comparison between plants and sessile photo-synthesizing colonial invertebrates. Such comparisons are lacking. However, they would provide important in-sights into the adaptive significance of plasticity in these groups. It is also suggested that a comparison of inflexible traits in these groups would provide an understanding of the constraints, as well as the costs and bene-fits, of a plastic versus non-plastic phenotype in plants and animals.
