Do plants have phenotypic plasticity?
Phenotypic plasticity is considered one of the major means by which plants can cope with environmental factor variability. Nevertheless, the extent to which phenotypic plasticity may facilitate survival under environmental condition changes still remains largely unknown because results are sometimes controversial.
Why is phenotypic plasticity common in plants?
This means that different leaves could have the same gene but present a different form based on environmental factors. Plants are sessile, so this phenotypic plasticity allows the plant to take in information from its environment and respond without changing its location.
Is Polyphenism an example of phenotypic plasticity?
Polyphenism is a special case of phenotypic plasticity where development exhibits reproducible bifurcations revealing multiple distinct outcomes (e.g., worker vs. queen bee).
What is plasticity of plant?
The ability of an organism to change its phenotype in response to different environments, termed plasticity, is a particularly important characteristic to enable sessile plants to adapt to rapid changes in their surroundings.
How do you measure phenotypic plasticity in plants?
One way to quantify phenotypic plasticity is to use analysis of variance (ANOVA). The idea behind ANOVA is to take a variety of genotypes and a variety of environments and assess the resulting phenotype for each genotype-environment pair.
What is plasticity in plant growth?
Plant plasticity refers to a plant’s ability to adapt to and cope with changes in its environment.
What causes polyphenism?
A polyphenic trait is a trait for which multiple, discrete phenotypes can arise from a single genotype as a result of differing environmental conditions. It is therefore a special case of phenotypic plasticity.
What affects phenotypic plasticity?
For instance, genetic variation originates from individuals that differ by carrying different alleles for relevant genes, phenotypic plasticity results from individuals experiencing different environmental conditions, and developmental instability results from random variation in developmental processes (developmental …
How does phenotypic plasticity occur?
Even though the phenotype is defined here to exclude the genome, in fact phenotypic plasticity always involves a change in gene expression or gene-product use (morphological, physiological, and behavioral traits always being products, in part, of gene expression).
Which of the following is an example of plasticity in plants?
The ability to change under the influence of external and internal stimuli is called plasticity. The intrinsic plasticity is found in juvenile stage of many plants, e.g., cotton, coriander, larkspur. Environmental plasticity is best seen in emergent hydrophytes, e.g., buttercup.
What is plasticity in plant development?
Plasticity gives plants the ability to optimise growth in varied environments. Developmental plasticity comes from the meristem, which continuously produces organs throughout the plant life cycle.
What is plasticity in plants?
In which plants plasticity is induced by different habitats?
Answer: The correct answer is Buttercup.
What is the difference between polyphenism and polymorphism?
Polymorphism is heritable, and is modified by selection (either artificial or in the wild). In polyphenism, an individual’s genetic make-up allows for different morphs, and the switch mechanism that determines which morph is shown is environmental.
What are the two types of polyphenism?
Genetically fixed (non-responsive to environmental conditions) Polyphenic (responsive to environmental conditions)
How do you explain phenotypic plasticity?
Phenotypic plasticity of a trait is variation of the target phenotype for a given genotype in different environments. In particular, a reaction norm characterizes plasticity by describing how the target phenotype for a specific genotype varies as a function of an environmental variable.
