The genotype describes the complete set of genes inherited by an individual, and the phenotype describes all aspects of the individual's morphology, physiology, behavior, and ecological relations. Light, water, temperature, soil structure are the environmental factors which influence the plant phenotype most. The growth is a very sensitive phenotypic trait that quickly responds to any sub-optimal environment. However, many more physiological responses occur that turn out in phenotypes that can be measured with non-invasive technology.
sunlight and nutrient availability
To confirm the above hypothesis, Maria should perform an experiment to prove that xylem is responsible for the transport of coloured water through the plant. This is called the ascent of sap.
A suitable plant having a tender, semitransparent stem should be selected. The root system of the plant should be cut off and the twig has to be placed half-immersed in a coloured solution of water for about one hour. Later, when the plant is observed, parallely running streaks of coloured water can be seen through the semitransparent stem and other parts of the plant indicating that the xylem is involved in the upward movement of water.
Answer:
It should be change in behavior because they moved underground
