According to the text and Figure 35.26, why is studying the variations shown in the figure important for understanding Arabidopsis thaliana ?

  • A: It demonstrates the direct agricultural value of *Arabidopsis* as a crop.
  • B: It illustrates different ways *Arabidopsis* cells undergo cell division and enlargement.
  • C: It provides insights into evolutionary adaptations that allowed *Arabidopsis* to expand its range and strategies for crop improvement.
  • D: It highlights the complex biochemical pathways involved in plant development that lead to morphological differences.

Explanation

Figure 35.26 illustrates variations in Arabidopsis thaliana populations. The accompanying text states that 'information in the genomes of these populations is information about evolutionary adaptations that enabled Arabidopsis to expand its range into new environments following the retreat of the last ice age. This information may provide plant breeders with new insights and strategies for crop improvement.'
