Imagine you are a botanist.  Below are characteristics of a never-before described plant species recently identified as part of the ‘All Taxa Biodiversity Inventory’ (ATBI).   Field Notes:  Specimen collected from shaded area along stream in South Cumberland State Park                 (Grundy County, TN). Laboratory Analysis:  Body:  Large leaves emerging from underground rhizome. Size: 63 cm  Chromosomal Analysis: Plant body is diploid—chromosome number of 44. Lignin test: Positive Cuticle: Present Leaves:  Present—large with branched veins. Underside has sori (containing haploid spores). Roots: Present—branch from the inside. Stem: Present—vascular tissue (xylem & phloem) present. Life History:  Diploid sporophyte dominant generation.  Haploid spores germinate into heart-shaped, haploid, gametophyte.  Water required for fertilization; no seed is produced.  Diploid zygote develops into sporophyte. Explain which domain, kingdom and phylum you believe this plant should be classified…

Adaptations to a Changing Environment  Why is it necessary for organisms to have the ability to adapt? Why is the current environment making it difficult for organisms like the monarch butterfly to adapt? Explain how organisms develop adaptations.
