You bite into a spinach leaf. Which one of the following is true?
a. You are getting 50% of the protein in the leaf in the form ofribulose 1,5-bisphosphate carboxylase.
b. The major pigment you are ingesting is a carotenoid.
c. The water in the leaf is a product of the light-independentreactions.
d. Any energy from the leaf you can use directly is in the form ofATP.
e. The spinach most likely was grown in an area with a low CO2 concentration.

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.
