Summary Introduction

To discuss: The structure of roots with secondary growth.

Introduction: The underground branching root systems are often more extensive than the aerial part of the plant. The extension of root depth and the spread of a plant differ from that of another plant species, and they also vary among individuals of the same species. For the survival of plant, firm anchorage is essential, so that the stem remains upright, enabling the leaves to absorb sunlight efficiently. The roots absorb water and dissolved minerals. The dissolved minerals are transported from roots to the leaves throughout the plant in the xylem.

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…
