Chapter 1.2, Problem 3CYU
Summary Introduction
To review:
The level of structural organization, which is typical to a cytologist’s field of study.
Introduction:
Complex living organisms (such as human beings) have various levels of structural organization. The levelsof the structural organization include the chemical level, the chemicals interact with each other to form cellular level, and the cells when put together perform complex functions and form tissue level. The structural complexity adds on to form organ level, organ system level, andorganismal level.

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.
