Chapter 16, Problem 1Q
Summary Introduction

To explain: A generalized life cycle of a bryophyte by means of a simple, labeled diagram.

Introduction: Bryophytes are the small and flowerless green plants that comprise the mosses and liverworts. These do not bear roots but contain rhizoids. These are very important in starting the soil formation on a barren terrain and in maintaining the soil moisture. It aids in the recycling of nutrients in forest vegetation. The three phyla of bryophytes are Marchantiophyta (liverworts), Bryophyta (hornworts), and Anthocerotophyta (mosses).

Summary Introduction

To explain: The reason why life cycle of a moss is referre to as an alternation of heteromorphic generations.

Explain down bellow what happens to the cell in pictures not in words: Decreased pH in mitochondria Increased ATP Decreased pH in cytosol Increased hydrolysis Decreasing glycogen and triglycerides Increased MAP kinase activity Poor ion transport → For each one:→ What normally happens?→ What is wrong now?→ How does it mess up the cell?
1.) Community Diversity: The brown and orange line represent two different plant communities. a. Which color represents the community with a higher species richness? b. Which color represents the community with a higher species evenness? Relative abundance 0.1 0.04 0.001 2 4 6 8 10 12 14 16 18 20 22 24 Rank abundance c. What is the maximum value of the Simpson's diversity index (remember, Simpson's index is D = p², Simpson's diversity index is 1-D)? d. If the Simpson's diversity index equals 1, what does that mean about the number of species and their relative abundance within community being assessed?
