The Discussion Board (DB) is part of the core of online learning. Classroom discussion in an online environment requires the active participation of students and the instructor to create robust interaction and dialogue. Every student is expected to create an original response to the open-ended DB question as well as engage in dialogue by responding to posts created by others throughout the week. At the end of each unit, DB participation will be assessed based on both level of engagement and the quality of the contribution to the discussion.

At a minimum, each student will be expected to post an original and thoughtful response to the DB question and contribute to the weekly dialogue by responding to at least two other posts from students. The first contribution must be posted before midnight (Central Time) on Wednesday of each week. Two additional responses are required after Wednesday of each week. Students are highly encouraged to engage on the Discussion Board early and often, as that is the primary way the university tracks class attendance and participation.

The purpose of the Discussion Board is to allow students to learn through sharing ideas and experiences as they relate to course content and the DB question. Because it is not possible to engage in two-way dialogue after a conversation has ended, no posts to the DB will be accepted after the end of each unit.

Angiosperms (flowering plants) are the largest Phylum in the plant kingdom Plantae. (Note that the Phylum Angiospermophyta may also be called Anthophyta or Magnoliophyta in different classification systems.)

These plants have true roots, stems, leaves, and flowers. The roots grow into the soil to anchor the plant in place and take up water and nutrients. The leaves are above ground and act as the main organs for photosynthesis. Stems provide above ground support for the plant and operate as conduits to move nutrients and water throughout the plant. Flowers contain the male and female reproductive organs of the plant.

Assignment details:

With these anatomical features in mind, do research to find an angiosperm species that has structural modifications to leaves, stems, roots, or flowers that result in adaptive functions. For example, a California Barrel Cactus has spines in place of leaves to reduce water loss.

Discuss the following in your answer:

1. Identify the angiosperm species and describe the structural modification.
2. Explain how this specific structural modification (adaptation) to leaves, stems, roots, or flowers helps the plant to live and survive in its environment.

Provide references in APA format. This includes a reference list and in-text citations for references used throughout the assignment.

In your own words, please post a response to the Discussion Board. Be sure to compare and contrast your choice to other plants presented by at least two other students by responding to their posts, using “Reply to Message.” You will be graded on the quality of your postings.

Important: Each person in the class should choose a DIFFERENT flowering plant species. Read other students’ posts to see what they have selected before posting your assignment.
