Homework Help: Biology

Angiosperms (flowering plants) are the largest phylum in the plant kingdom (Angiospermophyta is also called Anthophyta or Magnoliophyta). 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.

With these anatomical features in mind, do research to find an angiosperm that has modified leaves, stems, roots, or flowers that do not function in the normal manner, or that function in an unusual manner. Identify the angiosperm. Example: A California Barrel Cactus has spines in place of leaves to reduce water loss.
Important: Each person in the class should choose a DIFFERENT plant. Read other students' posts to see what they have selected before posting.
Explain how this structural modification helped the plant adapt to its environment. Make sure the plant you choose is an angiosperm. For example, plants such as pine trees, mosses, and ferns are not angiosperms.
Be sure to compare and contrast your choice to other plants presented by students by responding to their posts, using "Reply to Message."

Well, the first question is telling what it has to be about and the 2nd is telling what needs to be answered in the assignment. Would the mistletoe fall into this category? if so, I would like this to be my plant choice.

You might profit from Writeacher's lesson on "how to search on the internet," displayed here below:

For Internet searching:
http://hanlib.sou.edu/searchtools/
At this webpage, you can go immediately to the search sites (first three columns across the top) -- or even better you can scroll down until you see the section called HOW TO SEARCH THE INTERNET. Those are the links to start with. You'll not only learn how to come up with good search terms, but also how to evaluate the webpages you get as results. Some will be good and others will be garbage. You need to know how to tell the difference.

My favorite way to search is to go to Google's advanced search page http://www.google.com/advanced_search?hl=en and put my search words or phrases into the first or second search box (either "all the words" or "exact phrase").

Learning to use Google or other search engines can save you time and help you learn to find information efficiently. Here are some websites that can teach you how:

... and one to help you judge whether a particular website's information is worth your time:
