angiosperm reproduction

What are two characteristics unique to angiosperm reproduction? And how can you tell that grass flowers are wind pollinated rather than insect pollinated?

MONOCOT v. DICOT

I am trying to understand the difference between a typical dicot flower AND a typical monocot flower. I've been searching for a simple to understand drawing that labels the sepal, stamen, pistil (dicot) and also a drawing that labels the typical monocot flower that labels the tepals, stamen, and pistil.

The difference between a woody dicot and a herbaceous dicot.

Describe how a woody dicot stem differs from an herbaceous dicot stem and list a few examples of each.

life on earth (biological concepts from the non-science major perspective)

More than a century ago, French biochemist Louis Pasteur described a phenomenon, now called "the Pasteur effect,' in the wine-making process. He observed that in a sealed container of grape juice containing yearst the yeast will consume the sugar very slowly as long as oxygen remains in the container. As soon as the oxygen is gone, however, the rate of sugar consumption by the yeast increases greatly and the alcohol content in the container rises. Discuss the Pasteur effect on the bases of what you know about cellular respiration and fermentation. the question is taken from 'Applying the Concepts' Chapter 7, Question #3, page 106, textbook 'Life on Earch' by Audesirk, Audersirk, and Byers... click for more
