The three-domain system is a biological classification that divides cellular life forms into archaea‚ bacteria‚ and eukaryote domains. It emphasizes the separation of prokaryotes into two groups‚ called Bacteria and Archaea. These two groups and eukaryotes each came from separate ancestors with poorly developed genetic make-ups. This classification system recognizes the fundamental divide between the two prokaryotic groups. Archaea appear to be more closely related to eukaryotes than they are to

for optimal growth. Introduction Plants are able to convert light energy into chemical energy through the process of photosynthesis (Campbell & Reese‚ 2005). This process is dependent on both abiotic and biotic factors. Since plants are autotrophs‚ the most vital are abiotic factors such as light‚ temperature‚ wind‚ water‚ and atmospheric gases (Campbell & Reese‚ 2005). The plant of interest in this study is Lemna minor. Duckweed is a small aquatic watering plant that inhabits fresh water

Dennis Carrasco 11-20-12 Introduction For this project we had to experiment to see the effects of blue light on a plants growth. We had to research on light and its effects on photosynthesis. This helped me with my experiment because I had knowledge for what was going on with the plants and light. For this project I and one of my classmates had to conduct a experiment to see the effects of blue light versus white light. For this project we had to grow lentil beans under white and blue light and

Species may affect each other through intermediaries such as shared resources or common enemies.
