BIOLOGY Biology is the study of life -- life in all of its grandeur. From the very small algae to the very large elephant‚ life has a certain wonder about it.

Characteristics of Life Living tings include both the visible worlds of animals and plants as well as the invisible world of bacteria and viruses.On

Photosynthesis is the process in which autotrophs use light energy to convert carbon dioxide and water into glucose. This conversion into chemical energy is associated with the action of the green pigment chlorophyll. Chlorophyll molecules located in the thylakoid membrane of the chloroplasts are arranged into complexes known as photosystems. Each photosystem contains the reaction center complex and is surrounded by light harvesting complexes. The light harvesting complexes are composed of pigment

1. There are two main types of cells‚ prokaryotic and eukaryotic. The connection between the two can be seen right from their prefixes‚ pro meaning before and eu meaning true or good. This is because prokaryotic cells are before a nucleus and eukaryotic cells possess a true nucleus. This has led to many theories that eukaryotic cells have evolved from prokaryotes. The evidence for this is most noticeable in the structure of the cells‚ which will be compared below. Prokaryotic cells have no

Ecological Succession Script Andy Raskita The world around us is slowly and constantly changing. We might never see the small alterations happen‚ but many years later‚ changes will surely be visible. Over time small changes add up and soon the whole ecosystem is different. This slow change in the land and habitat is called ecological succession. Animals‚ plants‚ and weather are some factors that cause this type of change in an ecosystem. Ecological succession begins with a pioneer community. In
