Video and still pictures of various types of eukaryotic and prokaryotic cells are included. A great animation on how bacteria grow and divide is an added plus for this site. http://www.merlot.org/merlot/viewMaterial.htm?id=90956 A compendium of thousands of pictures of plants and plant structures organized phylogenetically. This collection covers most aspects of botany. http://www.merlot.org/merlot/viewMaterial.htm?id=90119 An introduction to the world of plants from an evolutionary perspective. This site is a supplement to a University of West Indies intorductory botany course. the site is very well illustrated with lots of examples of different plant groups drawn from the West Indies flora. also includes lab handouts, exam questions and numerous links to other botanical sites. http://www.merlot.org/merlot/viewMaterial.htm?id=83578 This tutorial/simulation consists of three topics. In topic 1, students investigate water potential in various, real-life situations. They review components of the water potential equation with the help of “Professor Waterman”. Students will: 1) get descriptions of solute and pressure potential and the water potential equation; 2) learn how to predict the movement of water under various conditions; and 3) gain experience using the water potential equation, and gain familiarity with the associated terminology. In topic 2, students follow movement of water through a plant from the soil to the atmosphere. They calculate water potential at each of 5 locations in the soil-plant-atmosphere continuum. Students will: Students follow movement of water through a plant from the soil to the atmosphere. They calculate water potential at each of 5 locations in the soil-plant-atmosphere continuum. Students will: 1) predict the value and direction of the solute potential and pressure potiential in different parts of a plant, given information about physical conditions; and 2) calculate the water potential for soil, root cell, xylem, mesophyll cell, leaf air space, and atmosphere. In topic 3, students help a restoration ecologist choose plants that will grow at Alamitos Creek, California, based on plant adaptations for dry conditions and the concept of water potential. Students will: 1) complete a simulated applied research project in which they review concepts pertaining to plant adaptations for dry conditions, construct a checklist of criteria for plants adapted to grow at Alamitos Creek, and select 3 plants that meet criteria for growth at Alamitos Creek using inventories of real data for 9 plants. http://www.merlot.org/merlot/viewMaterial.htm?id=90780 Woods simulates growth and competition among three species of trees of the northeastern United States. The user may manipulate various growth and reproductive parameters and then oserve the effects on the community. http://www.merlot.org/merlot/viewMaterial.htm?id=75865 Tutorials on energy conversions, cellular respiration, photosynthesis, proteins, DNA, RNA, DNA replication, protein synthesis, and mutation. Complete with illustrations and animations. http://www.merlot.org/merlot/viewMaterial.htm?id=80033 Interactive animated tutorial that demonstrates photosynthesis, develops understanding of the organelles and compounds at work, describes the light and dark reactions and photorespiration.From the e-book Interactive Concepts in Biochemistry by Rodney Boyer, Copyright 2002, John Wiley & Sons Publishers, Inc. http://www.merlot.org/merlot/viewMaterial.htm?id=77780 This site is designed to make identification of bryophytes, fungi, lichens, slime molds and some primitive plants more colorful and interesting. It has some very interesting pop-up definitions and pictures for identification. http://www.merlot.org/merlot/viewMaterial.htm?id=79743 This is a flash animation of the light dependent reactions of photosynthesis produced by Dr. John Gianini at St. Olaf College. It is part of a set of Biological Animations.
