Connecting Concepts: Plant Biology/Water Relations

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.

Wonderful progression of information. Could see using this for someone who is out sick during this topic.

Pertinencia: Me parece pertinenete ya que integra los diferentes conceptos de potencial asociadoal movimiento del agua en el sistema SAP.  Ademas lo encuentro interesante, desde el punto de vista de ejercitarse para internalizar los conceptos. haria la salvedad de que podria explicarse un poco algunos topicos para una mas rapida comprension.

facilidad de uso y navegacion: Teniendo claro los conceptos es extraordinariamente difacil de utilizar como medio didactico, considerando que se puede tener una comprension de cada instancia  o etapa del proceso de flujo del agua.

Calidad de la informacion:  La calidad de la informacion es de muy buen nivel, clara y didactica.

Technical Remarks:

En general el proceso esta presentado en una forma muy didactica, y entendible para quien maneja conceptos basicos.
