- 1) Consider the two titles below, both relating to the same experiment: • "Environmental controls of transpiration" • "Humidity decreases, while light increases, transpiration rate of Phaseolus plants" Which of the two titles is more effective? What makes that title more effective than the other option?Purpose: To determine the effect of varying fertilizer brands upon the growth rate of a vinca plant. What are the independent and dependent variables in this experiment?Friority Standard #2-Use the Scientific Method to desigh I Investigate a phenomena in biology. As an introductory lab in biology class, Mr. Schoder has you conduct an experiment to practice using the steps of the scientific method. Each group will be given 3 planting kits which include pots, sol and seeds. Students are going to plant their seeds and grow their plants for the first week. Once the first week has passed and the seeds have sprouted, groups are going to divide their planters into three groups, one group of plants will receive OmL of water per day. another will get Sml of water per day and the third will receive 10ml of water per day. Students will measure and record the height of the plants once a week for 6 weeks. During the experiment the students found that after the 6 week period the plant that received Oml of water died and had a height of Ocm. The plant that received 5ml of water per day reached a height of 50cm and the plant that was watered 10mL of water per day…

- discuss the major biochemical and physiological considerations the acclimatization of in vitro derived planting materialsMA Demonstrations 1. Transpiration and vascular transport Time celery put in eosin dye solution Time color reached leaves How did the dye get to the leaves? Be specific,Part F - How to determine transpiration rates by the whole plant method Which of the following best explains why the plant in front of the fan lost more mass than the control plant in normal room conditions? The leaves of the plant in front of the fan had the highest initial water potential and therefore lost the most water. The control plant had lower initial water potential in the root area and therefore lost less water. The control plant had a lower initial mass and so lost water at a decreased rate. The fan rapidly moves water molecules away from the leaf surface, lowering the water potential.
