making it impossible to grow susceptible bananas in the same location for up to several decades. (2) The disease is resistant to fungicide and cannot be controlled chemically. (3) Page | 1 The fungal pathogens enter the banana tree through the xylem‚ and then use the water stream to spread the fungal spores throughout the entire plant. These spores lodge into the vessel walls and block the water flow‚ causing banana leaves to wilt and die. Panama disease often kills entire banana trees. The fungal

The Effect of Light Intensity on Photosynthesis and Transpiration Inna V. Raymundo BOTANY I Section V-6L August 29‚ 2012 ¹A scientific paper submitted in partial fulfillment of the requirements in Botany I laboratory under Dr. Nonnie Bautista‚ 1st sem‚ 2012-2013. ABSTRACT Photosynthesis and transpiration both play important roles in plants. But there are factors which affect the rate of photosynthesis and transpiration. The external factor that was identified is the

Maintaining a Balance Enzymes 1.1 Identify the role of enzymes in metabolism‚ describe their chemical composition and use a simple model to describe their specificity on substrates Enzymes are biological catalysts‚ meaning they are organic and speed up a chemical reaction without taking part in it. This means it has a vital role in metabolism where it ensures that the chemical reactions that make up metabolism can function fast enough to sustain life by lowering activation energy. Metabolism

types of roots are the taproot system and the fibrous root system; both are crucial for plant growth. Second‚ the stems‚ carry water and nutrients taken up by the roots and carry it to the leaves to be produced into food. Inside the stems are the xylem cells‚ which move water‚ and the phloem cells‚ which move food. Third is the leaves‚ which are the food making factories of the plant. Leaves come in a variety of sizes‚ and can be simple or compound. Photosynthesis takes place in the leaves‚ where

HW Review for Photosynthesis exam: Due Monday March 28 Reminder your lab write up will be a next week. If your lab is this Friday you also will get a week to complete your full lab write-up. Sample questions: 1. twenty-five plants were placed in each of four closed containers and then exposed to light conditions shown in the data table below. All other environmental conditions were held constant for a period of 2 days. At the beginning of the investigation‚ the quantity of CO2 present in each closed

Distinguish between the strategies used by autotrophs and heterotrophs to obtain free energy for cellular processes. In other words‚ how and in what form does each capture and store that energy? 2. Explain how photosynthesis differs in eukaryotic organisms (with organelles such as chloroplasts) and in prokaryotic organisms (single-celled‚ no organelles). 3. How does a metabolic

increase transpiration as greatly as light acting alone. Introduction Plants draw water in through their roots‚ and then transport it through the xylem up to the branches and leaves. Water exits the leaves through the stomata in the form of water vapor. Polarity causes the water exiting through the stomata to draw after it the water in the xylem‚ which then pulls in more water through the roots. This process is known as transpiration (Raven et al.‚ 2002). Transpiration is a vitally important
