is the driving force for water movement through the xylem adhesion cohesion theory 20 What are the physiological processes anatomical structures and mechanisms involved in transpiration 21 What environmental factors affect the transpiration rate Mineral Nutrition Study Guide Questions 1 Name each macro and micro essential element and provide one physiological reason that this element is considered essential to the plant 2 What are the deficiency symptoms for each essential element Be able to identify and describe 3 Why is pH important in nutrient uptake by the roots 4 How does plant nutrition relate to overall plant growth 5 Where does most nutrient uptake occur along the root 6 Why are mycorrhizae important to nutrient uptake and plant growth 7 Why are plants important to mycorrhizae 8 Describe nutritional studies including different hydroponic systems as well as identify and describe Hoagland Solutions Solute Transport Study Guide Questions 1 How do ions move from cell to cell 2 What are the two types of ion transport and how do each work 3 There are two types of proteins that help movement of ions across membranes carriers and channels What is the difference between these two and how does active and passive transport relate to each 4 What is the proton motive force 5 What is the electrochemical potential gradient Water potential of the symplast is higher less negative outside the endodermis than apoplastic water movement inside the endodermis which helps to maintain root pressure Why Water moves from a lower water potential to a more negative water potential and thus root pressure is maintained by the flow of water towards the xylem Select one True False Feedback The correct answer is False Question 2 Partially correct Mark 3 00 out of 4 00 Flag question Question text Complete each statement by matching the correct word to fill in the blank Mycorrhizae are that colonize roots in a symbiotic relationship Mycorrhizae are composed of fine tubular filaments called which form the body of the fungus called the mycelium There are two types have a thick sheath around the roots and penetrate between the cortical cells surrounding them in what is called a Hartig net Answer 1 fungi Answer 2 hyphae Answer 3 ectotrophic The second type do not form a sheath around the root but penetrate into the cells of the cortex and form oval structures called vesicles and branched structures called arbuscules Answer 4 endotrophic Feedback The correct answer is Mycorrhizae are that colonize roots in a symbiotic relationship fungi Mycorrhizae are composed of fine tubular filaments called which form the body of the fungus called the mycelium hyphae There are two types have a thick sheath around the roots and penetrate between the cortical cells surrounding them in what is called a Hartig net ectotrophic The second type do not form a sheath around the root but penetrate into the cells of the cortex and form oval structures called vesicles and branched structures called arbuscules A hydrogen bond is formed when a hydrogen atom is shared between at least water molecules creating electrostatic attractions resulting in very strong intermolecular interactions vesicular arbuscular Question 3 Incorrect Mark 0 00 out of 1 00 Flag question Question text Select one A 1 B 2 C 3 D 4 Feedback The correct answer is 2 Question 4 Correct Mark 1 00 out of 1 00 Flag question Question text Select one True Enzymatic reaction rates vary depending on concentration of substrate and enzyme A single cell layer thick sometimes with a waxy coating best describes the The correct answer is True False Feedback Question 5 Incorrect Mark 0 00 out of 1 00 Flag question Question text Select one A Xylem B Cork Cambium
