Question
Chapter 36, Problem 8TYU
Summary Introduction
Introduction: The evaporation of water from plant leaves is known as transpiration. In this process, moisture exits from plant through small pores known as stomata, in form of vapor and is released into the environment.

- There is a trade-off between photosynthesis and transpiration in leaves because (a) numerous stomatal pores provide both gas exchange for photosynthesis and openings through which water vapor escapes (b) a waxy layer, the cuticle, reduces water loss (c) blue light triggers an influx of potassium ions (K+) into the guard cells (d) leaves of deciduous plants abscise as winter approaches in temperate climates (e) stomata are closed at night, although water continues to move into the roots by osmosisarrow_forwardWhen absorption of water by the roots fails to keep up with the rate of transpiration, gain in turgor occurs, and the stomata close. A. Agree, because the transpiration occurs faster than root absorption. D. Disagree, because the condition should be when root absorption is able to keep up with transpiration, then stomates close. B. Disagree, because under this condition, the turgor pressure decreases and the stomates close. C. Agree, because increase in turgor pressure under this condition, closes the stomates.arrow_forwardCan you answer this question with both parts a. How does plant growth respond to gravity in stems vs. roots? b. How is gravitropism controlled during root growth?arrow_forward
- Why is the secondary xylem and phloem always to either side of the vascular cambium and is the primary xylem pushed inwardly by the secondary tissues? How about the primary phloem, cortex and epidermis, are they pushed outward by the secondary tissues?arrow_forwardWhat are some of the environmental factors which influence the rate of transpiration? Discuss the advantages and disadvantages of the transpiration process in plants? What strategies have evolved by which plants are able to reduce their transpiration rates and thus conserve water? What tissue/s did you find the dye along the stem?arrow_forwardWhy do plants make such an extensive investment belowground?arrow_forward
- why is pressure higher in parts of the phloem Where sugar is being loaded than in parts were sugars been removed?arrow_forwardPhotosynthesis sustains plant growth, and inputs of sunlight sustain photosynthesis. Why, then, do seedlings that germinate in a fully darkened room grow taller than seedlings of the same species that germinate in full sun?arrow_forwardWhat does hydraulic conductance mean in the following? The hydraulic limitation hypothesis proposes that reduced growth in taller trees is caused by decreased photosynthesis resulting from a decrease in hydraulic conductance promoted by a longer root-to-leaf flow path.arrow_forward
- Given that (a) xylem is located toward the upper epidermis in leaf veins and phloem is located toward the lower epidermis and (b) the vascular tissue of a leaf is continuous with that of the stem, suggest one possible arrangement of vascular tissues in the stem that might account for the arrangement of vascular tissue in the leaf.arrow_forwardWhy does a layer of periderm offer only temporary protection? When the plant makes a new layer of cork cambium, does it make the new layer to the outer side of the failing periderm or to the inner side of it, deeper in thesecondary phloem?arrow_forwardMovement of phloem sap from a source to a sink(A) occurs through the apoplast of sieve-tube elements.(B) depends ultimately on the activity of proton pumps.(C) depends on tension, or negative pressure potential.(D) results mainly from diffusion.arrow_forward
