Chapter 36, Problem 6TYU
Summary Introduction
Introduction: Soil is a thin layer of Earth’s crust. They are in large number where different types of organisms colonize in the soil. These organisms depend upon the soil for their shelter and food. Almost all the essential nutrients, water, and minerals for the growth of plant are directly obtained from the soil. The roots absorb water and dissolved minerals. The dissolved minerals are transported from roots to the leaves throughout the plant in the xylem.

Students have asked these similar questions
Discuss which pathway permits the passage of most solutes and water inside the roots? Which pathway allows the entry of most of the water and some of the solutes inside the root tissue? Explain how the Casparian strip creates a barrier for substance moving through this pathway and how it is circumvented.
Can 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?
Both cohesion-tension and root pressure are mechanisms for moving water in the xylem. What does it mean when it says that cohesion-tension pulls water, but root pressure pushes water?

- Describe how roots absorb positively charged mineral ions by the process of cation exchange.arrow_forwardWhich of the following is true for the function of xylem and phloem? * A. Xylem transports water from leaves to roots; phloem transports sugar from roots to leaves B. Xylem transports sugar from roots to leaves; phloem transports water from leaves to roots C. Xylem transports water from roots to leaves; phloem transports sugar from leaves to roots D. Xylem transports sugar from leaves to roots; phloem transports water from roots to leavesarrow_forwardThe mature regions of roots are relatively impermeable to water. Why? Explain its importance.arrow_forward
- When 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_forwardGiven 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_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
- In the growing root tip, cells elongate considerably. This elongation is driven primarily by uptake of water by the cells and their prominent central vacuoles. How would you investigate the role of aquaporins in the uptake of water in these cells?arrow_forwardWhich one of the following statements about root hairs is CORRECT? Select one: a. They are found in the zone of cell elongation and help the root to fix nitrogen. b.They are found in the root cap and help the root sense gravity. c.They are found in the zone of cell division of the root and help anchor the plant in the soil. d.They are found in the root apical meristem and help the root to absorb water. e.They are found in the zone of cell differentiation in the root. Which of the following best describes the route to fruit formation in flowering plants? Select one: a. 1) pollination, 2) double fertilization, 3) embryo develops, 4) ovary matures, 5) ovule matures. b. 1) pollination, 2) germination of pollen, 3) endosperm develops, 4) ovule develops. c. 1) pollination, 2) endosperm develops, 3) embryo develops, 4) ovule matures. d. 1) pollination, 2) fertilization, 3) embryo develops, 4) ovary matures. e.1) pollination, 2) fertilization, 3) germination of pollen, 4) ovule…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_forward
- What are apical meristems?Which type of plant growthdoes this meristem promote?arrow_forwardWhen farmers apply too much fertilizer to the ground, the solute concentration is higher in the soil than it is in the roots. Explain how this would affect plants. And place these structures in the order that water passes through them during transpiration: endodermis, root cortex, root hair, spongy mesophyll, stomata, and xylem. -Thank you!arrow_forwardWhy is the secondary xylem and phloem always to either side of the vascular cambium? Is the primary xylem pushed inwardly by the secondary tissues? Are the primary phloem, cortex and epidermis pushed outward by the secondary tissues?arrow_forward
