Chapter 36, Problem 3DA

Data analysis Comparative analyses of fossil and extant vascular plants reveal that the maximum diameter for a tracheid is 80 µm. Vessels, however, can reach diameters of up to 500 µm in diameter. How much more water could the largest vessels transport compared with the largest tracheids in the same amount of time? Your calculations are for an Ideal situation. In the context of a growing plant, what other factors would affect the rate of transport through the tracheids and vessels?

This is about vegetative organs in Botany course. In what groups and in what conditions are root hairs absent in root systems of plants? Why are root hairs not formed at the region of elongation and after the region of maturation? Briefly explain why growth in plants is said to be indeterminate. Is there a significance of compound leaves relative to strong winds? How about leaf-eating animals? Justify your answer.
Cottonwood trees are commonly found along river banks and irrigation ditches. They have broad flat leaves and can transpire 200 gallons of water per day. Many succulent plants live in hot, arid environments and have thick leaves with a wax-like substance covering their leaves. They generally open their stomata for gas exchange at night. Using your understanding of transpiration, find the adaptations that allow these plants to survive in their respective environments.
In plants, water is transported through vessels called xylern. The cohesiveness of water molecules allows them to travel up the walls of the vessel. However, for most plants this is not enough to move the water all the way to the top of the plant. How do plants overcome the force of gravity and move water to their upper tissues ? Root hairs push water through the roots and up into the xylem. Plants absorb water through transpiration to supply their upper tissues with water . С The guard cells surrounding the stomata expand and contract, pushing water through the xylem. Water escapes from the leaves through transpiration, creating a vacuum which pulls water up the xylem.
