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 trachelds In the same amount of lime? 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?
To determine: The quantitative statement about the relative amount of spore production of Cryptoporous volvatus per square centimeter in the two samples.
Introduction: Basidiocarp is the structure of the fungi, which contain spores and facilitate the dispersal of the spores on the suitable surface to reproduce. The aggregation of the mycelium hyphae or dikaryotic mycelium constitutes the formation of basidiocarp. The flat surface provides a better dispersal of the spores.
Explanation of Solution
Cryptoporous volvatus is the fungus that produces spores to produce the more daughter cells. The spores, which were produced between June 1 and September 1, under the fir tree, were collected in the stainless steel funnel to make a count for them. The funnel with a surface area of 1.1 cm2 carried 1.31 × 108 spores. Thus, the spores produced in an area of 1 cm are 1.2 × 108 spores.
Another funnel with a surface area of 8.37 cm2 contained 6.87 × 109 spores. Thus, the total spores in the area of 1 cm are 8.2 × 108 spores/cm2. Hence, the quantitative analysis shows that spores that were produced in the funnel with a larger surface area contained approximately six times more spores than the funnel with a smaller surface area.

- Imagine you have a plant with a water potential of -0.1 MPa in the root tissue. What would happen if you place the roots of this plant in a 0.1 M solution of sucrose (water potential is -0.23 MPa)? The net water flow would be from the tissue into the sucrose solution The net water flow would occur only as ATP was hydrolyzed in the tissue The net water flow would be from the sucrose solution into the tissue The net water flow would be in both directions and the concentration of water would remain equal The net water flow would be impossible to determine from the values given herearrow_forwardPart 2 XYLEM PHLOEM Direction: Using the diagram below, explain the concepts of pulmonic and systemic circuit in the human Directions: Using the diagram below, explain the transport system in plants.

Why? What does the weight of the water have to do with this? Stolons, rhizomes, and horizontal vines do not have a problem with the weight of water. Why? In the epiphytic cactus Rhipsalis, the weight of water actually makes conduction easier. Why?arrow_forward
- 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.arrow_forwardin plants , water is transported through vessels called xylem gravity and move water to their upper tissues ?
