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.

- Insect-Assisted Fertilization in Moss Moss sperm can swim, but plant ecologist Nils Cronberg suspected that they sometimes hitch a ride on crawling insects or mites (tiny animals related to spiders). To test this hypothesis he carried out an experiment. He placed patches of male and female moss gametophytes in dishes, either next to one another or with water-absorbing plaster between them. The plaster prevented sperm from Swimming between plants. He then looked at how the presence or absence of insects affected the number of sporophytes formed. FIGURE 22.8 shows his results. FIGURE 22.8 Sporophyte production in female moss patches with and without either crawling insects (springtails) or mites. No Sporophytes formed in the animal-free dishes when moss patches were 2 or 4 centimeters apart Does this study support the hypothesis that insects and mites aid moss fertilization?arrow_forwardInsect-Assisted Fertilization in Moss Moss sperm can swim, but plant ecologist Nils Cronberg suspected that they sometimes hitch a ride on crawling insects or mites (tiny animals related to spiders).

No sporophytes formed in the animal-free dishes when moss patches were 2 or 4 centimeters apart. 1. Why is sporophyte formation a good way to determine if fertilization occurred?arrow_forwardIn 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_forward

The concentrations of some dissolved materials remain virtually constant in the cells of the seaweed.arrow_forwardA mutation causes the vascular cambium in a plant to stop working. How does this impact cellular respiration? The stomata would remain open and release water vapor. The guard cells would remain closed and store water vapor. The leaves would not be able to release glucose for energy production. The xylem would not be able to transport water to the rest of the plant.arrow_forwardPolypodium polypodioides is a type of fern that can withstand extreme dehydration by curling its fronds and shriveling its leaves.
