- I meant monggo seeds as in Mung seeds (Vigna radiata)A giant puffball (FIGURE 23.13C) produces trillions of spores that disperse on wind. A stinkhom (FIGURE 23.13D) makes fewer spores and they are dispersed by insects. How are these differences analgous to differences in pollen production and dispersal among plants? C Giant puffball D Stinkhom FIGURE 23.13 Diverse club fungus fruiting bodies (basidiocarps)Whos the Pollinator? Massonia depressa is a low-growing succulent plant native to the desert of South Africa. The dull-colored flowers of this monocot develop at ground level, have tiny petals, emit a yeasty aroma, and produce a thick, jellylike nectar. These trails led researchers to suspect that desert rodents such as gerbils pollinate this plant. The researchers trapped rodents in areas where M. depressa grows and checked them for pollen (FIGURE 29.7A,B). They also put some plants in wire cages that excluded mammals, but not insects, to see whether fruits and seeds would form in the absence of rodents (FIGURE 29.7C). A The dull petalless, ground-level flower of Massonia depressa are accessible to rodents, who push their heads through the stamens to reach the nectar at the bottom of floral cups. Note the pollen on the gerbils snout. B Evidence of visits to M. depressa by rodents. Mammals allowed access to plants Mammals excluded from plants Percent of plants that set fruit 30.4 4.3 Average number of fruits per pant 1.39 0.47 Average number of seeds per plant 20.0 1.96 C Fruit and seed production of M. depressa with and without visits by mammals. Mammals were excluded from plants by wire cages with openings large enough for insects to pass through. Twenty-three plants were tested in each group. FIGURE 29.7 Testing pollination of M. depressa by rodents. How many rodents were captured? Of these, how many showed some evidence of ingesting M. depressa pollen?

- Volatile Secondary Metabolites in Plant Stress Responses In 2007, researchers Casey Delphia, Mark Mescher, and Consuelo De Moraes (pictured at left) published a study on the production of different volatile chemicals by tobacco plants in response to predation by two types of insects: western flower thrips and tobacco budworms. Their results are shown in FIGURE 30.19. FIGURE 30.19 Volatile (airborne) compounds produced by tobacco plants in response to predation by different insects. Plants were untreated (C), attacked thrips (T), mechanically wounded (W), mechanically wounded and attacked by thrips (WT), attacked by budworms (HIV), or attacked by budworms and thrips (HVT). Values are in nanograms/day. Which treatment elicited the greatest production of volatiles?Heliotropism may be related to ________ a. photo tropism b. gravitropism c. photoperiodism d. a and c
