- Danish is preparing a plate of papaya (Carica papaya) for his sleepover friends. As he cuts open the papaya, they discover great numbers of slime-covered seed inside, surrounded by soft flesh and soft skin. Before papaya fruits ripen and the seeds inside them mature, their flesh is bitter or sour. Only later does it become tasty. Discuss how this feature improves the odds for the plant's reproductive success and identify the possible agents to disperse the seeds.At which temperature pollen grains can be stored for several years in liquid nitrogen?The data that is attached below was collected during a lettuce seed ecotoxicity assay. Lettuce seed assays are used to compare the ecotoxicity of methanol, ethanol, and isopropanol by these alcohols' effects on germination rate and root elongination. Using the attached data, help answer which alcohol seems to be the most toxic to lettuce seeds. Why or why not would your results be expected? What does this information tell you about using ecotoxicity data to estimate human toxicity?
- Which of the following explains why pea plants in high soil nitrogen conditions have so few rhizobial nodules on their roots? When there is already high soil nitrogen there is a very large cost to having rhizobial nodules. The rhizobia bacteria in the nodules fix nitrogen when there isn't enough in the soil, so when there is already high soil nitrogen there is no advantage for the pea plant to expend the extra energy housing the rhizobia. The rhizobia bacteria in the nodules use nitrogen when there isn't enough in the soil, so in conditions of high soil nitrogen the plant tries to exclude the rhizobia to keep the nitrogen for itself. When there is already high soil nitrogen there is no benefit to the plant to having rhizobial nodules, which can rob the plant of the high nitrogen supplies so that the rhizobia bacteria do not have to fix the nitrogen themselves.How to germinate okra, tomato, bitter gourd and cowpea seeds.

Remark: The word count limit is 250 words only, no less than 100 words.A team of researchers investigated the effects of phosphorous availability and light intensity on an angiosperm species. Seeds of the angiosperm were divided into four equal groups. Groups 1 and 2 were exposed to 200 μmol, and Groups 3 and 4 were exposed to 500 μmol. Groups 2 and 4 also received a phosphorous (P) solution. After 20 days, all plants were weighed, and the average dry weight of each group was calculated. The results are in the table below. Group 1(200 μmol, no P) Group 2(200 μmol, + P) Group 3 (500 μmol, no P) Group 4 (500 μmol + P) Average Dry weight (g) 0.8 1.1 1.5 6.2 Describe the effects of light and phosphorous on the growth of the plants in this study.
