Compare the ST and CT treatments in Figure 4 to the other treatments (T1, T2, T3, and T4).  What do the controls show about the experimental treatments? (Choose one.) Group of answer choices Only F. kuroshium and N. metavorans are pathogenic to the fig trees, and disrupt movement of xylem sap through the plants. Conductance of xylem sap is not a good measurement of the degree of fig wilt disease in fig saplings. All of the fungi tested are pathogenic to the fig trees, and disrupt movement of xylem sap through the plants. F. kuroshium by itself is not pathogenic to fig saplings, C. facicola by itself is pathogenic to fig saplings and also interacts with F. kuroshium to disrupt movement of xylem sap through the fig saplings.

Test 3: Microscopic Internal Structure of Stems a. View the images of the Test 3 microscope stem cross-sections of the 4 plant species the images show cross sections through stems of Botana curus and Species X, Y, and Z. Compare the arrangement (circular or scattered) of the bundles of conducting tissue in the specimens. (see Test 3 images-Microscopic Internal Structures of Stems) Refer to Figure 1 to help you determine if the images are scattered or circular.

Do plants produce eggs and sperm through mitosis or through meiosis?Briefly explain your reasonin Why are plant life cycles often described as showing ‘Alternation of generations’?

What is the most likely consequence of a mutation that would cause sporopollenin to degrade quickly right after it is synthesized? -A reduction in the ability of pollen and spores to survive intact and disperse to new areas. -A reduction in the ability of pollinators to detect and transfer pollen grains to a stigma. -A decrease in the number of sperm that can be produced. -A decrease in the ability of the pollen grain or spore to open when a suitable location is found. -A reduction in the ability of the integument of an ovule to develop into a seed coat.

The division of labor among various types of cells in plants is important. As shown, and name the cells responsible for the following tasks:a. Collecting solar energyb. Transporting waterc. Cell division and the production of new protoplasmd. Water retentione. Having pigments that attract pollinatorsf. Producing poisons that inhibit animals from harming the plants

Question 1 Which of the following statements describes the semi-dwarf wheat varieties developed in the Green Revolution? Their harvest is easier with heavy machinery. O They were bred for lodging sensitivity, which is an advantage in the field. As they are shorter, grain heads can touch the ground and give the plant more stability. These plants need more time to make enough carbohydrates to grow.

Why did plant physiologists propose the existence of a mobile molecule(florigen) that triggers flowering?

QUESTION 10 Which is true regarding plant reproduction?     Self-pollination produces offspring genetically identical to the parent     modified organs, such as corms and bulbs, are produced as a result of sexual reproduction     cross-pollination allows plant populations to survive in unstable environments     plants do not reproduce asexually     vectors such as flies carry plant spores to new locations

Based on this evidence, is it likely that burdock would reproduce as much if it didn’t have specially structured seeds? (a) it is most likely that it would still reproduce, but the offspring would probably be located much closer together (b) there is not enough information to speculate about how well burdock plants reproduce (c) no, there wouldn’t be as much burdock without its special structures (d) Yes, burdock would spread just as well regardless of the design of its seed pods
