6. Tim is observing xylem vessel elements under the microscope. He initially used the low power objective (LPO) to search for the vessel elements formed in his specimen (Fig.3 A), he. He then wanted to see the vessel elements in greater detail, so he used the high power objective (HPO). Although he didn't have any trouble in resolving the vessel elements using the HPO he wanted to try using the oil immersion objective (OI0). He noticed that he needed to use the fine adjustment knob to focus at two different groups of vessel elements one at a time (Fig. 5 B and C). He also noted that he cannot completely resolve the specimen under the O10 when it should appear clearer as shown by his instructor previously. A B Figure 5. Vessel elements developed from cassava pith in response to synthetic plant hormones under LPO (A) and OIO (B and C). a Explain why Tim can only focus on one group of vessel elements at a time when he used

Vessel elements developed from cassava pith in response to synthetic plant hormones under LPO (A) and O10 (B and C). a. Explain why Tim can only focus on one group of vessel elements at a time when he used the O10. (Explain in 2 sentences max) b. Give a reason why Tim cannot completely resolve the specimen under the O10 compared to what was shown by his instructor.
