Use the SCANNING (4x) objective to focus. Only one layer of cells is in focus when using the high. Botany Lab Practical Flashcards Quizlet. But after a few minutes of study under the microscope, the bright light and warmth of the lamp encouraged cyclosis and the chloroplasts migrated to the cell walls and started their cyclic motion. A cell was then located which performed cyclosis, and was exposed to the light produced by 1 lamp. Cells Under A Microscope By Jaimarie Nelson.
