Question

critical thinking and applications

1. why should you always use the low - power objective lens to locate objects mounted on the slide first, even if you want to observe them with the high - power objective lens?

suppose you were observing an organism through the microscope and noticed that it moved toward the top of the slide and then it moved right. in what directions did the organism actually move?

Explanation:

1. The low - power objective lens has a wider field of view, making it easier to locate the object on the slide. Once located, it is then easier to switch to the high - power objective lens for detailed observation.
2. Microscope images are inverted. So, if an organism appears to move towards the top of the slide, it actually moves towards the bottom. If it appears to move right, it actually moves left.

Answer:

1. The low - power objective lens has a wider field of view, which helps in quickly finding the object on the slide before using the high - power lens for detailed observation.
2. The organism actually moved towards the bottom and then left.
