Detailed explanation-1: -1. Compound or Stereo Microscope ? Compound microscopes generally have 3-5 objective lenses to magnify objects from 40x to 400x, and some can go up to 1600x magnification. Thus, the microscope is suitable for observing tiny organisms and cells, such as bacteria, pond scum, blood samples, and water organisms.
Detailed explanation-2: -NARRATOR: An optical microscope can magnify a drop of pond water by hundreds of times. It reveals a bustling community of single-celled organisms.
Detailed explanation-3: -Microorganisms in pond water identification can be carried out using a light or an electron microscope.
Detailed explanation-4: -Bright field microscopy is used to view fixed specimens or live cells.
Detailed explanation-5: -In contrast, dark field microscopy should be used for unstained samples like wet mounts. Dark field microscopy increases the contrast to help visualize unstained objects like cells, reducing the amount of light that is passed through the microscope in the process.
