Which type of microscope should the students select to view the surface of the leaf?

To view the surface of a leaf, students should use a scanning electron microscope (SEM). Here’s why:

1. Surface Detail: SEM is specifically designed to provide detailed images of the surface of specimens. It uses a focused beam of electrons to scan the surface and create high-resolution images that reveal fine surface structures and textures.
2. High Magnification: SEM offers much higher magnification than light microscopes, allowing students to observe minute details on the leaf surface, such as trichomes (hair-like structures), stomata (pores), and cell textures.
3. Three-Dimensional Images: SEM produces three-dimensional images, which can help in understanding the topography and surface features of the leaf.

For a more accessible option, if a SEM is not available, students can use a light microscope with a high magnification objective lens (such as a 40x or 100x objective). While it won’t provide the same level of detail as SEM, it can still be useful for observing general surface features of the leaf, especially if combined with techniques like surface staining or using a scanning technique like surface scanning microscopy.
