light microscopes
The objective lens is the most important part of a microscope because it magnifies the specimen being viewed. It determines the level of detail and resolution that can be achieved in the image. The quality of the objective lens directly impacts the overall performance of the microscope.
An electron microscope would be most appropriate for studying the internal parts of a cell due to its high resolution and ability to visualize structures at the nanometer level. This would allow scientists to observe details such as organelles and cellular components in great detail.
The nucleus is the most noticeable organelle in a eukaryotic cell under a microscope due to its size and distinct structure. It appears as a large, round structure typically located in the center of the cell.
Most cells are too small to see without the aid of a microscope.
The 100x oil immersion objective is commonly used in microbiology because it provides the highest magnification and resolution, allowing for detailed observation of bacterial cells and other microorganisms.
scanning electron microscope
One of the most powerful instruments to view cells is the electron microscope. It uses a beam of electrons to create high-resolution images of the internal structures of cells, allowing for detailed examination at the subcellular level.

An experiment examining structures smaller than a cell would most likely employ an electron microscope, such as a transmission electron microscope (TEM) or a scanning electron microscope (SEM). These microscopes use electron beams instead of visible light to achieve much higher resolution, allowing for the observation of fine details at the molecular or atomic level. This capability makes them ideal for studying subcellular structures, viruses, and other nanostructures.
It rather depends on how deeply you wish to view the object. An optical microscope is adequate for most studies. But, with an electron microscope, not only could you view a flea in detail, but also the minute hairs on the flea's legs

To examine leaves' veins in greater detail, a microscope would be the most effective tool, as it allows for high magnification and clear visualization of intricate structures. Additionally, a digital imaging system could aid in capturing and analyzing the vein patterns more precisely. A hand lens could also be useful for a quick, closer look at the leaf's surface, but it lacks the detail provided by a microscope.

A dark-field microscope is used to observe translucent specimens that are difficult to see with a conventional microscope. It creates contrast by illuminating the specimen from the sides, causing light to scatter and objects to appear bright against a dark background. This technique is especially useful for studying live microorganisms and subcellular structures.
