A team of researchers is studying the external structures on the dorsal (back) surface of a spider mite. The spider mite seems t
o be the habitat of an even smaller mite, which is approximately 0.05mm. While they can see the dorsal surface of the spider mite with their naked eye, they cannot see the mite clearly. The researchers are writing a grant to provide support for a microscope to use to study these new mites. They need to purchase a microscope with a high magnification to observe the new mites on their habitat. Based on the information given, what type of microscope would you suggest? A. transmission electron microscopeB. scanning electron microscopeC. dissecting microscopeD. binocular compound light microscope
The most appropriate microscope for this research is the binocular composite light microscope, because these types of microscope work by capturing light in a tiny, well-lit area without the need for a large lens. The lens of a microscope is small and spherical, so the image of the object is focused a short distance from the microscope tube. The image is then magnified by a second lens that brings it into the viewer's field of view. Making it possible to view bodies as small as the research mite.
Animal and plant cells both are eukaryotic, contain membrane bound organelles such as mitochondria, ribosomes, Golgi complex, endoplasmic reticulum etc.
Plants cells only differ in the presence of cell wall and chloroplasts.
Centrioles are present in all animal cells but only in some lower plant forms. They produce spindle fibers in cell division. In plants, an organelle called the centrosome generates the spindle fibers.
Lysosomes are also solely present in animal cells. They contain hydrolytic enzymes for breaking down various biomolecules.
Cilia are also present in animal cells but not in plants. Cilia serve in locomotion and transport of materials through cells. In the respiratory system, cilia trap pathogenic microbes and particulate matter.
The organism that has no specialized cell is Paramecium. Paramecium are members of the phylum Ciliophora. They feed on organisms like bacteria, algae, and yeasts . These organisms uses cilia to sweep the food along with some water into the cell after it falls into the oral groove. The food then goes through the cell mouth into the gullet.
