Question

Write one difference between onion cell and cheek cell. Why is glycerin used to prepare a temporary mount?

Answer 1

Human Cheek Cell. As in all animal cells, the cells of the human cheek do not possess a cell wall. A cell membrane that is semi-permeable surrounds the cytoplasm. Unlike plant cells, the cytoplasm in an animal cell is denser, granular and occupies a larger space.

glycerin used to prepare a temporary mount because, It avoids the drying of the specimen. Besides, glycerine tends to reflect light due to its refractive nature. As a result of it, image appears clearer under the microscope. Due to these reasons, glycerine is used while preparing temporary mount of leaf peel.
