The clear epidermal cells exist in a single layer and do not contain chloroplasts, because the onion fruiting body (bulb) is used for storing energy, not photosynthesis. [3] Each plant cell has a cell wall, cell membrane, cytoplasm, nucleus, and a large vacuole. The nucleus is present at the periphery of the cytoplasm.

Radial arrangement of PP-technique (3 or more channels) provides the possibility to compare chemotactic activity of different cell populations or study preference between ligands. [1] Counting of cells: positive responder cells could be counted from the front of migrating cells, after staining or in native conditions in light microscope.
A buccal swab, also known as buccal smear, is a way to collect DNA from the cells on the inside of a person's cheek.Buccal swabs are a relatively non-invasive way to collect DNA samples for testing.
A live-cell microscope. Live-cell microscopes are generally inverted. To keep cells alive during observation, the microscopes are commonly enclosed in a micro cell incubator (the transparent box). Live-cell imaging is the study of living cells using time-lapse microscopy.
In some cases, cells may be grown directly on a slide. For samples of loose cells (as with a blood smear or a pap smear) the sample can be directly applied to a slide. For larger pieces of tissue, thin sections (slices) are made using a microtome; these slices can then be mounted and inspected.
Since Hooke discovered cells, microtechnique had also developed with the emergence of early microscopes. Microtechnique then had advanced over the period of 1800–1875. [6] After 1875, modern micro methods have emerged. In recent years, both traditional methods and modern microtechnique have been in use in many experiments. [3]
