Then switch to 40x and draw one cell and label it.

types has its own special function. The different cells communicate and cooperate with each other to accomplish all the functions that our bodies need. Most cells are very small, so we need to use a microscope to see them. In this lab, we will be using a microscope to look at different types of cells.

Cut the tip 5 to 8 mm from the tip of the freshly sprouted root. Discard the rest of the root. Place the cut tip on a clean microscope slide.Onion cell and cheek cell both are eukaryotic cells as they have a distinct nucleus. An onion cell is a plant cell that has an outermost rigid cell wall and a large vacuole. They appear brick-like in shape. On the other hand, a human cheek cell is an animal cell having a rounded structure but lacking a cell wall. So, the correct answer is 'False'.The epidermis tissue is composed of cells of relatively uniform size and shape (Fig. 1) so the tissue acts like a one-dimensional transmission diffraction grating. The diffraction patterns generated when a laser beam passes through the tissue (Fig. 2) are analyzed and an estimate of the average width of individual onion epidermal cells is …
