Wait a few seconds for the dye to penetrate into the sample, then rinse by adding water to the slide and either soaking up or draining off the excess liquid. This is a consequence of mitotic cell division—which produces genetic clones and contributes to the development of specific tissues, each made up of distinct cell types with distinct functions (in this case, inner epidermal cells). Vessel elements evolved in the most recent group of plants, the Angiosperms, and are usually much wider than tracheids. %%EOF They have little holes that let out extra water the plant is done using, so more water can come rushing up.

In this lab, they looked at the mitochondria of celery under the microscope after adding sucrose solution and then adding a dye that is only colored when in an oxidized state. Observe an onion cell under the microscope. You will find collenchyma cells in dense clusters near the epidermis in a region called the cortex, forming the strings that you would find in your celery. Under the intense radiation of the electron microscope (0.1–1 electron per Å 2), the question of viability of cells naturally arises, because the amount of radiation absorbed during highmagnification imaging is sufficient to cause cell death . These are the phloem fibers. Specialized cells in the xylem tissue called tracheids and vessel elements have evolved specifically for this ability by forming hollow tubes with lignified secondary walls.
