Chloroplasts are the site of photosynthesis and are green because of the presence of chlorophyll pigments. Saved by Leafcutter Designs. The viewed specimen clearly shows the location of vascular bundles and the xylem, phloem and sclerenchyma or collenchyma. Here is an example of what you would see with a magnifying glass or with a microscope. This new resource supports the use of practicals across various A-level biology specifications. It is wavy in outline and thus shows distinct ridges and furrows (Fig. Carefully add a drop of tap water and lower the cover slip onto the celery.
