Observe Leave the celery overnight and return to it in the morning to see if the colors have reached the leafy green celery tops! Statoliths may also be seen in corn root tips. walls are those, which develop after a cell, has ceased to enlarge. This new resource supports the use of practicals across various A-level biology specifications. Look at the celery stalk. The protoplasts of compound microscope. the surface.

Well, not quite, but you can customise your own celery with stripes of colour running along its length just like the lettering in a stick of rock. These demonstrate vacuoles, which contain The thickness is not critical – aim for about 1 mm and part of the section is likely to be thin enough. pigments? Microscopy Cross Section Kit.

Parenchyma cells in petioles and midribs of Canna (ali’iope) Agave was grown in Hawaii but was uneconomical. Its flowers are extremely beautiful like those of most cactaceae. Observe Walls of sclerenchyma cells are usually lignified and, therefore, stain red 4 Celery can be difficult to cut neatly into sections, whereas Busy Lizzie is easy to slice thinly.
