Protoplasts in tobacco leaf cells
Numéro d’image : 11523566
| Light micrograph of protoplasts from a tobacco leaf,Nicotiana plumbaginifolia,showing cells from the mesophyll layer. A protoplast is a single intact cell,which has been chemically treated to remove the tough outer cellulose wall,leaving only the delicate plasma membrane binding the cell contents into a whole. The cell wall can later be regrown. The mesophyll layer contains numerous chloroplasts (green),the sites of photosynthesis. Protoplasts,being easier to manipulate,are used in plant genetic engineering; experiments in hybridization & disease resistance Protoplast technology is pertinant also to biotechnology & medicine.
