OBSERVATION ON EPIDENMIS CELLS OF SERVERAL EMERGING PLANT''S LEAVES

Abstract:

It is well known that the roots of emerging plant grow in soil immersed inwater, but their stems and leaves spread out in air. The epidermis cells of the leaves of 4emerging plants have been observed by the microscope. It is discovered that water can notaffect so obviously the epidermis cells of them as that of floating and submerged plants.Constitution of epidermis cells of these emerging plants is different from that of submergedand floating plants, but similar to that of terrestrial plants. That is to say, stomata andstomatal apparatus exist in epidermis of emerging and terrestrial plants and there areepidermal hair on some epidermis.
