The Two Phases of Sporophyte Development, most of them live on the ground and in the air, a medium often unfavourable to life. So it is not surprising to see that all these plants use more or less sophisticated means to avoid problems of the medium to the first stages of their sporophyte development. This development can be divided into t

Cytology of the Processes of Differentiation and Dedifferentiation During the Ontogeny of Vascular Pnts concerns, on the one hand, the diversification of cells derived from meristematic proliferation, i. e. the cells concerned with the formation of all the various tissues of the plant and, on the other hand, with the production of more or less specialized cells that regain the condition of meriste

Secretory Cells and Secretory Tissuesls are specialized cells derived from elements belonging to other tissues, mainly epidermis or parenchymatous tissues. In such cases, they do not constitute true independent tissues and it is justified to speak of secretory parenchymas or secretory epidermis.
