SO ENDS this first weekend on the differences between plants and animals. Plants are completely different from animals, in structure, development, reproduction, and evolution. It could be argued that it is surprising that these two kingdoms mesh together so well, having so few similarities. But plants essentially form the first complex molecules from sunlight that fuel most of the other creatures on earth. View in LinkedIn

ORGAN GROWTH IN PLANTS. “In contrast to animals, organogenesis in plants is a postembryonic and continuous process. Differentiated plant cells can revert to a pluripotent state, proliferate and transdifferentiate. This unique potential is strikingly illustrated by the ability of certain cells to produce a mass of undifferentiated cells or a fully totipotent embryo, which can regenerate mature plants.” https://lnkd.in/g8-4Y_M View in LinkedIn

THE SET-ASIDE. “The reproductive organs of the flower are differentiated from a reprogrammed shoot meristem after the seedling has become a mature plant. Thus, a germline analogous to that found in animals is not set aside during plant embryogenesis.” https://lnkd.in/g_k-4-g View in LinkedIn

CELL CYCLE. “Plant genome projects have revealed that both the cell-cycle components and the overall cell-cycle architecture are highly evolutionarily conserved. In addition to the temporal and spatial regulation of cell-cycle progression in individual cells, multicellularity has imposed extra layers of complexity that impinge on the balance of cell proliferation and growth, differentiation and organogenesis.” https://lnkd.in/g8-4Y_M View in LinkedIn

TRANSITION. “Meiosis marks the transition to the gametophytic phase, and fusion of the gametes during fertilization starts the embryonic phase of the next generation.” https://lnkd.in/gkwnBWu View in LinkedIn

DEVELOPMENT OPTIONS. “Upon transition to the postembryonic state the organism either immediately possesses the principal pubertal morphological characteristics (direct development) or essentially differs from the pubertal form, in which case the larva that hatches out of the egg must undergo a metamorphosis before it reaches its adult state.” http://encyclopedia2.thefreedictionary.com/Postembryonic+Development View in LinkedIn

CONTINUOUS ORGANS. “Vegetative organ systems differentiate continuously from root and shoot meristematic regions that are formed initially during embryogenesis.” http://www.jstor.org/stable/pdf/2885440.pdf?seq=1#page_scan_tab_contents View in LinkedIn

INDEPENDENT EXISTENCE. “Postembryonic development begins after the emergence of the embryo from the egg and embryonic membranes, when the organism becomes capable of active feeding and locomotion.” http://encyclopedia2.thefreedictionary.com/Postembryonic+Development View in LinkedIn

MORPHOGENESIS. “Most morphogenic events in flowering plants occur in the postembryonic sporophyte after seed germination.” http://www.jstor.org/stable/pdf/2885440.pdf?seq=1#page_scan_tab_contents View in LinkedIn

DIPLOID SPOROPHYTE. “By contrast, the diploid, or sporophytic, generation begins after fertilization with the zygote and forms the mature plant with vegetative organs (leaf, stem, root) and flowers that contain the reproductive organs (anther and pistil).” http://www.jstor.org/stable/pdf/2885440.pdf?seq=1#page_scan_tab_contents View in LinkedIn
