Plants are made up of organs (root, stem, leaf, and flower); organs consist of tissues (meristems ... at higher pHs encountered in the cytoplasm of leaf sieve cells of the phloem (the ionization ...

We have looked at seeds and roots of plants, and now we are going to study the stems. Plant stems are defined as the axis, or the ...

The vascular network consisting of phloem and xylem (wood) provides plants with structural support and long-distance transport that specifies further downstream processes in the sink tissues (such as ...
