Stolon – A branch that forms near the base of the plant, grows horizontally, and roots and produces new plants at the nodes or apex. Stoloniferous – plants producing stolons. Semi-erect – Not growing perfectly straight. Suffrutescent – somewhat shrubby, or shrubby at the base. Upright – Growing upward.
This is a diagram of cell elongation in a plant. In sum, the acidity within the cell wall as a result of a high proton concentration in the cell wall. As a result,the cell wall becomes more flexible so that when water comes into the plant vacuole, the plant cell will elongate. This image shows the development of a normal plant.
Leaves of most plants include a flat structure called the blade or lamina supported by a network of veins, a petiole and a leaf base; [1] but not all leaves are flat, some are cylindrical. [citation needed] Leaves may be simple, with a single leaf blade, or compound, with several leaflets.
The lycophytes or lycopodiophytes – modern clubmosses, spikemosses and quillworts – make up less than 1% of living vascular plants. They have small leaves, often called 'microphylls' or 'lycophylls', which are borne all along the stems in the clubmosses and spikemosses, and which effectively grow from the base, via an intercalary meristem.

Cotyledon from a Judas-tree (Cercis siliquastrum, a dicot) seedling Comparison of a monocot and dicot sprouting. The visible part of the monocot plant (left) is actually the first true leaf produced from the meristem; the cotyledon itself remains within the seed Schematic of epigeal vs hypogeal germination Peanut seeds split in half, showing the embryos with cotyledons and primordial root Two ...
Variation in leaves from the giant ragweed illustrating positional effects. The lobed leaves come from the base of the plant, while the unlobed leaves come from the top of the plant. Although plants produce numerous copies of the same organ during their lives, not all copies of a particular organ will be identical.
The stems of Athrotaxis are covered with small flat pointed leaves called "scale leaves" or "cataphylls". In plant morphology, a cataphyll (sometimes also called a cataphyllum [1] or cataphyll leaf [2]) is a reduced, small leaf. [3] Many plants have both "true leaves" (euphylls), which perform most of the photosynthesis, and cataphylls, which ...
A plant cell wall was first observed and named (simply as a "wall") by Robert Hooke in 1665. [3] However, "the dead excrusion product of the living protoplast" was forgotten, for almost three centuries, being the subject of scientific interest mainly as a resource for industrial processing or in relation to animal or human health.
