The main light-collecting structure on a leaf is a large, broad, flat surface called the leaf blade. The blade is held away from the stem and supported by the petiole. Monocots have leaves with parallel veins. Dicots have leaves with veins that connect and branch from each other.
1 sty 1999 · In general, the primary and secondary veins are the major structural veins of the leaf, while the tertiary veins are the largest veins that fill the field of the leaf. The primary...
18 kwi 2013 · We synthesize classical concepts and the recent literature on a wide range of aspects of leaf venation. We describe 10 major structural features that contribute to multiple key functions, and scale up to leaf and plant performance.
1 sie 2021 · The findings provide a deep understanding of the optimization mechanism of leaf veins, which is useful for the design of high-performance shell structures. Three leaf species used in...
LEAF VEINS The internal connections of the leaf to the rest of the plant are through veins. Leaf veins are actually vascular bundles. Vascular bundles (recall from Chapter 4) are composed of xylem (to transport water) and phloem (to transport sugars). The pattern they make in leaves is often quite elaborate (Fig. 6.4).
18 kwi 2013 · Inspired by the capillary transport function of plant leaf veins, this study proposes three typical leaf vein features by observing a large number of leaves, including wedge shape, branch...
25 paź 2018 · In the present chapter, we discussed relationships between leaf anatomy and various functions, including light absorption, CO 2 diffusion, water transport, transpiration, and mechanical strength. We also reviewed how leaf anatomy varies depending on species and environments.
