Leaf area index (LAI) is a dimensionless quantity that characterizes plant canopies. It is defined as the one-sided green leaf area per unit ground surface area (LAI = leaf area / ground area, m 2 / m 2) in broadleaf canopies. [1] In conifers, three definitions for LAI have been used: Half of the total needle surface area per unit ground ...
A green leaf is green because of the presence of a pigment known as chlorophyll, which is inside an organelle called a chloroplast. When abundant in the leaf's cells, as during the growing season, the chlorophyll's green color dominates and masks out the colors of any other pigments that may be present in the leaf.

Linking: connects elements selected in one plot with elements in another plot. The simplest kind of ...

A drop-leaf table is a table that has a fixed section in the center and a hinged section (leaf) on either side that can be folded down (dropped). If the leaf is supported by a bracket when folded up, the table is simply a drop-leaf table; if the leaf is supported by legs that swing out from the center, it is known as a gateleg table. Depending ...
Raffia fiber is produced from the epidermal membrane on the underside of the leaf fronds. The membrane is taken off to create a long thin fiber, which can be rolled together for added strength before they are finally dried. Fibres can be made into twine, rope, garden ties, and used in tree grafting.
