Commercial uses – Falcataria falcata softwood is used to make match-sticks, chopsticks, shipping pallets, and wooden boxes. The pulp is used for paper-making. [10] Plywood production and veneer based products have increasingly been an important use for these trees. [6] Traditional uses – Whole tree trunks are carved for seagoing canoes.
Falcataria is a genus of flowering plants in the family Fabaceae. It belongs to the monophyletic Mimosoid clade [ 1 ] [ 3 ] in the subfamily Caesalpinioideae . [ 3 ] The genus has three species previously classified in the Falcataria section of the genus Paraserianthes by I.C. Neilsen.
The falcata has a single-edged blade that pitches forward towards the point, the edge being concave near the hilt, but convex near the point. This shape distributes the weight in such a way that the falcata is capable of delivering a blow with the momentum of an axe, while maintaining the longer cutting edge of a sword, as well as the facility to thrust.
Neutralism (a term introduced by Eugene Odum) [22] describes the relationship between two species that interact but do not affect each other. Examples of true neutralism are virtually impossible to prove; the term is in practice used to describe situations where interactions are negligible or insignificant. [23] [24]
Guard cell – one of the paired epidermal cells that control the opening and closing of a stoma in plant tissue. Heartwood – the older, nonliving central wood of a tree or woody plant, usually darker and harder than the younger sapwood. Also called duramen. Herbaceous – non-woody and dying to the ground at the end of the growing season.
The cell is the fundamental unit of structure and function in all living organisms. [14] The activity of an organism depends on the total activity of independent cells. [15] Energy flow (metabolism and biochemistry) occurs within cells. Cells contain DNA which is found specifically in the chromosome and RNA found in the cell nucleus and ...
Cell division for both the diatom host and cyanobacterial symbiont can be uncoupled and mechanisms for passing bacterial symbionts to daughter cells during cell division are still relatively unknown. [63] Other endosymbiosis with nitrogen fixers in open oceans include Calothrix in Chaetoceros spp. and UNCY-A in prymnesiophyte microalga. [64]
Modelling biological systems is a significant task of systems biology and mathematical biology. [a] Computational systems biology [b] [1] aims to develop and use efficient algorithms, data structures, visualization and communication tools with the goal of computer modelling of biological systems.
