According to the dichotomous key what is the name of the plant shown above ?

According to the dichotomous key, the name of the plant shown above is Albizia julibrissin.

A dichotomous key is a tool designed by scientists to allow its user to determine the identity of organisms or objects. The key contains several choices/questions mainly on the observable characteristics of the unknown organism. The questions are usually in steps and in two parts. The questions must be correctly answered because it guides the user to the correct name (scientific) of the unknown organism.  

According to the dichotomous key given above, from the first step, the plant shown has broad leaves (1b) which directs one to step 2. In the second step, the plant has many leaflets (2b) which directs one to step 4. It can be observed that the leaves edges are smooth. This last step which also states the right feature of the plant shows that the name of the plant is Albizia julibrissin.

the bullets go in this order.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
