There are two types of pathways in roots by which surrounding materials from the environment can get transported into plants. the _______ pathways involves materials being transported in-between cells while the _______ pathways involves materials being transported inside of cells.

Guttation

Which of the following describes the name of the process in which plants secrete water and other molecules through their stoma, with the asssitance of guard cells?

Plastic refers to the plants plasticity within its environment. This means a plant is capable and often very good at adjusting to and conforming to its given environment.

In pre-lab handout and control, it was stated that plants are both highly organized and that this organization is plastic. please describe what plastic refers to.
