Definitions:

Essential Elements

Nutrients required for organisms to survive and reproduce, that cannot be synthesized internally and must be obtained from the environment.

Leaf

A flattened structure of a higher plant, typically green and blade-like, that is attached to a stem directly or via a stalk. Leaves are the main organs of photosynthesis and transpiration.

Guttation

The exudation of droplets of water from the pores of plants, typically occurring at night when root pressure is high and transpiration is low.

Soil Moisture

The amount of water present in the soil which is crucial for the growth of plants and the sustainability of terrestrial ecosystems.
