Pressure-flow Model

A hypothesis that explains how phloem sap (sucrose and other substances) moves through a plant from a source (where it's produced or stored) to a sink (where it's used or stored).

Cellular Respiration

A metabolic process that converts nutrients into energy (ATP) and waste products in the presence of oxygen, within the cells.

Phloem Transport

The movement of nutrients, particularly sugar (sucrose), and other solutes throughout a plant via the phloem tissue.

Parenchyma Cells

Fundamental plant cells that are alive at maturity, usually found in leaves' mesophyll and involved in functions like photosynthesis, storage, and tissue repair.
