Definitions:

Mineral Uptake

The process by which plants absorb minerals from the soil through their roots.

Phloem

Complex vascular tissue of plants; its living sieve elements compose sieve tubes that distribute sugars through the plant body. Each sieve element has an associated companion cell that provides it with metabolic support.

Sugars

Carbohydrates that taste sweet and are used by the body for energy.

Plant Tissue

Groups of cells within a plant that perform specific functions, such as transport (xylem, phloem), support (collenchyma, sclerenchyma), or photosynthesis (parenchyma).
