Nutrients necessary for the structure and function of multicellular organisms.

Process by which organisms acquire nutrients through roots.

Process where plants convert CO2 into carbohydrates using light.

Molecules involved in normal growth and reproduction of plants.

Compounds that aid in survival, not directly related to growth.

Process of nutrient absorption involving the exchange of cations in soil.

Fungi that form symbiotic relationships with plant roots, enhancing nutrient uptake.

Various ways plants obtain nutrients, including carnivory and parasitism.

Magnesium is a co-factor for chlorophyll; deficiency causes yellowing leaves.

Indicates which parts of a plant show deficiency symptoms first, related to nutrient movement.

Soil is an unconsolidated, biologically active medium with both biotic and abiotic components.

Different layers of soil: O (Organic), A (Topsoil), B (Subsoil), C (Underlying material).

Soil provides mechanical support, mineral nutrients, water, and oxygen to plants.

Growth involves seeking resources through roots and new stem/leaf development.

Substances needed by plants in large quantities to produce primary and secondary metabolites.

Substances required by plants only in small quantities, often necessary for making secondary metabolites and coenzymes.

Signs indicating a lack of nutrients in plants, revealing how nutrients are utilized.

Non-protein molecules that assist enzymes in their function, often derived from micronutrients.

Minerals or other compounds that assist with enzyme activity, essential for proper biochemical reactions.

Naturally occurring inorganic substances needed by plants, categorized within macronutrients and micronutrients.

The study of how plants obtain and utilize nutrients for growth and development.
