Plant Nutrients and Photosynthesis

Flashcards about plant nutrients, photosynthesis, and nitrogen metabolism.

Non-Mineral Nutrients

Carbon, Hydrogen, and Oxygen; generally available to plants through air and water.

Primary Macronutrients

Nitrogen, Phosphorus, and Potassium; available through soil but usually not through fertilizers.

Secondary Macronutrients

Calcium, Magnesium, and Sulfur; available through soil, but usually not through fertilizers.

Micronutrients

Includes Nickel, Iron, Manganese, Zinc, Copper, Boron, Molybdenum, and Chlorine; available through soil, but usually not through fertilizers.

Chlorophyll

Nitrogen is an essential part of this compound

Iron deficiency

Yellow leaves or leaves with green veins

Calcium deficiency

Stunted and misshapen new leaves

Nitrogen deficiency

Light green upper leaves, yellow leaves, yellow and shriveled

Potassium deficiency

Yellowish at edges and tips with dead spots and yellow patches

Phosphate deficiency impacts on livestock production

Plant and soil deficiencies can lead to reduced weight, body condition score, milk production, pregnancy rates, increased mortality, lameness and brittle bones, and pica in livestock

Crop yield

The amount of nutrients directly relates to this.

Nitrogen Metabolism

A key biochemical process in plant development; involves the uptake of inorganic and organic nitrogen by plants.

NRTs

Nitrate transporters that function in nitrate absorption and transportation in plants.

Plant Adaptation to Different Environments

Low nutrient conditions can lead to differences in genetics, gene transcription levels (transcriptome), and protein activity (proteome), resulting in differences in phenotype.
