10 Questions
What are the total essential plant nutrients?
The total essential plant nutrients include seventeen different elements: carbon, oxygen, hydrogen, nitrogen, phosphorus, potassium, calcium, sulfur, magnesium, iron, boron, chlorine, manganese, zinc, copper, molybdenum, and nickel.
From where do plants absorb carbon, oxygen, and hydrogen?
Plants absorb carbon, oxygen, and hydrogen from the air.
What is the law that the study of plant nutrition is in accordance with?
The study of plant nutrition is in accordance with Justus von Liebig’s law of the minimum.
In what quantities are micronutrients present in plant tissue?
Micronutrients are present in plant tissue in quantities measured in parts per million, ranging from 0.
How do plants absorb essential elements from the soil?
Plants absorb essential elements from the soil as ions, as these elements stay beneath the soil as salts.
What did Justus von Liebig prove in 1840?
Plants needed nitrogen, potassium, and phosphorus.
What is the Casparian strip and how does it help in nutrient uptake?
A cell wall outside the stele that prevents passive flow of water and nutrients, helping to regulate the uptake of nutrients and water.
How do plants take up essential elements from the soil?
Through their roots and cation exchange, wherein root hairs pump hydrogen ions into the soil through proton pumps.
What is Liebig's law of the minimum and how does it relate to plant growth?
Liebig's law of the minimum states that a plant's growth is limited by nutrient deficiency.
What role does water potential play in a plant's nutrient uptake?
Water potential plays a key role in a plant's nutrient uptake, as nutrients move from the region of higher solute concentration in the soil to the area of lower solute concentration in the plant.
