Mobile And Imobile Nutrients Flashcards
(18 cards)
What are the mobile nutrients?
N, P, K, Mg
Mobile nutrients can be moved within the plant through the phloem, leading to deficiencies in older leaves.
What are the immobile nutrients?
Ca, Fe, Zn
Immobile nutrients remain in place within the plant, resulting in deficiencies in young leaves.
Where do deficiencies of mobile nutrients typically appear?
In older leaves
This is because mobile nutrients can be relocated from older to younger leaves.
Where do deficiencies of immobile nutrients typically appear?
In young leaves
Immobile nutrients cannot move within the plant, so deficiencies manifest in the new growth.
What is the purpose of Nitrogen (N) in plants?
Vital for leaf and stem growth, part of amino acids, proteins, and chlorophyll. Promotes lush green foliage.
Nitrogen is essential for the overall health and growth of plants.
What role does Phosphorus (P) play in plant development?
Important for root development, flowering, fruiting, and energy transfer (ATP).
Phosphorus is crucial during the early stages of plant growth and for reproductive processes.
What is the function of Potassium (K) in plants?
Regulates water balance, enzyme activity, improves disease resistance and overall hardiness.
Potassium helps plants respond to environmental stress and enhances their resilience.
What structural role does Calcium (Ca) play in plants?
Structural role in cell walls, helps in root and leaf development, and cell division.
Calcium is important for maintaining the integrity of plant cells.
What is the significance of Magnesium (Mg) in plants?
Central atom in chlorophyll, essential for photosynthesis and enzyme activation.
Magnesium deficiency can lead to reduced photosynthetic efficiency.
What is the purpose of Sulphur (S) in plants?
Part of some amino acids and vitamins, needed for protein synthesis and root growth.
Sulphur is vital for the synthesis of certain essential compounds in plants.
What is the deficiency symptom of Nitrogen (N)?
Older leaves turn pale yellow (chlorosis), stunted growth, poor leaf development
Nitrogen is essential for chlorophyll production and overall plant growth.
How do leaves appear when there is a deficiency of Phosphorus (P)?
Leaves may appear dark green or purplish, especially older leaves
Phosphorus is crucial for energy transfer and photosynthesis.
What are the symptoms of a Potassium (K) deficiency?
Scorched leaf edges (marginal necrosis), curling leaves, weak stems, poor fruit/flower quality
Potassium regulates various physiological processes in plants.
What is a common symptom of Calcium (Ca) deficiency?
Deformed or necrotic young leaves, blossom end rot in tomatoes, poor root development
Calcium is vital for cell wall stability and growth.
What deficiency symptom is associated with Magnesium (Mg)?
Interveinal chlorosis (yellowing between veins) on older leaves, leaf drop
Magnesium is important for chlorophyll synthesis and enzyme function.
What are the symptoms of Sulphur (S) deficiency?
Uniform yellowing of young leaves, similar to nitrogen but starts in new growth
Sulphur is a key component of amino acids and proteins.
What are the macro nutrients?
nitrogen, phosphorus, potassium, calcium, magnesium, and sulphur
What are the micro nutrients
iron (Fe), manganese (Mn), zinc (Zn), copper (Cu), boron (B), molybdenum (Mo), chlorine (Cl), and nickel (Ni)
