Potassium Cycle Flashcards
_______ is a chemical element that has the symbol K and atomic number 19. It is a silvery white metal that is soft enough to easily cut with a knife.
Potassium
It is from the Latin word
‘kalium’ meaning_____ ?
potassium
It was first isolated from _____, the ashes of plants, from which its name was derived from.
potash
What are key roles of POTASSIUM IN PLANTS ?
Osmotic Regulation
Enzyme Activation
Nutrient uptake
Stress Tolerance
Disease Resistance
Potassium helps regulate the opening and closing of
stomata, tiny pores on plant leaves, which control water loss and gas exchange.
Osmotic Regulation
Potassium is involved in activating numerous enzymes responsible for various metabolic reactions within plants.
Enzyme Activation:
_____ is an essential plant nutrient, one of the three macro-elements required by plants in relatively large quantities-nitrogen, potassium, and phosphorus (NPK).
Potassium
Potassium enhances crop yields and quality in different ways. For example, it increases sugar content in fruits, size of vegetable crop fruits, protein content in cereals, helps maintain longer shelf life, improves plants’ resistance to diseases and drought, and more.
True
This macro-nutrient it increases sugar content in fruits, size of vegetable crop fruits, protein content in cereals, helps maintain longer shelf life, improves plants’ resistance to diseases and drought, and more.
Potassium
It helps transport nutrients from the soil into plant roots
and facilitates their movement within the plant to different tissues where they are needed.
Nutrient uptake
Potassium aids in enhancing plant tolerance to various environmental stresses, such as drought, salinity, and extreme temperatures.
Stress Tolerance
Adequate potassium levels in plants can improve their resistance to certain diseases and pests. Potassium strengthens cell walls, making plants more resistant to pathogen attacks and reducing the likelihood of disease development.
Disease Resistance
What are the sources of potassium? Where can u find them ?
•Rocks and Minerals, particularly in minerals like feldspar and mica.
•Soil and Clay Particles
•Decomposing Plants and Animals
•Fertilizers
Potassium is present in rocks and minerals, particularly in minerals like feldspar and mica. Over time, ______ break down these rocks, releasing potassium into the soil.
weathering processes
This interaction ensures that plants can access the potassium they need for essential
physiological functions.
Potassium binds to soil and clay particles
When plants and animals die, their organic matter decomposes. During decomposition, potassium is released back into the soil, enriching it with this essential nutrient for future plant growth.
True
_____is a crucial biogeochemical process that plays a significant role in the movement and recycling of potassium within ecosystems.
potassium cycle
an essential nutrient for plant growth and various physiological functions in living organisms, cyclical path through the environment.
Potassium
What are the potassium cycle process?
Weathering rocks
Plant Uptake
Animal Consumption
Decomposition
Leaching & Runoff
Recyclin
Rocks containing potassium minerals break down over time, releasing potassium into the soil.
Weathering rocks
Plants absorb potassium from the soil through their roots,utilizing it for functions such as enzyme activation, osmoregulation, and overall growth.
Plant Uptake
Animals obtain potassium by consuming plants or plant-eating animals. Potassium is essential for muscle function, nerve transmission, and overall health in animals.
Animal Consumption
When plants and animals die, their organic matter decomposes, releasing potassium back into the soil and completing a vital step in the cycle.
Decomposition
Some potassium dissolves in water and can be carried away by leaching and runoff, moving into rivers, lakes, and oceans, influencing aquatic ecosystems.
