Step 1
C. cabbage plants grown in a phosphorus-deficient soil mobilise phosphorus from tissues and release it into the phloem.
Answer
This statement describes a vital process for sustaining cellular functions and maintaining homeostasis in plants. When cabbage plants face phosphorus deficiency, they actively mobilise phosphorus from their tissues. This adaptive response enables the plants to maintain nutrient balance crucial for energy transfer and metabolism. The released phosphorus is then transported through the phloem, ensuring that essential nutrients are adequately distributed, even in suboptimal conditions. This mechanism highlights the plant's ability to respond to environmental stressors effectively.
