Phloem transport of sucrose can be described as going from “source to sink” which of the following would not normally function as a sink?

سوکروز کی فلوئم ٹرانسپورٹ کو "ذریعہ سے ڈوبنے" کے طور پر بیان کیا جا سکتا ہے مندرجہ ذیل میں سے کون سا عام طور پر سنک کے طور پر کام نہیں کرے گا؟
Answer: Mature leaf
Explanation
  • In the context of phloem transport, "source" refers to the location where sucrose is produced (usually leaves).
  • While "sink" refers to the location where sucrose is consumed or stored (e.g., roots, stems, fruits, and storage organs).
  • A mature leaf is typically a source, not a sink, as it produces sucrose through photosynthesis.
