Therefore, cotinine could stay in your urine for as little as  2 days or as much as 3 months. Answered.
In vascular plants, phloem is the living tissue that carries organic nutrients (known as photosynthate), in particular, sucrose, a sugar, to all parts of the plant where needed.In trees, the phloem is the innermost layer of the bark, hence the name, derived from the Greek word ÏÎ»Î¿Î¹ÏÏ (phloios) meaning bark.n vascular plants, phloem is the living tissue that carries organic nutrients (known as photosynthate), in particular, sucrose, a sugar, to all parts of the plant where needed.

In sugar sinks, cells actively transport solutes out of the sieve-tube elements, producing the exactly opposite effect. Some plants, however, appear not to load phloem by active transport.
