1 Blood test. 2  This type of pregnancy test can only be done at a doctorâs office. 3  It takes longer than a urine test to get results, but it can detect a pregnancy earlier than a urine test (about 10 days after conception, compared to typically 2 weeks or more for a urine test).
As water molecules evaporate from plant leaves, they attract the water molecules still in the plant, helping to pull water up through the stems from the roots. The combination of transpiration and capillary action delivers the water from the bottom to the top of a plant.
Xylem, which transports water and dissolved minerals, runs from the roots up through the stems and up to the stomates. Refer to your text to familiarize yourself with diagrams of xylem and phloem in typical plant roots and stems. The process of water movement through xylem and out the stomates is known as transpiration.
