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.
Water is also necessary for photosynthesis to occur. You probably already know that when you water a plant the water is absorbed through its roots. The water travels through the roots up long tubes that lead from the roots to other parts of the plant. These tubes are called xylem.
