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.
Why is the waxy cuticle on a leaf? The waxy cuticle prevents the excessive transpiration from the leaves. However, the transpiration, a term for water evaporation from plants, can still occur through stomata. Wâ¦ithout cuticle layer, the water will evaporates through the epidermis much more easily.   The transpiration itself is an important factor that drives the water movement inside a plant. As a water in a leaf evaporates, the empty space left in the leaf will pull the water molecules from roots and stem.
