In plants, water is transported through vessels called xylem. The cohesiveness of water molecules allows them to travel up the walls of the vessel. However, for most plants this is not enough to move the water all the way to the top of the plant. How do plants overcome the force of gravity and move water to their upper tissues? Root hairs push water through the roots and up into the xylem Plants absorb water through transpiration to supply their upper tissues with water. The guard cells surrounding the stomata expand and contract, pushing water through the xylem. Water escapes from the leaves through transpiration, creating a vacuum which pulls water up the xylem

Zoe decided to measure the hand length of each of her classmates. first she marked a line across each student's wrist and lined up a ruler from this mark to the top of the middle finger to measure the length. then she recorded the measurements in the table below. marla did this the same way for each classmate, and then zoe used this ruler to measure each straight line and record the data below. this data is invalid. what is the most likely reason why it is invalid? the ruler is marked in centimeters, but zoe recorded data in inches. the range of lengths is too wide, so zoe must have misread the ruler. marla’s complicated measuring procedure was overly confusing. marla could have been inconsistent while drawing outlines of fingers.
