How are the xylem and phloem arranged in plant roots?
capillary action
In the centre of the root
Less transpiration and more absorption
The stomata open wider to let more carbon dioxide into the leaf for photosynthesis
Increase
Water exhibits cohesive behaviour
The oxygen end is slightly negative and the hydrogen end is slightly positive
The humidity increases
The rate of transpiration will _________ if the atmospheric pressure is low.
