What is the conclusion after investigating whether roots exert a pushing force strong enough to cause water to move up the stems of plants

From the root pressure experiment, it may be conclude that water molecules move through xylem due to root pressure and not transpiration. The process of osmosis and diffusion helps water to pass from soil to root hair tips and finally to the xylem. Root pressure then joins the water lines inside the xylem and prevent the formation of air bubbles. This also helps in moving the water up. Root pressure is tranverse osmotic in nature and causes guttation at night.

Neurotransmitters are messengers responsible for communication between neurons. they are released from synaptic vesicles and are received by receptors.  the communication is referred to as neurotransmission. the following statement is true about neurotransmitters: a. they're stored in synaptic vesicles in the axon.
