Xylem-the water potential of the cell above it means that water is 'sucked' up the tube like a straw. Waste products are disposed of parallel to the xylem in the phloem, in the opposite direction of course. The xylem is made up of lignified (or 'dead') cells to keep the stem upright and provide support. Hope that helps :)

Can you make salt water stack on a tube?
It is because of Capillary action, the adhesive forces for water are effective in narrow tube, in a wide tube the weight of water resists the upwards movement of water.
Yes it does.
It depends on what size test tube you are using.
Yes, stalactites can sometimes have a hollow central tube depending on how they formed. This can occur when water drips through the center of the stalactite, leaving behind the hollow tube as the mineral deposits accumulate on the outside.
A long hollow tube was first used as a scope.

Yes, insects simply stab through sharp hollow tube. Stabbing sharp hollow tube's just a law of nature

A stalactite is a thin hollow tube that forms when water drips from the cave ceiling through its center, leaving behind mineral deposits that build up over time.
A tube is a hollow cylinder.
A hollow central tube is characteristic of a hydrothermal vent, which is a fissure in the Earth's surface that releases geothermally heated water. These vents are typically found on the ocean floor near tectonic plate boundaries.
a tube is a hollow cylinder , a cylinder can be hollow or solid - according to my Websters dictionary
Water-vascular system.

Interconnected canals and hollow tube feet work together in a sea star's water vascular system, which helps with movement, feeding, and respiration. Sea stars use water pressure to extend and retract their tube feet, enabling them to grip surfaces and capture prey.
