Yes xylem cells are hollow because Xylem are just made up from cell walls left from cells, making hollow tubes. The walls of these tubes are hydrophilic, so water attaches readily to them, helping it to climb on its way up the plant
Xylem is a type of vascular tissues present in flowering plants. It is responsible for the transport of materials in the plants. The xylem tissue has two main functions. It is used to conduct water, along with its dissolved mineral salts, from the roots to the stems and leaves of the plant. Xylem also provides mechanical support in the plant.
They are hollow to transport water and strong to supprt the stem
It is strengthened by spirals or circles of a substance called lignin.
Yes, xylem tubes are hollow as it is this structure which allow the transport of carbohydrates.
They are hollow to transport water and strong to support the stem
No, xylem cells are "dead" cells and therefore do not undergo cell division.
xylem cells are *~!BLUE!~* because of the presence of lignin
- Walls made from dead lignin cells, which waterproof and support walls even if water levels are low in plants. - Narrow tubes so water column doesn't break easily. - Pits in walls allow water to move from one cell to another.
A layer of cambium cells separates the xylem and phloem tubes.

Xylem cells are in plants not animals.
Xylem cells are found in vascular plants.
xylem cells are present in the plant coducting tissue called xylem. they aren't in human body anywhere.

One is to transport the water and the minerals. The cells are adapted to this job because they do not contain cytoplasm so the water and minerals can travel through the xylem more easily. Two is to support the plant. Their walls have lignin (hard material)
Vessels are types of advanced xylem cells that are found in angiosperms. An xylem is made up tracheids and both of these cells have pits so that water can move sideways in the stem.
