The xylem tube contain a ring of lignin which forms a spiral pattern around the xylem tube.
The xylem is made up of water proof, dead cells; which enables it to have high capacity for transporting large quantity of water
store water
Lignin is a type of polymer found in the cell walls of plant cells that provides support and structure for the plant- it makes them rigid.
Bacteria do not have xylem so they use their cell membranes to carry.
They are organelles;
Nerve cells have many adaptations to their function. The basic function of a nerve cell is to deliver a message to the next nerve cell in order to send information across the body. It has long axon that deliver an action potentially a long way.
R.B.C have hemoglobin molecule which carry carry oxygen
store water
its a specialised cell because its characteristics are adapted to its function. for example, the red blood cell is round and flat so it can carry oxygen efficiently

The water conducting tissue of a plant cell is called xylem. Xylem is responsible for transporting water from the roots to the rest of the plant, providing hydration and nutrients. It is made up of specialized cells that are adapted for efficient water transport.
Bacteria do not have xylem so they use their cell membranes to carry.
Xylem is a type of cell that distributes water throughout a plant. They have specialized cells that help water flow up a plant, to get where it is needed.
Xylem cells carry water and nutrients from the roots to other parts of a plant.
They are organelles;
it is long and thin so can carry impulses quickly and easily from the central nervous system (the spinal chord and brain) to the parts of the body that have recieved a reaction.
Nerve cells have many adaptations to their function. The basic function of a nerve cell is to deliver a message to the next nerve cell in order to send information across the body. It has long axon that deliver an action potentially a long way.
The same as the function of ribosomes in any other cell: to translate mRNA into protein that the cell can use to carry out its functions.
