Xylem vessels are made up of dead cells with a thick, strong cell walls and have a hollow lumen that allows water to flow through them.
The xylem cells form continuous tubes from the leaves down to the roots. This acts like a drinking straw and helps in the flow of water with dissolved minerals from the roots to the leaves.
xylem transports water around the plant whilst the phloem is responsible for transporting nutrients.
^ horible answer ^
the xylem is specialised by it has pits in the sides of it so the water can flow sideways and in the roots the xylem is cross shaped so it is strong.
Phloem is the type of cell that delivers nutrients throughout a plant. Inside phloem cells are specialized cells called sieves that help transport these nutrients.
The cells having sieve like perforations in their cell walls present in phloem are the sieve tubes of the phloem.
In a tree or any type of plant.
meristematic cells phloem xylem
What colour are chloroplasts
It has a huge fat globule.Nucleus is near the border of cell
phloem is a plant cell
Phloem consists for a sieve tube and a companion cell
The cells having sieve like perforations in their cell walls present in phloem are the sieve tubes of the phloem.
turn you on.
yes, in that it has no plasticity.
It is trianglular and has spikes. Also the phloem cell structure is made up of many spirals which enables it to stay strong.
for example phloem .... doesnt have a nucleus ... and it needs a nucleus to survive ... thats why they have a companion cell which have a nucleus for them ...if u try to separate the companion cell from the phloem the phloem will die after some time
companion cell
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

A sperm cell (gamete) is a specialised cell because it only performs one function: to fertilise an egg, and its structure relates to it's function. For example, the sperm cell's long tail helps it swim faster.
