No xylem die at maturity but phloem stays alive all the time the plant is alive.
The absorption of a photon by special protein in the inner membranes of the chloroplast (p680) causes the hydrolysis of water into Hydrogen and Oxygen. 2 H2O + 2 NADP+ + 2 ADP + 2 Pi + light → 2 NADPH + 2 H+ + 2 ATP + O2 The resultant energy is harnessed by coupling the movement of protons down a concentration gradient to the phosphorylation of ADP. see http://www.answers.com/topic/photosynthesis
The cells in the middle of a carrot (vascular bundle) consist of xylem & phloem. Xylem are responsible for water transportation and phloem transports nutrients. These tissues are primarily made of sclerenchyma cells as well as parenchyma cells.
The elongated shape of phloem cells allows for efficient transport of sugars and other nutrients throughout the plant. This shape provides a larger surface area for nutrient exchange and enables the phloem to form continuous tubes for long-distance transport. Additionally, the presence of sieve plates in phloem cells allows for the movement of materials between cells.
Because to stay alive
To make energy for their bodys, and to STAY ALIVE!!!
No, mature phloem tissue is not dead upon maturity. Phloem tissue remains alive and functional, aiding in the transport of sugars and other organic compounds throughout the plant. The cells in mature phloem tissue are specialized for this function and typically stay alive for an extended period.
Plants have specialized tissues called xylem and phloem that provide structural support. Xylem transports water and minerals from the roots to the rest of the plant, while phloem transports sugars produced during photosynthesis. These tissues help maintain turgor pressure and provide rigidity to the plant structure, allowing it to stay upright. Additionally, some plants have evolved mechanisms such as lignin deposition and secondary growth to strengthen their stems and support their growth.
The xylem translocates water from the radicle to the leaves for photosynthesis. The Phloem translocates the products of photosynthesis to the growing areas of the plant i.e. the Radicle (Root) and Plumule (Shoot)

A leaf, by definition, is vascular with xylem and phloem moving nutrients and byproducts to and from the leaves. The mango leaf has a leathery texture and looking at it from the top, the venation is pinnate, brachidodrome.

i think a nonvascular does have stomata becuz they have to be able to breath and stay alive in order to develop spores.they have to go through a life cycleand gthey drop spores and the sproes have to grow in the ground or sprout.then they grow a plant that comes out of a spore.spores can be transpoted to any where they go .they can get carried by wind,birds or water as long they are in the ground .
Stay in alive is a disco.
The duration of To Stay Alive is 1.58 hours.
Organs and tissues are needed for a great many things. These organs and tissues help make the body function properly.
kittens stay alive for 15 years
