What makes new xylem and phloem?
The new xylem is produced by the division and differentiation of cells in the vascular cambium layer, while new phloem is produced by the division and differentiation of cells in the vascular cambium or the procambium during secondary growth in plants. These cells differentiate into xylem vessels, fibers, and phloem sieve tubes, companion cells, and fibers respectively.
What is vascular tissue composed of?
Vascular tissue is composed of two main types of cells: xylem and phloem. Xylem cells transport water and minerals from the roots to the rest of the plant, while phloem cells transport sugars produced through photosynthesis to various parts of the plant. These two types of cells work together to form the complex network that allows plants to circulate essential substances throughout their systems.
Does vascular plants have specialized transporting cells?
Yes, vascular plants have specialized transporting cells known as xylem and phloem. Xylem transports water and dissolved minerals from the roots to the rest of the plant, while phloem distributes sugars and nutrients produced through photosynthesis. These specialized cells enable vascular plants to efficiently transport essential substances, supporting their growth and overall function.
Where are xylem cells that no longer conduct water found?
Non-conducting xylem cells are found in the heartwood of trees. As a tree ages, the inner layers of xylem cells lose their ability to conduct water and become filled with resins, gums, and other substances that help provide structural support to the tree.
What is spongy mesophyll layer?
Spongy mesophyll cells are not packed so tightly together, which allows carbon dioxide and oxygen to reach the palisade cells where they are needed in photosynthesis. Spongy mesophyll cells and guard cells (see below) also get some photosynthetic action.
Is mesophyll is cell?
In the middle of the leaf, in line with the xylem cells (under the palisade cells but above the stomata)
What are types of mesophyll cells?
The two main types of mesophyll cells found in plant leaves are palisade mesophyll cells and spongy mesophyll cells. Palisade mesophyll cells are located in the upper layer of the leaf and are specialized for photosynthesis, while spongy mesophyll cells are found beneath the palisade layer and aid in gas exchange and the storage of nutrients.
When largest stem xylem's cells of an oak are produced?
spring

Is the xylem a plant tissue?
yes the xylem is one of the plant tissues the others are phloem and the palisade layer. the plant organs are the stem, leaf and roots.
Which components of a geranium plant have functions similar to those of the arteries and veins of humans?
a) xylem and phloem b) cambrium and epidermis c) chloroplasts and guard cells d) palisade and spongy layers ?
Wot features do leaf cells have?
Waxy cuticle, Palisade cells, spongy mesophyll, vascular bundle (xylem, phloem). Plant cell : Nucleus, vacuole, cytoplasm, centriole, lysosomes, cell membrane, cell wall. etc etc.
What is Flowem zylem?
Xylem and phloem are two types of plant tissues responsible for transporting water, nutrients, and other substances throughout the plant. Xylem carries water and minerals from the roots to the leaves, while phloem transports sugars produced in the leaves to other parts of the plant. Together, they form the vascular system of plants.
What layer in a leaf does carbon dioxide moves freely and xylem and phloem are found?
Cuticle
