2. Ground tissue - Wikipedia

   en.wikipedia.org/wiki/Ground_tissue

   Parenchyma forms the "filler" tissue in the soft parts of plants, and is usually present in cortex, pericycle, pith, and medullary rays in primary stem and root. Collenchyma cells have thin primary walls with some areas of secondary thickening. Collenchyma provides extra mechanical and structural support, particularly in regions of new growth.

3. Vascular cambium - Wikipedia

   en.wikipedia.org/wiki/Vascular_cambium

   Helianthus stem in section. The cells of the vascular cambium (F) divide to form phloem on the outside, located beneath the bundle cap (E), and xylem (D) on the inside.

4. Plant stem - Wikipedia

   en.wikipedia.org/wiki/Plant_stem

   Ground tissue usually consists mainly of parenchyma, collenchyma and sclerenchyma cells, and they surround vascular tissue. Ground tissue is important in aiding metabolic activities (eg. respiration, photosynthesis, transport, storage) as well as acting as structural support and forming new meristems. [7]

5. Plant cell - Wikipedia

   en.wikipedia.org/wiki/Plant_cell

   Structure of a plant cell. Plant cells are the cells present in green plants, photosynthetic eukaryotes of the kingdom Plantae.Their distinctive features include primary cell walls containing cellulose, hemicelluloses and pectin, the presence of plastids with the capability to perform photosynthesis and store starch, a large vacuole that regulates turgor pressure, the absence of flagella or ...

6. Pericycle - Wikipedia

   en.wikipedia.org/wiki/Pericycle

   The pericycle is a cylinder of parenchyma or sclerenchyma cells that lies just inside the endodermis and is the outer most part of the stele of plants. [ citation needed ] Although it is composed of non-vascular parenchyma cells, it's still considered part of the vascular cylinder because it arises from the procambium as do the vascular tissues ...

7. Solid surface material - Wikipedia

   en.wikipedia.org/wiki/Solid_surface_material

   Solid surface material, also known as solid surface composite, [1] is a man-made material usually composed of a combination of alumina trihydrate (ATH), acrylic, epoxy or polyester resins and pigments. It is most frequently used for seamless countertop installations. A solid surface material was first introduced by DuPont in 1967 under the name ...

8. Pith - Wikipedia

   en.wikipedia.org/wiki/Pith

   Pith is composed of soft, spongy parenchyma cells, which in some cases can store starch. In eudicotyledons, pith is located in the center of the stem. In monocotyledons, it extends only into roots. [1] The pith is encircled by a ring of xylem; the xylem, in turn, is encircled by a ring of phloem.

9. Parenchyma - Wikipedia

   en.wikipedia.org/wiki/Parenchyma

   The tumor parenchyma, of a solid tumour, is one of the two distinct compartments in a solid tumour. The parenchyma is made up of neoplastic cells. The other compartment is the stroma induced by the neoplastic cells, needed for nutritional support and waste removal. In many types of tumour, clusters of parenchymal cells are separated by a basal ...
