parenchyma cells
A relatively unspecialized plant cell type that carries on most of the metabolism synthesizes and stores organic products, and develops into more differentiated cell types.
Parenchyma cells have a variety of functions:
In leaves, they form the mesophyll and are responsible for photosynthesis and the exchange of gases[1].
Storage
Secretion (e.g. Epithelial cells lining the inside of resin ducts)
Healing ...
A tissue of mostly parenchyma cells that makes up the bulk of a young plant and fills the space between the dermal and vascular tissue systems.
growth factor ...
palisade parenchyma Parenchyma cells in the leaf mesophyll characterized by uniform rows of tightly packed cells with many chloroplasts beneath the upper epidermis.
pallium Mantle of a mollusc or brachiopod.
A generalized plant cell type, parenchyma cells are alive at maturity. They function in storage, photosynthesis, and as the bulk of ground and vascular tissues.
Layers of parenchyma cells. These store food (as they do in the root). In the very young stem (before cork has formed), they may have chloroplasts and carry on photosynthesis.
Cork cambium.
Parenchyma cells have thin, usually multisided walls, are unspecialized but carry on photosynthesis and cellular respiration and can store food; form the bulk of the plant body; found in the þeshy tissue of fruits and seeds, ...
Often less specialized than other plant cell types, parenchyma cells are surrounded by thin, flexible primary walls and execute most of the plant's metabolic activities.
