Collenchyma cells are most often found adjacent to outer growing tissues such as the vascular cambium and are known for increasing structural support and integrity. The first use of "collenchyma" ( / k ə ˈ l ɛ ŋ k ɪ m ə , k ɒ -/ [ 7 ] [ 8 ] ) was by Link (1837) who used it to describe the sticky substance on Bletia (Orchidaceae) pollen.
Phloem (/ ˈ f l oʊ. əm /, FLOH-əm) is the living tissue in vascular plants that transports the soluble organic compounds made during photosynthesis and known as photosynthates, in particular the sugar sucrose, [1] to the rest of the plant.

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 ...
The secondary cell wall is a structure found in many plant cells, located between the primary cell wall and the plasma membrane.The cell starts producing the secondary cell wall after the primary cell wall is complete and the cell has stopped expanding. [1]
