Webbcells support the phloem cells and aid in the movement of substances in and out of the phloem. Ground tissue produces and stores sugars, and helps support the plant. • Parenchyma cells have a thin cell wall and a large central vacuole. • Collenchyma cells have strong, flexible cell walls that help support plant organs. WebbThe phloem of monocots and dicots contains conducting cells (sieve elements) and companion cells. Conducting cells have thin walls, and they are alive in the mature plant, …
Webbspecialized cells of the phloem form a continuous network running throughout the plant. The most widely accepted mechanism for phloem transport is the osmotic pressure-driven mass flow as proposed by Münch in the 1920s (Münch 1930).According to Münch, sugar produced in the leaves generates an osmotic pressure which drives a flow of WebbDescribe the structure of specialised plant cells and relate this to their function.

WebbPhloem tissues consist of two main types of living cells, which you can see in the diagram above: sieve tube members (or sieve tube elements) and companion cells. Companion cells are linked to the sieve tube members by pores in their cell walls called the plasmodesmata, which link together the two cells’ cytoplasm and allow the movement of … how are airpods madeWebbThe cell cannot function without certain organelles and must rely on the organelles of the companion cells. The companion cell is responsible for all metabolic functions of the sieve tube member. The companion cell is essential for the survival of the sieve tube member.
