Spongy tissue is a type of tissue found both in plants and animals. Palisade cells occur in dicotyledonous plants, and also in the net-veined monocots, the Araceae and Dioscoreaceae. Only the midvein and some large lateral veins have any… The elongated palisade parenchyma contains the largest number of chloroplasts per cell and is the primary site of photosynthesis in many plants. They are vertically elongated, a different shape from the spongy mesophyll cells beneath them. Cells in the spongy layer usually contain few chloroplasts (especially in dicot plants) and are the storage place for … ; In xerophytic plants these cells stores water and food in the soluble forms. Other articles where Spongy parenchyma is discussed: angiosperm: Leaves: …to the leaf surface, and spongy parenchyma, located in the lower part of the leaf and composed of irregularly shaped cells. The spongy parenchyma has many spaces between cells to facilitate the circulation of air and the exchange of gases. So, this is the key difference between palisade parenchyma and spongy parenchyma. The differentiation of the mesophyll and its coordinated expansion is important to leaf function because light interception by chloroplasts and gas exchange in the internal airspaces of the leaf are crucial to optimise rates of photosynthesis. The spongy mesophyll layer is located directly below the palisade mesophyll layer. As spongy mentioned, the mesophyll layer is composed of through photosynthesis than those in the palisade mesophyll. In simpler terms, they are known as leaf cells. It consists of irregularly-shaped cells that are loosely packed with air spaces in between. The spongy mesophyll also allows the plant to bend and move in the wind, which itself helps move gases around the leaf's cells. The veins contain primary xylem and phloem and are enclosed by a layer of parenchyma called the bundle sheath. Leaf mesophyll composed of parenchyma tissue. The irregular spongy parenchyma also contains chloroplasts and facilitates the passage of gases through its many intercellular spaces. It lies just below the palisade layer. ; In Nymphaea plant sclereids which give mechanical support to the spongy tissue and secretory cells are also found in these cells. The spongy mesophyll is located on the bottom/underside of plant leaves, so it has less chloroplasts and aren't as rigid as the tough mesophyll. In dicotyledonous leaves there are two types of mesophyll cell; palisade mesophyll and spongy mesophyll. The spongy mesophyll cells are Jr ntr rakhi photosynthesis likely to go two types of cells. if yes, is it safe to say: when CO2 enters the leaf, through the stomata, it goes through air space, into the spongy mesophyll and palisade mesophyll? Also called spongy mesophyll. The chloroplasts in these cells absorb a major portion of the light energy used by the leaf. The spongy mesophyll's function is to allow for the interchange of gases (CO2) that are needed for photosynthesis. In contrast, spongy parenchyma is the lower mesophyll layer of spherical or ovoid cells with few chloroplasts and very prominent intercellular air spaces. The important functions of the spongy mesophyll are: The presence of chloroplast in the spongy mesophyll tissue also helps in performing the photosynthesis. SPONGY MESOPHYLL. A layer of cells in the interior of leaves, consisting of loosely arranged, irregularly shaped cells that have chloroplasts. In plants, it is part of the mesophyll, where it forms a layer next to the palisade cells in the leaf.
