Subsequently, question is, what process occurs at the Palisade Mesophyll? The midrib is biconvex. How does the structure of the palisade cell adapted for photosynthesis? The spongy parenchyma have large spaces between cells and contain less chloroplasts, serving as a system for gas exchanges in the plant. Palisade layer definition is - a layer of columnar cells rich in chloroplasts found beneath the upper epidermis of foliage leaves —called also palisade mesophyll, palisade parenchyma, palisade tissue. In most leaves, the primary photosynthetic tissue, the palisade mesophyll, is located on the upper side of the blade or lamina of the leaf but in some species, including the mature foliage of Eucalyptus, palisade mesophyll is present on both sides and the leaves are said to be isobilateral. The layer of Spongy Mesophyll beneath has many air spaces to maximise gas circulation. The cells: are packed with many chloroplasts. In National 5 Biology find out about the specialised systems that absorb water and food in plants and transport them around. Whats people lookup in this blog: 1.

The chloroplasts perform the process of converting energy from the sun into sugars which fuel the plant. 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. 2. Why does most photosynthesis occur in the palisade layer? Palisade and spongy mesophyll cells are sub-tissues that have different morphologies and physiologies. They are near the upper surface of the leaf to maximize the light interception.
