Phloem cells are specialised to transport the products of photosynthesis around the plant. Given the lack of palisade-form cells, we modelled all mesophyll cells as spheres for these calculations. Test. Palisade cells contain the largest number of chloroplasts per cell, which makes them the primary site of photosynthesis in the leaves of those plants that contain them, converting the energy in light to the chemical energy of carbohydrates. Designed to be used for the OCR AS Biology course in combination with the course textbook. Every batch of sperm represents an opportunity for genetic typos – called de novo mutations – to be passed on. The chloroplasts in these cells absorb a major portion of the light energy used by the leaf. Palisade cells are found in the mesophyll of a leaf and their main function is the absorption of light so that photosynthesis can take place. cell-specialisation-jesse.wikispaces: Cell wall This is needed in a plant cell to offer structural support, stop cells bursting and provide the symplastic pathway for water movement. -Palisade tissue (layer of palisade cells within the leaf) -Root tissue Organs Organs are made up of several types of tissue grouped together, for example, the small intestine is made up of muscle tissue, connective tissue, epithelial lining tissue and also nerve tissue to control its action.
