Leaf palisade cell=>long, thin, forms a continuous layer to absorb sunlight, lots of chloroplasts, large vacuole to push chloroplasts to edge of cell
Chloroplasts=> Chloroplast envelope (double plasma membrane) , Grana (stacks of Thylakoids), Thylakoids contain Chlorophyll with tubular extensions to other Grana-> where 1st stage of photosynthesis takes place, and the Stroma (Fluid filled matrix, where 2nd stage of photosynthesis takes place)
They carry out photosynthesis because... Grana= large surface area so chlorophyll, enzymes and electrom carriers can attach to, Fluid od stroma has enzymes for 2nd stage of photosynthesis, Chloroplasts contain both DNA and Ribosomes so proteins are easily manufactured at will
Cell wall=>Made of cellulose and other polysaccharides, and the middle lamella cements adjacent cells together ==>They provide strength to stop the cell bursting, give strength to the plant as a whole and allows water to travel through the plant
