Experiment to show the effect of Temperature on membrane permeability In beetroot Joseph Colledge Introduction Plants are unique among the eukaryotic organisms whose cells have membrane enclosed nuclei and organelles, because they can manufacture their own food. Chlorophyll, which gives plants their green colour, enables them to use sunlight to convert water and carbon dioxide into sugars and carbohydrates, chemicals the cell uses for fuel. Like the fungi, another kingdom of eukaryotes, plant cells have retained the protective cell wall structure of their prokaryotic ancestors. The basic plant cell shares a similar construction with the typical eukaryote cell, but does not have centrioles, lysosomes, intermediate filaments, cilia, or flagella, as does the animal cell. (Reed 1998) Plant cells do, however, have a number of other specialized structures, including a rigid cell wall, central vacuole, plasmodesmata, and chloroplasts. In prokaryotes and plants, the plasma membrane is an inner layer of protection since a rigid...
