Identify three similarities between a prokaryotic and eukaryotic cell. Larger amounts of water can pass through the membrane more quickly via membrane channel proteins called aquaporins. Programmed cell death in plants occurs by a process called autolysis (auto-lysis). It allows for the production, folding, quality control and dispatch of some proteins. Light independent reactions happen in the stroma. Water entering will be equal to water leaving cell The mechanism keeps the plant from wilting and plays a key role in the water balance. The tonoplast does not regulate the entrances and exits to cells, however, but instead acts as the guard for what kinds of matter are allowed passage to and from vacuoles. Vacuoles and/or lysosomes in eukaryotic cells are generally defined as acidic compartments containing hydrolytic enzymes that can digest and recycle all types of biomolecule. Vacuoles in animal cells also serve to isolate and remove harmful pathogens. Viral infectionslead to vacuole membrane breakage and release enzymes into the cytosol, where they can attack viruses. What is the structure of the inner membrane (cristae) of the mitochondria? Maintaining constant osmotic pressure in the fluids of an organism by the control of water and salt One point that can be confusing is the difference between lysosomes and peroxisomes.
