During cell division in apical meristem, the nuclear membrane appears in (a) telophase (b) cytokinesis (c) metaphase (d) anaphase.
Suppose the pH in the cell walls of an apical meristem became highly basic ( > pH 7), but traffic through PIN proteins in the membrane remained normal. Where would you expect most auxin molecules to be concentrated—in the cell wall or cytoplasm? Would the auxin molecules be in the charged or uncharged form? a)cell wall; uncharged form b)cell wall; charged form c)cytoplasm; charged form d)cytoplasm; uncharged form This is all the information I was provided.
