During early stages in the transition from 1‐ to 2‐dimensional gametophyte development the change from filamentous to bulbous apical cell is not accompanied by major changes in the nature or number of cytoplasmic components of the cell. However, chloroplasts in apical cells of plants grown in red light are larger than those from cells of plants grown in blue light. In addition, the orientation of cytoplasmic microtubules is different in apical cells of plants from red and blue light. This change in orientation may be causally related to the change in apical cell form during 1‐ to 2‐dimensional growth.
