The cork is impermeable to gaseous diffusion but the numerous lenticels (403–406) facilitate the movement of oxygen into the living tissues within this barrier and also allow the exit of carbon dioxide. Water dispersal is much less common but the large fruits of Cocos nucifera (coconut) and Lodoicea maldavica (sea coconut) are dispersed in the ocean currents with their enclosed seeds protected by a thick and sclerified endocarp. Alternation of generations In all land plants the diploid sporophyte generation is different in form to the haploid gametophyte (heteromorphic alternation).260 Glossary Abaxial surface The surface of leaf or bud primordium remote from the shoot apex or stem (cf. but numerous strands 1 of endoplasmic reticulum (3) lie in the cytoplasm together with other organelles. 269 .
