It is a haploid multicellular organism that develops from a haploid spore that has one set of chromosomes. The gametophyte is the sexual phase in the life cycle of plants and algae. It develops sex organs that … See more In some multicellular green algae (Ulva lactuca is one example), red algae and brown algae, sporophytes and gametophytes may be externally indistinguishable (isomorphic). In Ulva the gametes are See more In heterosporic plants, there are two distinct kinds of gametophytes. Because the two gametophytes differ in form and function, they are termed heteromorphic, from hetero- "different" and morph "form".

WebNov 9, 2024 · The gametophytic phase of the plant life cycle is believed to have important implications for genetic variation and plant evolution. The absence of heterozygosity in the haploid phase removes dominance effects, thereby increasing the efficacy of selection on both beneficial and deleterious mutations (Immler, 2024).Furthermore, a variety of … http://web.ncyu.edu.tw/~jstsay/botany/textbook/chinese/bchapt12.htm Web王 莉,孔凡娜,茅云翔,杨 惠 (中国海洋大学海洋生物遗传育种教育部重点实验室,山东青岛266003) 坛紫菜配子体离体细胞发育研究* buffalo express mccomb ms menu
