摘要指状海带的精子具有典型的雄性褐藻配子的精细结构，但缺少发育良好的叶绿体和眼斑。成熟精子器最显著的特征是细胞壁（帽）的特化肿胀和精子周围的大量粘液。这两种成分都参与了精子器的爆炸性破裂，这是由激素因素引发的。
Abstract Spermatozoids in Laminaria digitata exhibit fine-structural details typical for male brown algal gametes, except for the presence of well-developed chloroplasts and lack of an eye-spot. The most conspicuous features of mature antheridia are a specialized swelling of the cell wall (cap) and large amounts of mucilage surrounding the spermatozoid. Both components are involved in the explosive bursting of the antheridia, which is triggered by a hormonal factor.
