Diverse growth forms unicellular, colonial, filamentous. Paranoids protein structures that contain enzymes associated with starch production. Red eye sport involved with light perception. Asexual production - non flagellated, zoospores: haploid produce up to 32 individual zoospores. Sexual reproduction pairs of cells are attracted to each other zygote formed zygospore meiosis haploid organisms produced. Most of its life will be in the haploid phase predominant phase. Asexual reproduction zoospores at the tips of the filaments (n- haploid) fringed at the top flagellae () friar tuck look. Oogamy one gamete (male) is mobile and the other (female) is stationary and much larger. Male antheridium sperm cells produced. Female oogonium roundish cells 1 egg . Sperm cell from the antheridium enters a pore in the oogonium and forms a. Sexual reproduction conjugation protoplast from one filament cuters an attached cell in another filament. Zygote formed (2n) meiosis haploid cells produced. Hydrodictyum forms net like growth under eutrophic growth.
