WebDec 4, 2024 · In the brown algae genus Laminaria, haploid spores develop into multicellular gametophytes, which produce haploid gametes that combine to produce diploid organisms that then become multicellular organisms with a different structure from the haploid form (Figure 28.6.11 ). WebThe asexual reproduction of the gametophytes takes place by neutral spores, monospores, and polyspores. The neutral spores develop in ordinary cells of thallus, e.g., Asterocystis. The monospores are developed in sporangia. A single spore develops in each sporangium, e.g., Scinaia. The polyspores are formed in larger number in the sporangium. csun grad school cost
