I suppose it's a zygote. In haplontic life cycle haploid gametes fuse together creating the zygote (diploid) that promptly divides meiotically creating 4 haplontic cells serving as spores.
Symbiosis is a close relationship between two species in which at least one species benefits. For the other species, the relationship may be positive, negative, or neutral. There are three basic types of symbiosis: mutualism, commensalism, and parasitism.

Mutualism is a symbiotic relationship in which both species benefit. An example of mutualism involves goby fish and shrimp
Phototropism as photo means light
eg: photosynthesis
