Sporophyte, spores, gametophyte, gametes.
Or gametophyte, gametes, sporophytes, spores.
It depends on how we look at the life cycle of plants i.e. whether we want to start from a zygote or from a spore.
Some plants (fern, for example) have alternation of generation in life cycle, which is a regular alternation between two distinct life forms. Sporophyte and gametophyte and the general distinct life forms in most plants.
The sporophyte life form is derived from a zygote. Once the sporophyte matures, it produces numerous spores.
The produced spores later develop into a heart-shaped structure called "prothallus." This marks the start of the gametophyte stage.
The prothallus contains both female and male parts and release the respective sex cells/gametes, which fuse to form a zygote.
The zygote develops into a new plant of its own which later produces spores once more, starting the sporophyte stage.
Place the following words into the in order gametes, sporophyte, gametophyte, and zygote. Explain how the terms are related.

Thank you so much!
The thing also starts at spores.
