Question

Place the following words into the in order gametes, sporophyte, gametophyte, and zygote. Explain how the terms are related.

Answer 1

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.

Thank you so much!

The thing also starts at spores.
