Arrange the stages of non-flowering plant reproduction in order:

Gametes Sporophyte Spores Gametophyte Zygote

Spores Gametophyte Gametes Zygote Sporophyte

The correct order of the stages of non-flowering plant reproduction is as follows:

1. Sporophyte
2. Spores
3. Gametophyte
4. Gametes
5. Zygote

To arrange the stages of non-flowering plant reproduction in order, we need to understand the process of non-flowering plant reproduction. Let's start with a brief explanation of each stage:

1. Sporophyte: The sporophyte is the diploid, or two sets of chromosomes, phase of a non-flowering plant. It is the dominant and visible stage of the life cycle. The sporophyte produces structures called sporangia.

2. Spores: Sporangia are structures produced by the sporophyte that contain spores. Spores are single-celled structures that are capable of growing into a new plant. They are haploid, meaning they contain only one set of chromosomes.

3. Gametophyte: Spores germinate and develop into the gametophyte stage. The gametophyte is a haploid stage that produces gametes. The gametophyte is often smaller and less visible than the sporophyte.

4. Gametes: The gametophyte produces male and female gametes. Male gametes are called sperm, and female gametes are called eggs. These gametes are haploid and are necessary for sexual reproduction.

5. Zygote: The fertilization of a sperm and egg form a zygote. The zygote is the result of sexual reproduction, where the male and female gametes fuse, combining their genetic material. The zygote is diploid and has the potential to develop into a new sporophyte.

Now that we understand the stages of non-flowering plant reproduction, let's arrange them in order:

1. Sporophyte: This is the initial stage of the life cycle and the dominant phase.
2. Spores: Spores are produced by the sporophyte and are capable of growing into a new plant.
3. Gametophyte: Spores germinate and develop into the gametophyte stage.
4. Gametes: The gametophyte produces male and female gametes.
5. Zygote: The fusion of sperm and egg forms a zygote.

So, the correct order is:
Sporophyte -> Spores -> Gametophyte -> Gametes -> Zygote
