This diagram shows the life cycle of a fern.
A circular diagram shows the life stages of a fern. The first stage is labeled "spore starting to grow" and shows a small green plant with a few roots. The next stage is labeled "heart-shaped plant" and shows a small, flat plant in the shape of a heart with roots extending from the bottom. Next, a close-up of the heart-shaped plant shows two structures. One of them is bumpy and circular with small dots labeled "sperm" coming out of it. The sperm are falling into the second structure, which is shaped like a vase with a circular structure labeled "egg" at the bottom. The next stage is labeled "fern plant starting to grow" and shows a slender stalk with a single leaf growing up out of the heart-shaped plant. The final stage is labeled "mature fern plant" and shows a long stalk with many small leaves extending from the sides. Small, circular structures labeled "spores" are coming off the leaves at the top of the plant. An arrow points back to the spore starting to grow in order to show a complete cycle.
