The sporangia produce very tiny spores. Spores are different to seeds. They do not contain plant embryos or food stores. When the sporangia break open, the spores are released and dispersed by the wind.If the spore lands in a suitable environment, it can grow into a tiny plant called a gametophyte.he sporangia produce very tiny spores.

Introduction. The plant life cycle begins with a seed. The seed will sprout and produce a tiny, immature plant called a seedling. The seedling will grow to adulthood and form a mature plant. The mature plant will reproduce by forming new seeds which will begin the next life cycle. As described above this life cycle is generally used by the flowering plants. The flowering plants include trees, grasses, shrubs, and, of course, flowers. There are also lower types of plants including ferns and mosses. These also have a life cycle but they do not produce seeds. They produce a different type of reproductive cells called spores.
