Types of Spores. Spores are very common and depending on the type of organism that made them, they can look and act very different. Spores can be classified in many different ways based on their structure, where they come from, and how they move about the world.he major types of plants that form spores are algae, mosses, and ferns.

The spores from all algae are very tiny, even if the algae plant is huge.
