Prove that horsetail and sycamore are spore plants.

A specific plant can be classified as spore based on the structural features of its reproductive organs. Both horsetails and ferns reproduce by spores. These plants reproduce asexually by forming spores. In order for an adult plant to form from a spore, special conditions are necessary, in particular, a large amount of water. That is why spore species (including ferns and horsetails) are often found in those parts of the world where there is a particularly humid climate (for example, in the tropics).
