Club mosses, horestails and ferns are types of vascular seedless plants. These types of plants reproduce through spores rather than the fertilization of seeds. The weight of spores is much lighter than that of seeds. These plants also require ample water for fertilization. The combination of light wind and moisture that is needed for reproduction means that you will often find these plants in damp or wet areas. Thinking of how mosses and horsetails are found in wetter areas will help you to remember this.
The contractile ring shrinks through the center of the cell, evenly dividing the cytoplasm between the two halves. This indicates that cytokinesis is completed and the cell has been replicated.
