Verified step by step guidance
1
Understand the basic characteristics of seedless vascular plants and nonvascular plants. Seedless vascular plants include ferns and horsetails, while nonvascular plants include mosses and liverworts.
Recognize that both seedless vascular and nonvascular plants do not produce seeds. Instead, they reproduce via spores.
Identify that both types of plants require water for fertilization. This is because their sperm are flagellated and need a moist environment to swim to the egg.
Differentiate between the life cycle stages: Seedless vascular plants have a dominant sporophyte generation, while nonvascular plants have a dominant gametophyte generation.
Conclude that the shared characteristics between seedless vascular and nonvascular plants are that they both lack seeds and require water for fertilization.
