Seedless Vascular Plants
Multiple Choice
Which of the following is true of seedless vascular plants?
A
They lack vascular tissue.
B
They are primarily aquatic.
C
They have a dominant sporophyte generation.
D
They reproduce using seeds.
Verified step by step guidance1
Understand the characteristics of seedless vascular plants. These plants include ferns, horsetails, and clubmosses.
Recognize that seedless vascular plants do have vascular tissue, which includes xylem and phloem, allowing them to transport water and nutrients.
Note that seedless vascular plants are not primarily aquatic; they are typically found in moist environments but are terrestrial.
Identify the life cycle of seedless vascular plants, which is characterized by a dominant sporophyte generation. This means that the sporophyte (diploid) stage is the most visible and long-lived phase of their life cycle.
Understand that seedless vascular plants reproduce via spores, not seeds. Spores are produced by the sporophyte and can grow into a new gametophyte (haploid) generation.
