Question

how is the life cycle of seedless vascular plants different from the life cycle of nonvascular plants?
the adult form of each seedless vascular plant has xylem and phloem.
the gametophyte stage is lacking in the life cycle of seedless vascular plants.
the sperm of seedless vascular plants do not need to swim in water.
the zygote of each seedless vascular plant forms before the egg is fertilized.

Explanation:

• Nonvascular plants lack vascular tissues (xylem and phloem). Seedless vascular plants, as the name suggests, have vascular tissues (xylem and phloem) in their adult form.
• Seedless vascular plants do have a gametophyte stage.
• The sperm of seedless vascular plants still need water to swim to the egg for fertilization.
• A zygote is formed after the egg is fertilized, not before.

Answer:

The adult form of each seedless vascular plant has xylem and phloem.
