Vascular seed plants
300
What is phototropism?
Plant responds to light
300
What is the dominant life stage of a nonvascular plant?
Gametophyte (haploid)
400
Which hormone is associated with fruit ripening?
Ethylene

What does it mean when a plant is vascular?
It has vessels
The plant can grow taller because vessels can bring water and nutrient up from the soil to the leaves.
