vascular tissue - Answer -System of vessels that interconnects a large extensive body
-allows plants to live on dry land
Xylem - Answer -Vascular tissue that transports water
-flows up w/ evaporation
Phloem - Answer -Transports carbohydrates
-flows by gravity
Amount of vascular tissue determines.. - Answer -1. The size of the plant
2. How close to water the plant must live
