Answer 2

The main challenge faced by the first land plants was access to WATER. Plants responded to this challenge by developing vascular tissue to transport materials throughout the plant.

• The land plants evolved to maintain life in dry conditions because the land is an environment where water is a limited resource.

• The plant vascular tissues include phloem and xylem, which work together to move substances (including water) within the plant.

• Xylem transports water from the roots up to other plant tissues, whereas phloem moves sucrose between the leaves and other plant tissues.

In conclusion, the main challenge faced by the first land plants was access to WATER. Plants responded to this challenge by developing vascular tissue to transport materials throughout the plant.
