Chapter 29

Explain why vascular plants are better able to sustain photosynthesis than are bryophytes.

Explain why transpiration is best explained as a consequence of acquiring \(\mathrm{CO}_{2}\) from the atmosphere as opposed to temperature regulation, nutrient transport, or utilization of water as a substrate in Photosynthesis.

Contrast how transport is generated in xylem and in phloem.

Describe the structure of xylem conduits and sieve tubes in relation to their function.

Explain why phloem is necessary to produce root.
