Chapter 29

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 the use 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 roots.

List four adaptations of roots that enhance the uptake of nutrients from the soil.
