Chapter 31, Problem 6TY
Summary Introduction
Introduction: There are various adaptations in land plants such as roots, waxy cuticle, stomata and so on. These adaptations perform different functions such as anchoring of plant into the soil, transportation of water into the plant body, and also help in process like photosynthesis.

Students have asked these similar questions
Guttation in plants is due to condensation of water vapor and occurs through the hydathodes.
D. Disagree, because guttation occurs through the stomates.
A. Agree, because guttation occurs through the hydathodes.
B. Disagree, because it is root pressure that causes guttation.
C. Agree, because during night time, water condenses due to drop in temperature.
A waxy cuticle is an adaptation thata. helps to prevent water loss from tracheophytes.b. helps to prevent water loss from streptophyte algae.c. helps to prevent water loss from bryophytes.d. aids in water transport within the bodies of vascular plants.e. does all of the above.
Water movement through the xylem needs less pressure than movement through living cells.
A. Agree, because water moves in xylem through diffusion.
B. Disagree, because water needs turgor pressure in order to diffuse.
D. Disagree, beacuse both need equal pressure for materials to pass through xylem and living cells like sievetubes.
C. Agree, because water is non-living while photosynthates are living and must pass through living cells that require pressure.
