Answer:
Tracheophytes are distinguished from bryophytes by their highly developed vascular systems, which facilitate the transport of water and nutrients to all parts of the plant. This vascularization adaptation has allowed tracheophytes to become more fully terrestrial than bryophytes, which are still dependent upon moist environments for many reproductive and nutritive functions, as discussed in Bryophytes. Tracheophytes can be broken down into three classes: ferns, gymnosperms, and angiosperms
<span>B) photosynthesis; cellular respiration
Photosynthesis is the process of how plants make their food. They use sun's light, water and CO2 to make glucose and turn it into energy.
