Lab Act 2 Flashcards
What is the title of Lab Act 2
Evolution of Vegetative Structures
Part of the success of land plants was based upon the evolution of a very strong organic polymer called ________
lignin
The three lignified cells are the following:
- Tracheids
- Vessel elements
- Fibers
lignin that is first to evolve, combined the functions of support and water transport
Tracheids
lignin subsequently evolved from tracheids, specialized for water transport
Vessel elements
lignin also evolved from tracheids, cells specialized for support only
Fibers
All lignins can be found in the ________
Xylem
Which is the only lignified cell that is found in both the xylem, phloem, and other parts of the plant
Fibers
Examples of Bryophytes
Moss
Liverworts
Hornworts
Examples of Pteridophytes
Ferns
Lycopodium
Selaginella
Example of Gymnosperms
Pine
Example of Angiosperms
Tilia
