Which of the following best describes the pith: a tissue type present in vascular plants?
Pith is a type of tissue located in the stems of vascular plants. It stores and transports nutrients throughout the plant. The pith is composed of parenchyma cells.
Compare your answer with the correct one above
Fill in the blanks.
The __________ generation is dominant in the bryophyte life cycles, and the __________ generation is dominant in seedless vascular plants.
Bryophytes are nonvascular plants, such as mosses. Gametophytes are species that have haploid cells during their mature lives, while sporophytes are predominantly diploid during their adult phases.
Bryophytes have the gametophyte generation as dominant, with the sporophytes relying on the parental gametophyte. Starting with the evolution of seedless vascular plants, the gametophytes become reduced and are no longer the dominant life cycle. By the formation of angiosperms (seed plants), the gametophytes have become dependent on the parental sporophyte.

Which of the following is not an example of an advantage gained through the vascularization of plants?
Swimming sperm is a feature of avascular and early vascular plants, who needed to remain in moist environments in order to retain water.
After gaining vascular systems, plants were able to circulate water and nutrients more efficiently, thus being able to grow larger, have more leaves, develop branched systems of roots and shoots to collect water and nutrients, and better dispersal of spores due to gains in size.

Which of the following structures would be found in a tracheophyte, but not in a bryophyte?
All plants can be classified as either bryophytes or tracheophytes. Plants that contain transport vessels (xylem and phloem) are tracheophytes, while those without transport vessels are bryophytes. All plants contain cell walls and chloroplasts, but only a tracheophyte would contain xylem. Plasmids are structures that are almost exclusively found in bacteria or protozoans.
