UCF BIO 2 Exam 3 Questions And Answers
Bryophyte: -
correct answer ✅-closest relative on terrestrial plants (old)
-nonvascular plant (lack xylem and phloem)
-haploid gametophyte dominant lifecycle (1n)
-water dependent for reproduction (sperm can swim to egg)
-has thallus and rhizoids (must remain very small)
-no tracheids (vascular tissue that transports water)
-Ex. liverworts, moss, hornwarts
seedless vascular plants: -
correct answer ✅-vascular: has xylem (transports water) and
phloem (transport sugar)
-sporophyte dominant life cycle (2n)
-lignin in cell wall
-heterosporous
-water dependent for reproduction
-no seeds, fruits, or flowers
-Ex. ferns, horsetails
Gymnosperm: -
correct answer ✅-vascular, has xylem and phloem
, UCF BIO 2 Exam 3 Questions And Answers
-naked seeds
-pollinated by wind (not by animals)
-pollen cones
-tracheids
- 2 sperms; one creates pollen tube and one fertilizes egg
-Ex. Conifers, Cycads, Gingkophytes, Gnetophytes
Angiosperm: -
correct answer ✅-closed seed
-pollinated by wind insects and animals
-vascular, seed plant
-produce flowers and fruit
-Double fertilization, 1 sperm fuzes with egg; the other fuses with
polar nuclei (creates endosperm)
