Question: Dominant form in bryophyte life cycle ⼀Answer:
Gametophyte
Question: Do bryophyte sporophyte and gametophyte live
independently? ⼀Answer: No, sporophyte is dependent on gametophyte
Question: Red algae vs. Green plants ⼀Answer: Red algae chlorophyll
A only, green algae chlorophyll A and B. Red algae varies from single celled
organisms to complex multicellular organisms.
Question: Streptophyte Synapamorphies ⼀Answer: retention of egg in
parental organisms, apical growth, oogamy, plasmodesmata
Question: Plasmodesmata ⼀Answer: small holes/ channels that make
water transport much easier
, 3 Exampromax - Stuvia US 2025/2026
Question: Parenchyma ⼀Answer: Basic tissue type in the streptophytes
with cells linked by plasmodesmata
Question: Land plant synapamorphies ⼀Answer: cuticle, stomata,
gametangia, embryo, pigments, sporopollenin, mycorrhizae
Question: Cuticle ⼀Answer: a waxy coating that protects from water
loss, disease, sun and organisms who are predators
Question: Stomata ⼀Answer: small openings that allow for gas

exchange in air while minimizing water loss

Question: Sporopollenin ⼀Answer: protective coating for spores
Question: Mycorrhizae plants ⼀Answer: Plants that have mutually
beneficial association with fungi, fungi attach to plant roots and increase
surface area of roots allowing for more water to be taken up throught the
plant
Question: Groups of plants within the bryophytes ⼀Answer: liverworts,
horntails and mosses
Question: Are bryophytes a clade? ⼀Answer: NO!
Question: Primary characteristics of bryophytes ⼀Answer: no vascular
system, very small, no structure to keep them off the ground, no structure to
transfer food and water through the plant
, 4 Exampromax - Stuvia US 2025/2026
Question: Why do bryophytes tend to live in moist habitats? ⼀Answer:
bryophytes move nutrients through diffusion and osmosis so they have to be
near water to survive
Question: Dominant form in the bryophyte life cycle ⼀Answer:
Gametophyte
Question: Can bryophyte sporophytes and gametophytes live
indepedently? ⼀Answer: No. Sporophyte is physiologically dependent on
the gametophyte.

Question: Where are bryophyte gametes produced? ⼀Answer:
Archegonium (female sex organ) and antheridium (male sex organ)
Question: How are gametes dispersed in bryophytes? ⼀Answer:
Question: Ephiphyte ⼀Answer: Organisms that live together with no
beneficial or paristic relationship. (plants growing on a tall tree). benefits are
indirect.
Question: Parisite ⼀Answer: lives off of another organisms. Not
mutually beneficial, only beneficial to one.
Question: Main characteristics of liverworts ⼀Answer: no true stomata,
rhizoids, elaters, green- flat like gametophyte, sporophyte remains attached
to the larger gametophyte, can reproduce sexually or asexually, no internal
water conduction; differ from other bryophytes in the fact that they do not
have a true stomata and other bryophytes do
