Why do scientists study green algae along with land
plants? - ANSWER-1. They are the closest living relative
to land plants and form a monophyletic group
2 Transition from aquatic to terrestrial life occured when
land plants evolved from green algae
How do plants reproduce in dry conditions? - ANSWER-1.
Gametes are produced in protected structures
(gametangia) to prevent drying and mechanical damage
2. Land plants as embryophytes
,Name the six main developments allowing for life on land -
ANSWER-1. Cuticle
2. Stomata
3. Vascular Tissue
4. Gametes produced in complex structures (gametangia)
5. Embryo is retained and nourished by parent
6. Alternation of generations
Alternation of Generations - ANSWER-Haploid
gametophytes produces gametes by mitosis which fuse to
form a zygote and grow into a diploid sporophyte which
produces haploid spores by meiosis that grow back into
the haploid gametophyte.
, Sporophyte vs. Gametophyte dominant - ANSWER-In
mosses the gametophyte is large and long lived,
sporphyte depends on gametophyte for nutrition.
In ferns, the sporophyte is large and long lived but when
young depends on gametophyte for nutrition
Why did the transition from gametophyte-dominant to
sporophyte-dominant occur? - ANSWER-Scientists
hypothesize diploid cells can respond to varying
environmental conditions more effectively than haploid
cells, particularily if individual is heterozygous for many
genes
What are four characteristics of seed plants - ANSWER-1.
Sporophyte-dominant life cycles
