And Answers Latest Update 2026
almost identical to true plants &
considered the ancestors of true plants
green algae are multicellular & allow for
many evolutionary possibilities in terms
of body construction (motile/nonmotile,
list three significant attributes of green algae
filamentous, parenchymatous, etc.)
alternation of heteromorphic
generations is traced to green algae,
and theory of life cycles are discussed
through green algae
one free-living generation where specialization
what is a monobiontic lifestyle? name one type
and mitosis only occurs; the filamentous species
of alga that has this type of life cycle?
Ulothrix is monobiontic
green algae: chlorophyll a/b,
carotenoids, xanthophylls (pigments);
distinguish between the following types of algae starch (products)
in terms of photosynthetic pigments and red algae: phycobilisomes,
photosynthetic products: phycoerythrin, phycocyanin, carotenoid,
chlorophyll a (pigments, quantities of
green algae
pigment vary by depth); floridean starch
red algae (products)
brown algae brown algae: chlorophyll a/c,
xanthophyll, carotenes (pigments);
laminarin, mannitol, fats (products)
, state the life cycle of Ulva & describe the main dibiontic life cycle
characteristics of the life cycle in terms of with an
haploid and diploid generations alternation of
isomorphic
generations
where both are
free-living and
are isomorphic
1. diploid
sporophyte (2n)
produces spores
inside sporangia
by meiosis
2. spores are
haploid (n)
3. each spore
grows by mitosis
into a haploid
gametophyte (n)
4. the
gametophyte
produces
gametes (n)
5. the gametes
fuse in
fertilization to
form a diploid
zygote (2n)
6. the zygote
grows into a new
diploid
sporophyte
state the life cycle of Derbesia & describe the dibiontic life cycle
main characteristics of the life cycle in terms of with alternation
haploid and diploid generations of hetermorphic
generations
