triphasic life cycle - ANS what kind of life cycle do rhodophytes have
gametophyte, tetrasporophyte, carposporophyte - ANS Rhodophyte triphasic life cycle
phases
oogamy - ANS sexual reproduction of rhodophyta
primary endosymbiotic event - ANS rhodophyta are descendents of which endosymbiotic
event

ancestry with

, epiphyte, epizooic, epilithic, psammophilic - ANS rhodophyta are hard bottom habitats,
where do they like to grow?
alloparasite, adelphoparasite - ANS two types of red algal parasites
alloparasite - ANS what type of red algae parasite is if the taxa are unrelated
adelphoparasite - ANS what type of red algae parasite is is if growing on a closely related
form from the same family
chlorophyll a, R-phycoerythrin, R-phycocyanin, R-allophycoyanin, carotenoids - ANS What
pigments are found in red alga
R-Phycoerythrin - ANS which pigment of red algae is very efficient in collecting BG light in
subtidal habitats and is also very abundant in the plastid
phycobilisomes on the surface of the unstacked thylakoids - ANS where are the
phycobilisomes in red algae located
2 plastid membranes - ANS how many plastid membranes do rhodophytes have
amylose, the unbranched fraction of green algal starch - ANS Floridean starch, food reserve
for rhodophytes is similar to glycogen or branched amylopectin fraction of green algal & higher
plant starch but lacks what
floridoside - ANS which floridean starch, low-molecular mass carbohydrate has an
osmoregulatory function
