Rhodophyceae
These food additives commonly derive from Rhodophytes (2 answers).
What are pectin and agar?
This organelle, designed to assist in carbo-fixation, contained within the plastids of Chlorarachinophytes, and many other algae, appears under light microscopes as a region of pale green.
What is the Pyrrenoid?
A light-sensitive organelle found outside of the chloroplasts in euglenoids.
What is an eyespot?
Name for the oldest confirmed fossil structures, believed to be produced by basal cyanobacteria; some can still be found today in Shark Bay, Australia.
What are stromatolites?
Lifecycle type where meiosis occurs immediately after the formation of the zygote.
What is Haplontic?
Named for the "land of the flowers", this lineage contains most of the complex multicellular red algae
What is the Florideophyceae?
These two traits can separate Chlorarachniophytes from chlorophytes (2 answers).
What are anastomosing pseudopodia and 4 membranes around the chloroplasts?
This number of structures in Euglenoids makes them appear rather unusual in the evolution of photosynthetic organisms.
What are chloroplast membranes?
These specialized cells in cyanobacteria colonies or multicellular organisms allow for them to fix nitrogen.
What are heterocysts?
A type of algal morphology where a filamentous organism can approximate a truly differentiated multicellular body.
What is pseudo-parenchymous?
Reef-forming red algae have cells with cell walls composed of a cellulose base and this common oceanic mineral.
What is Calcium Carbonate?
The two types of chlorophyll present in the chloroplasts of chlorarachniophytes.
What are chlorophyll a and b?
Euglenoids, as organisms that photosynthesize and eat other algae, can be referred to as this term.
What are mixotrophs?
Name of the phycobilin pigment where the common name for these prokaryotes derives from.
What is phycocyanin?
Euglenoids are dissimilar to other Excavates in their habit of photosynthesizing; most other members of this supergroup, including the infamous Trypanosomes, perform this niche instead.
What are parasites?
This genus of red algae close relative contains flagella, demonstrating that they too shared the trait ancestrally.
What is Rhodelphus?
Name of the genus where the only other primary endosymbiotic event outside of Archeaplastida occurred.
What is Paullinella?
What is paramylon?
What is Phycoerythrin?
A term that describes in totality the group of algae living at the bottom of photosynthetically active regions, or phytobenthos.
What is Periphyton?
This red alga, commonly known as nori, shows a haplodiplontic lifecycle with two distinct stages.
What is Porphyra?
This is the chemical formula for the compound forming the skeletal base of the Chlorarachniophytes.
The canal at the apex of a euglenoid leads not to a true mouth, but instead to this osmotic maintaining organelle.
What is the contractile vacuole?
This process creates genetic diversity in cyanobacteria and even allows them to exchange genes with Eukaryotes.
What is Horizontal Gene Transfer?
Many archeologists use the remnants of this algae to date and determine the locations of archaic pottery.
What are Diatoms?
