Algae Flashcards
what is algae
the polyphyletic grouping of eukaryotic photosynthetic organisms
what is polyphyletic
organisms that dont share an immediate common ancestor
how are algae groups divided
class of organism of the endosymbiont type of endosymbiosis
what is an endosymbiont
organism that is engulfed and is the symbiont to a larger organism
what are the 3 main endosymbiont in algae
- cyanobacteria
- green algae
- red algae
what does the green algae group include
- modern day green algae
- plants
- red algae
- glaucophytes
what is the taxon for green algae in plants
viridiplantae
what is the taxon for primary endosymbiont algae
archaeplastida
what does archaeplastida include
- terrestrial plants
- modern day green algae
- red algae
- glaucophytes
what is the closest relative to terrestrial plants
green algae
what are characteristics of green algae
- single cell
- colonial grouping of single cells
- large seaweeds
how many species of green algae exist
8000+
what do chloroplasts contain in green algae
chlorophyll a and b
what are characteristics of red algae
most are multicellular
mainly marine
how many species of red algae exist
7000+
what is the pigment in chloroplasts of red algae
phycobiliprotein
how many species of glaucophytes
around 15
characteristics of glaucophytes
freshwater species
they retain peptidoglycan layer of cyanobacteria
what are the pigments found in glaucophytes
chlorophyll a
phycobiliprotein
what is special about blue algae
its actually cyanobecteria
what is a lifecycle
the steps involved in the life and reproduction of species
what is the lifecycle in animals
gametes fuse into the zygote
diploid organism does cellular division and grows
what are the animal gametes
egg and sperm
haploid cells
what is the alteration of generation
haploid and diploid grow into multicellular organism and release haploid forms
