Archaeplastida

Algae

Any aquatic photosynthetic eukaryote that is not a land plant

Not a clade cause its not monophyletic

Algae in Archaeplastida

Red Algae

Chlorophyta green algae

Charophyta green algae

Algae not in Archaeplastida

Brown Algae

Golden Algae

Dinoflagellates

Diatoms

Which Pigments are common in all plants and do they give info about their phylogeny??

Chlorophyll a, carotenes, and xanthophylls

They don’t give much info about their phylogeny

What is Accessory Pigments and do they give info about the phylogeny of archaeplastida??

Pigments that work with chlorophyll a including chlorophyll b, c, d, and phycobilins

They give more info about its phylogeny

What is the difference b/w green algae and land plants??

Water and Mineral Source

Source of CO2

Structural Support

Plant Adaptations to life on land

Sporopollenin

Resistent to drying and is a polymer

Land plants use it in their spore walls

Protects charophyte zygotes from drying out

Sporophyte

Multicellular diploid stage

Gametophyte

Multicellular haploid stage

Embryophytes

Retention and protection of land plant embryos within female gametophyte tissue

Adaptation which prevents embryo dessication

Sporangium

Found in sporophyte generation, moss sporophytes, and soras in ferns

Walled spores are made through mitosis in this structure

How are gametes produced??

Produced by a multicellular gametotangium and through mitosis

Found in the gametophyte generation

What are Apical Meristems???

Allows plants to exploit resources in terrestrial environment

Shoot and Root Growth is maintained
