The photosynthetic descendants of this ancient protist evolved into what two things?
- ANSWERred and green algae
Land plants are descended from? - ANSWERgreen algae
which algae is a descendant from chlorophytes and charophytes - ANSWERgreen
algae
reddish in color due to an accessory pigment called phycoerythrin, which masks the
green of chlorophyll - ANSWERred algae

largest
red algae are found in - ANSWERcoastal and tropic waters
an example of red algae is - ANSWERsea weed aka nori
Charophytes - ANSWERmost closely related to land plants
Most chlorophytes live in - ANSWERfresh water, although many are marine
Other chlorophytes live in - ANSWERdamp soil, as symbionts in lichens, or in
environments exposed to intense visible and ultraviolet radiation
Larger size and greater complexity evolved in chlorophytes by what three steps -
ANSWER1.The formation of colonies from individual cells (e.g., Volvox)
2.The formation of true multicellular bodies by cell division and differentiation (e.g.,
Ulva)
3.The repeated division of nuclei with no cytoplasmic division (e.g., Caulerpa)
