Probably the green algae, which descended from cyanobacteria. Seaweeds come in three colours, green, brown and red, and each has different photosynthetic mechanisms - not only chlorophyll.
The intertidal zone may have played an important part in the colonization of the land from aquatic plants.

ReneThe oldest ancestors of plants are believed to be green algae, which are aquatic organisms that share similarities with land plants. Green algae are considered the evolutionary precursors to the first land plants, which eventually evolved to become the diverse plant species we see today.

What is the most likely ancestors of green plants?
mosses
What protists are considered to be ancestors of land plants?
Green algae, particularly charophytes, are considered to be the closest relatives and ancestors of land plants. They share many characteristics with land plants, such as similar chloroplast structure and reproductive features. This close evolutionary relationship suggests that land plants evolved from green algae.
What is the sequence that represents the correct order of development of chloroplasts of modern plants from their primitive ancestors?
Cyanobacteria > Red Algae > Green Algae > Land Plants
Do plants have vestigial organ?
No, plants do not have vestigial organs. Vestigial organs are remnants of structures that were once functional in evolutionary ancestors but are no longer needed. Since plants do not have a common ancestor with animals, they do not have vestigial organs.
Was man created before the plants or after the plants?
According to the Bible, man was created after plants. In Genesis 1, God created plants on the third day and then created man on the sixth day.
