When and how did plants first come about?
First plants appeared on land around 434 Million years ago, in the Paleozoic era. Or at least that's what the fossil records show. How? By evolving
from green algae, from which they inherited photosynthesis.

Obviously they couldn't have walked out of the ooze and multiply.
If by ooze you mean the oceans, no, plants didn't walk out of the ocean. But plants can move, directly and indirectly through spores and seeds. I
assume that plants or algae living on shores could have made the tranzition to land quite easily, since they don't breathe like animals do...

Wikipedia says no:
The first known footprints on land date to 530 Ma, indicating that early animal explorations may have predated the development of terrestrial
plants.

Evolution and adaptation and time, lots of time, just like the rest of us.
