Under what conditions can the most primitive plant form survive?

You will have to be more specific. What exactly do you mean by primitive
plants? If you mean one-celled plants, most of them are found in water. If you
mean primitive land plants, that usually means the mosses and their relatives.
Since their primitive structure lacks sophisticated water transporting
capability, they are mostly adapted to shady locations with a constant supply
of moisture.

Well, pretty primitive conditions.
PvR

PS: define "survive", "primitive" and especially "plant" and "form".
Perhaps also "conditions".

Usually in some isolated protected area such a canyon or island. Look for
them in these places, though by definition it will be tough going.

This is too poorly defined a question to be answered as is.
What exactly do you want to know?

What are the modern habitats of the living, modern
members of the earliest branch lineages of the [land]
plants? Bryophytes occupy a diverse range of envirionments,
but liverworts, etc. typically like it shady and moist.

or, what were the habitats of the early common ancestors of
all modern [land] plants like?

"Primitive" strictly should mean "retaining characteristics of
[some particular] common ancestor", and really would best be
examined feature by feature. None of the modern descendants
of the first embryophytes is likely to be much like their
Silurian ancestors.

Horsetails and scouring rushes (Equisetum spp.) are quite primitive
and appear to be able to survive just about any conditions short of a
direct hit with tactical nukes.

Resaw the first episode of "The private life of plants" last night, and they
showed a Magnolia seed that survived for 2000 years to germinate and yield a
small tree.

So, IIUC: primitive plants are not sociable?

Magnolia is a primitive dicot, but I would hardly call it a primitive plant.

Magnolia is indeed a primitive Angiosperm (not sure about dicot), but with
both "primitive" and "plant" undefined this statement is as good as any, and
at least is informative?
