Speculative biology is simultaneously a science and form of art in which one speculates on the possibilities of life and evolution. What could the world look like if dinosaurs had never gone extinct? What could alien lifeforms look like? What kinds of plants and animals might exist in the far future? These questions and more are tackled by speculative biologists, and the Speculative Evolution welcomes all relevant ideas, inquiries, and world-building projects alike. With a member base comprising users from across the world, our community is the largest and longest-running place of gathering for speculative biologists on the web.

Plant world; A world without animals

I came with another speculative world.

What if plants became the dominant group of organisms because animals would have somehow never evolved or have gotten extinct in a very early stage of evolution.

Would it in this case be possible for plants to evolve a nervous system and even evolve animal-like forms?

Other major groups would be Bacteria and other microbe based growths along with maybe Ediacarans which are not true animals some even looked like Plants.

Though moving slime molds would be the top predators of plants at least at first any way.

So are we hypothesising that all these plants would be sessile? No moving, swimming plants? Shame... :(

there wouldn't be any danger to a moving plant, and being mobile would benefit the plant. it is just that no one has bothered with the idea in a serious way...
Oh Fine.

Plants are mobile, sort of.
They move(Grow) upwards and downward with their roots and sometimes sideways, if they're vines.

My sci-fi story is set on a planet(Actually a planet-sized moon) named Zeta: One on the continets covers a large expanse from northern polar regiaons to southern polar regions. I felt their, especially, migration would be very important for critter.

After thinking about it for a bit, I thought, why not plants, too? If they grow along the ground; they could follow the sun as it travels north to south and back again due to the axial tilt.

O.K. Just one thing... PLANTS DO NOT HAVE ANY KIND OF MUSSEL OR EQUIVELENT! How are they going to move?

they can use hydrolics like a sensitive plant. you don't need muscles to move, i mean, they could even have a tube made of rings that can be charged with electricity and move a pole that in in the tube by attracting it to each ring(turn the ring on and the pole moves toward it, turn the next ring on and the current one off and the pole moves further)... ions and such...
Oh Fine.

That'd be a fairly high-energy activity, wouldn't it?

Question: Would these moving plants have anything rsembling fat; for endurance work? Or will it be scrictly a case of short-term activity only?

If you can think of a substence that would work like fat in plants and how it wold evolve you can use it.

I guess we'd need to know the chemical make up of fat.
Perhaps it's possible for plants to extract the chemicals required from around them. How quickly they could do so might influence things.

how about just have them make fat? plants make oils and the all cells make lipids (to my knowledge) so i don't see why not, although starch is more likely what they will produce...

also by a sensitive plant i meant the real thing in case anyone didn't understand
