plants evolved from first multicellular animals, thats why both are multicellular

fungi did this too

multicellularity began only once

this also explains why all three have so similar form:

>primitive cnidarians look like plants
>fungus look like primitive animals altough non moving
>plants resemble the animals the most
>first multicellular animals branch like trees

what went different is that plants have those chloroplasts to use light as a source of energy, this didnt happen in fungi or animals

the chromosomal DNA (not inside mitochondria) was at first the same for animals, plants and fungi, and this DNA is what creates the form, hwich is why all three look like plants

much much later evolution gave a head region to animals (fish, insect) and they became radically different from plants and fungi, in form

Plants are incredibly intricate. Imagine if you needed adaptable survivability without getting up and moving. Also, the fact that they utilize sunlight is responsible for all other life to not have to. My favorite factoid is how it's almost certain that desire for alcohol probably springboarded agriculture. Coffee gave a bump in mathematic discovery, and psychotropics likely sparked multiple religions. Plants are more in charge than we think.

>multicellularity began only once
Nope, it's happened many times. Eukaryotes probably just evolved once, and the common ancestor of plants and animals was a single celled organism, one population then eovled with a cyanobacteria, which became chloroplast. Then both groups evolved multicellularity multiple times over.

The jump from prokaryote to eukaryote seems much harder than eukaryote to multicellularity.

theres a single cell organism that looks like a plant and can reach 10 ft long
