All about fruitarianism with a long-term fruitarian, Lena

Forest trees and their root fungi share resources and information. The plant makes and delivers food to the fungus; the fungus increases the plant’s water and mineral absorptive powers. Trees of different species can communicate with and support one another via their mycorrhizae. 

It is known, that plants can communicate with unrelated species through the air. Plants getting chomped by herbivores, eaten by insects or attacked by pathogens release volatile chemicals that are sensed by neighboring plants, who up their defenses pro-actively.

Richard Dawkins

I'd like everybody to be a vegetarian... In 100 or 200 years time, we may look back on the way we treated animals today as something like we today look back on the way our forefathers treated slaves.

Protists

Protists - members of an informal grouping of diverse eukaryotic organisms that are not animals, plants or fungi, and are grouped together for convenience, like algae or invertebrates. Besides their relatively simple levels of organization, protists do not necessarily have much in common. 

Subdivisions of Protists

Protozoa the unicellular "animal-like" - Flagellata, Ciliophora, Amoeba, Sporozoans.

Protophyta the "plant-like" - mostly unicellular algae.

Molds the "fungus-like" - slime molds and water molds.
