Macroalgae vs. Plants

[MombasaLionfish]

What is the difference between the two?
Macroalgae:

Plants:

Algae is a plant but not all plants are algae ...but I’m sure there is a phylum / kingdom phylogenetic type answer out there somewhere

Someone told me once that the difference between them is plants have leaves roots/holdfast and stems don't macroalgae too?

I always tough they were the same, just different water.

No because there are freshwater plants that are called plants.

Plants are a single lineage that branched off from the green algae Chara 550-750 mya. Plants (plantae) are a monophyletic group which means they all have a common ancestor. Algae is a catch all for just about anything that photosynthesizes it has nothing to do with taxonomy or evolutionary history. Green algae and red algae share a common ancestor which diverged well before plants and Chara. Both green and red algae have primary chloroplasts in other words their common ancestor first picked up a photosynthetic cyanobacteria, which became the chloroplast. Brown algae, diatoms, dinos and a bunch of other algae are from a very different lineage Stramenopiles . They are photosynthetic because they picked up a red algae cell these are called secondary chloroplasts (there are also tertiary chloroplasts but lets not go crazy). Basic phylogeny showing the positions of these groups.

Not sure if this is what you were looking for sorry if it wasn't.

So your saying this is wrong?

To move to purely hobbyist perspective. You will spend a lot more money growing plants [emoji23]
