They are individual cellular organisms but they’re not molecules. Individual molecular structures are too small for light to interact with so no matter how much you magnify them you’re never going to see them.
That’s why things like electron microscopes were invented. You can’t just build bigger and more powerful microscopes it doesn’t work.

Err, I don’t think that’s right. That’s physically impossible. Only electrons are small enough to visualise molecules and atoms, which is why you need electron microscope to see those.

Whoa, my optometrist tips me that’s what they are and now I’m really disappointed.
Considering their shape and what you said about them being impossible to observe in visible light… I guess those branch-like pieces are cell organelle fragments instead?
Dang, and here I was excited to be seeing molecules.

You can see cells with the naked eye as well. Notably, eggs. Chicken eggs are also one cell. The largest cell is an ostrich egg.

There are amoebas that reach 5mm in length.
IIRC, there are limits on how big they can get based on how far RNA can travel after copying DNA.

Don’t forget about Valonia ventricosa as well!
