Acetabularia, a seaweed, consists of a single cell
a couple of inches high. I don't know how large
you mean by macroscopic, but some single celled
protozoans are large enough to see with the naked
eye.

Eggs, for example hen's eggs, frog's eggs. Also, some protozoa such as Paramecium and huge algae such as Dynoflagellates. You've got some huge cells you never see in your liver, which has polyploid cells up to 64N. The cells in the fruit fly larval salivary gland are huge; that's one reason their chromosomes are so easy to view. The cells that attach the human embryo's membrane sac to the wall of the uterus are trophoblast cells; they're huge too.

Eggs. Chicken eggs. Frog eggs. Most visible eggs.
And squids (cephalopods) have a very large neuron.
