In the classification of eukaryotes, protsists were once placed in a single kingdom. Briefly evaluate whether this classification system is accurate.

Why might it be difficult to classify some slime molds as unicellular or multicellular?

I know the first one is innacurate, but why exactly? 2nd one, I'm just confused. A clear, simple sentence (or two) explaining these two questions would be great cause I'm confused:p

this was NOT accurate, seeing as protists have many characteristics that were similar to animal

Slime molds can generally be divided into two main groups. A plasmodial slime mold involves numerous individual cells attached to each other, forming one large membrane. This "supercell" (a syncytium) is essentially a bag of cytoplasm containing thousands of individual nuclei. See https://en.wikipedia.org/wiki/Heterokaryon

thx bobpursley.

You and the whole Jiskha team, including teachers and students alike, are all a big help! Thanks again!

The classification system that placed all protists in a single kingdom is not accurate because protists are a highly diverse group of eukaryotic organisms with various characteristics and evolutionary histories. This single kingdom classification oversimplified the complexity and diversity within this group.

Regarding the classification of slime molds as either unicellular or multicellular, it can be difficult because of their unique life cycles. Some slime molds exist as independent single-celled organisms during certain stages of their life cycle, while in other stages they aggregate to form multicellular structures that resemble fungi. This dual nature of slime molds makes it challenging to classify them strictly as either unicellular or multicellular.

Thanks bob, but I think I'm gonna repost the 2nd question... I'm still struggling with it:/
