Which statement is true of viroids?
they are single-stranded rna particles.
they reproduce only outside of the cell.
they produce proteins.
they affect both plants and animals.

Viroids are single-stranded RNA particles

Explanation:

Viroids are acellular particles of small circular single-stranded RNA, doesn't have its genomic material in a capsule. This RNA don’t codify proteins, they only replicate autonomously. Viroids can’t reproduce of their own, they must need host cells for its reproduction. Most of them are infectious particles causing damage to cultivated plants making an important impact on agriculture.

uh two lol

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.
