which of the following would you expect to find in the cytoplasm of archaeal cells?
□ ribosomes
□ nucleus
□ nucleoid
□ endoplasmic reticulum
□ plasmids

Explanation:

1. Archaea are prokaryotes, so they lack a nucleus (a membrane - bound organelle) and endoplasmic reticulum (a membrane - bound organelle of eukaryotes).
2. Ribosomes are present in the cytoplasm of archaea as they are needed for protein synthesis.
3. The nucleoid, which is the region containing the circular DNA, is present in the cytoplasm of archaea.
4. Some archaea can have plasmids (small, circular, extra - chromosomal DNA) in their cytoplasm.

Answer:

A. ribosomes, C. nucleoid, E. plasmids
