which descriptions apply to prokaryotic cells? choose three correct answers.
are usually single - celled

have dna located in cytoplasm

contain a nucleus

do not contain membrane - bound organelles

Explanation:

1. Prokaryotic cells are usually single - celled organisms (e.g., bacteria).
2. In prokaryotic cells, DNA is located in the cytoplasm (they lack a nucleus to enclose DNA).
3. Prokaryotic cells do not contain membrane - bound organelles (unlike eukaryotic cells which have organelles like mitochondria, endoplasmic reticulum etc. enclosed in membranes). The option "contain a nucleus" is incorrect as prokaryotes lack a nucleus.

Answer:

• are usually single - celled
• have DNA located in cytoplasm
• do not contain membrane - bound organelles
