Question

Which of the following statements are true for eukaryotic cells? (i) They do not have a nuclear membrane. (ii) They have a well organised nucleus. (iii) They have a nuclear membrane. (iv) Blue green algae are eukaryotic cells. ​

Answer 1

Answer: The eukaryotic cells are the advance cells that have a well-defined nucleus that is surrounded by a double-layered nuclear membrane. Within the nuclear membrane, the genetic material is present on the chromosomes. The genetic material is double-stranded DNA that is bound with positively charged histone proteins. The nucleus also has its own nucleoplasm that serves as the base for the nuclear activities like DNA replication and RNA formation.

Blue-green algae belong to the kingdom Monera because they are prokaryotic organisms. They do not have a well-organised nucleus.

Hence, the correct is '(ii) and (iii)'
