Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which cells contain a true nucleus?
A
prokaryotes
B
eukaryotes
C
carbohydrate
D
plant cells
Explanation: 

Detailed explanation-1: -Eukaryotes (meaning ‘true nuclei” where “karyote” is derived from the ancient Greek for “kernel") include fungi, protozoa, eukaryotic algae, and of course plants and animals including ourselves. Eukaryotic cells have a nucleus containing chromosomal DNA bounded by membranes.

Detailed explanation-2: -Eukaryotic cells have a true nucleus, which means the cell’s DNA is surrounded by a membrane. Therefore, the nucleus houses the cell’s DNA and directs the synthesis of proteins and ribosomes, the cellular organelles responsible for protein synthesis.

Detailed explanation-3: -Eukaryotic cells, on the other hand, have chromosomes that are enclosed in a true nucleus, and are therefore separated from the cytoplasm by the nuclear membrane. Eukaryotic cells also have a wide range of organelles that perform specialized functions.

Detailed explanation-4: -The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information.

Detailed explanation-5: -The nucleus is an important organelle in eukaryotic cells because it contains the genetic information of the cell or DNA. It is also the site of DNA replication, translation, and ribosome synthesis.
