Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Eukaryotes are complex cells with a nucleus and other membrane bound organelles.
A
True
B
False
Explanation: 

Detailed explanation-1: -Eukaryotic cells are larger than prokaryotic cells and have a “true” nucleus, membrane-bound organelles, and rod-shaped chromosomes. The nucleus houses the cell’s DNA and directs the synthesis of proteins and ribosomes.

Detailed explanation-2: -A eukaryotic cell is a cell that has a membrane-bound nucleus and other membrane-bound compartments or sacs, called organelles, which have specialized functions. The word eukaryotic means “true kernel” or “true nucleus, ” alluding to the presence of the membrane-bound nucleus in these cells.

Detailed explanation-3: -Eukaryotic cells like plant cell and animal cells contain a well defined nucleus and have all the membrane bound organelles. E.g., Golgi bodies, mitochondria, endoplasmic reticulum, etc. Whereas prokaryotic cells like bacterial cells do not contain membrane bound cell organelles.

Detailed explanation-4: -Bacteria lack the membrane-bound nuclei of eukaryotes; their DNA forms a tangle known as a nucleoid, but there is no membrane around the nucleoid, and the DNA is not bound to proteins as it is in eukaryotes.

Detailed explanation-5: -Eukaryotic cells are the most complex cell type that have a membrane-enclosed nucleus and organelles that carry out the functions of the cell. Examples of cells that are eukaryotic include plant and animal cells.
