Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Eukaryotic cells differ from prokaryotic cells. This is because all eukaryotic cells have:I. 80S ribosomesII. a cellulose cell wallIII. mitochondria
A
I and II only
B
I and III only
C
II and III only
D
I, II and III
Explanation: 

Detailed explanation-1: -The primary difference between prokaryotic and eukaryotic cells is that a nucleus and other membrane-bound organelles are only present in eukaryotic cells.

Detailed explanation-2: -Eukaryotic cells have chloroplasts and mitochondria as organelles and people organelles even have ribosomes 70S. Therefore, eukaryotic cells have differing types of ribosomes (70S and 80S), whereas prokaryotic cells only have 70S ribosomes.

Detailed explanation-3: -Life, as we know it, is classified into prokaryotes and eukaryotes, each with its own special ribosome structure. Eukaryotic ribosomes are called 80S ribosomes while prokaryotes such as bacteria have a smaller version called 70S ribosomes.

Detailed explanation-4: -In prokaryotic cells, the cell wall is present and it is very complex in nature. Eukaryotic cells have cell walls very rarely, if present they have simple chemical nature. True nucleus is present. In prokaryotic cells, cytoplasm is present, but it is lacking in most cell organelles.
