Which one of the following characteristics must a cell have in order to be classified as a eukaryotic cell?
A
Two or more circular chromosomes
B
No membrane bound organelles
C
A cytoskeleton attached to the cell membrane
D
A cell wall made of cellulose
Explanation: 

Detailed explanation-1: -The features of eukaryotic cells are as follows: Eukaryotic cells have the nucleus enclosed within the nuclear membrane. The cell has mitochondria. Flagella and cilia are the locomotory organs in a eukaryotic cell.

Detailed explanation-2: -Eukaryotic cells have a true nucleus and membrane-bound organelles like mitochondria, Golgi complex, etc. The cell organelles and nucleus is embedded in the cytoplasm. The cell is covered with the plasma membrane. They have rod-shaped chromosomes, inside the nucleus which is covered by a nuclear membrane.

Detailed explanation-3: -Eukaryotic Cell Structure However, unlike prokaryotic cells, eukaryotic cells have: a membrane-bound nucleus. numerous membrane-bound organelles (including the endoplasmic reticulum, Golgi apparatus, chloroplasts, and mitochondria) several rod-shaped chromosomes.

Detailed explanation-4: -Eukaryotic cells are cells containing membrane-bound organelles and are the basis for both unicellular and multicellular organisms. In contrast, prokaryotic cells do not have any membrane-bound organelles and are always part of unicellular organisms.

Detailed explanation-5: -Animal cells, plant cells, fungi, and protists are eukaryotes (eu– = true).
