Eukaryotic Cell Labeled Diagram Game Quiz - A eukaryotic cell contains a membrane-bound nucleus and several organelles such as mitochrondia and ribosomes. Plants, animals, fungi and protozoa are composed of eukaryotic cells, and are called eukaryotes.
While prokaryotes and eukaryotes both possess parts like the cellular membrane, ribosomes and the cytoplasm, eukaryotic cells are tens to hundreds of times larger than prokaryotic cells.
The nucleus containing the DNA of a eukaryotic cell is surrounded by a double-membrane structure called the nuclear membrane. The rest of the cell’s organelles are similarly enclosed in plasma membranes.
Examples of a eukaryotic cell’s organelles include the mitochrondia, which generate the cell’s energy, ATP; endoplasmic reticulum, which produce lipids and modify proteins; lysosomes, which digest various substances; and Golgi apparatuses, which package and transport substances throughout the cell.
Eukaryotic cells can also differ in structure. For instance, plant cells possess a rigid cell wall, a light-capturing organelle called the chloroplast, and substance-storing vacuoles that are absent in animal cells.
Some cells can be specialized for various functions; red blood cells in mammals do not contain DNA, a nucleus, or organelles. This allows the insides of a red blood cell to carry much more oxygen within hemoglobin molecules. Furthermore, as red blood cells are unable to perform protein synthesis, viruses which enter the cell cannot create more of themselves and simply die.
This eukaryotic cell labeled diagram is designed to enrich your knowledge of eukaryotic cellular structure, function and activities and assist in distinguishing eukaryotic cells from prokaryotic cells.
