Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Carrie observes an electron micrograph of a cell during biology lab. The cell has a flagellum, ribosomes, cell wall, and no apparent nucleus. Which of the following is likely true of the cell that Carrie is observing?
A
The cell also contains mitochondria.
B
The presence of the organelles proves that the cell is eukaryotic.
C
The cell is a plant because of the cell wall.
D
The cell is prokaryotic.
Explanation: 

Detailed explanation-1: -Carrie observes an electron micrograph of a cell during biology lab. The cell has a flagellum, ribosomes, cell wall, and no apparent nucleus. Which of the following is likely true of the cell that Carrie is observing? The cell also contains mitochondria.

Detailed explanation-2: -Since the cell has a large central vacuole, it must be a plant cell.

Detailed explanation-3: -List ten structures you could find in an electron micrograph of an animal cell which would be absent from the cell of a bacterium. Golgi bodies, smooth ER, rough ER, nucleus, mitochondria, centrioles, lysosomes, nucleolus, cytoskeleton, and 80s ribosomes.

Detailed explanation-4: -Animal cells each have a centrosome and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, whereas animal cells do not.

Detailed explanation-5: -Animal cells have centrosomes (or a pair of centrioles), and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts, plasmodesmata, and plastids used for storage, and a large central vacuole, whereas animal cells do not.
