Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Using a microscope in the science lab, Jill observed two unknown cells:Cell 1 and Cell 2. Cell 1 she identified as a plant cell and Cell 2 as an animal cell. Her teacher told her she identified the cells correctly. What did Jill most likely observe to correctly identify the cells?
A
Cell 2 had a cell membrane and Cell 1 did not.
B
Cell 1 had a cell wall and Cell 2 did not.
C
Cell 2 had a chloroplast and Cell 1 did not.
D
Cell 1 had a nucleus and Cell 2 did not.
Explanation: 

Detailed explanation-1: -The correct answer is: Option B. Cell 1 had a cell wall and Cell 2 did not. Plant cells are the eukaryotic cells, which consist of the cell organelles like mitochondria, nucleus, cytoplasm, chloroplasts, and Golgi apparatus.

Detailed explanation-2: -Plant cells will look green, due to round structures called chloroplasts, and will have a thick cell wall outside their cell membrane and be arranged in a grid. Both plant and animal cells have a nucleus which appears as a large dot in the center of the cell.

Detailed explanation-3: -Organelles that can be seen and observed under a light microscope include the nucleus, cytoplasm, cell membrane, chloroplasts, and cell wall. The chloroplasts and cell walls are only present in plant cells.

Detailed explanation-4: -Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane. This gives the plant cell its unique rectangular shape. Animal cells simply have a cell membrane, but no cell wall.
