CELL STRUCTURE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
You are told that the cells on a microscope slide are plant, animal, or bacterial. You look at them through a microscope and see cell walls and membrane-bound organelles. How should these cells be classified?
A
plant cells
B
animal cells
C
They could be plant cells or bacterial cells.
D
They could be plant cells, animal cells or bacterial cells.
Explanation: 

Detailed explanation-1: -The cells that have a cell wall and membrane-bound organelles are the plant cell. So we can conclude that the cells on the slide are plant cells. Q.

Detailed explanation-2: -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.

Detailed explanation-3: -Animal cells have centrioles, centrosomes (discussed under the cytoskeleton), 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.

Detailed explanation-4: -The cell wall is present in plant cells and absent in animal cells.

Detailed explanation-5: -The cell wall, nucleus, vacuoles, mitochondria, endoplasmic reticulum, Golgi apparatus, and ribosomes are easily visible in this transmission electron micrograph.
