|
Plant cells have an envelope surrounding the nucleus. Animal cells do not.
|
|
|
Animal cells contain mitochondria. Plant cells do not.
|
|
|
Animal cells contain chloroplasts. Plant cells do not
|
|
|
Plant cells are surrounded by a cell wall. Animal cells are not.
|
Detailed explanation-1: -This option is correct, as only the plant cells have cell wall surrounding the plasma membrane and animal cells do not have cell wall. Hence the correct answer for this question is option d.
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: -A plant cell contains a cell wall, cell membrane, nucleus, plastid, central vacuole, Golgi apparatus, ribosome, mitochondria, lysosome, etc. An animal cell does not have a cell wall and plastids. Thus, the correct answer is option C.
Detailed explanation-4: -Answer and Explanation: The statement that is incorrect is a) Only animal cells have mitochondria. Plant cells have mitochondria as well. The other three statements are true: only plant cells have cell walls, both animal and plant cells have cytoplasm, and only plant cells have chloroplasts.
