|
Animal cells have mitochondria and plant cells do not.
|
|
|
Plant cells have lysosomes and animal cells do not.
|
|
|
Only plant cells have centrioles around their nucleus.
|
|
|
Only plant cells have large central vacuoles and cell walls.
|
Detailed explanation-1: -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-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: -Three differences between a plant cell and an animal cell are: Animal cell lack cell wall, unlike a plant cell which has a cellulosic cell wall. Animal cell lack chloroplast, whereas plant cell has chloroplast. Animal cell has centrioles, centrosome, and lysosome but plant cell lack them.
Detailed explanation-4: -In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance. Sometimes a single vacuole can take up most of the interior space of the plant cell.
Detailed explanation-5: -Plant cells are known to have bigger vacuoles than that of animal cells as they need to store food and water. This is because the plant don’t possess the ability to move freely like that of animals. Thus, they possess large vacuoles as a reservoir in unfavorable conditions.
