Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of these is NOT a unique structure to plant cells?
A
cell wall
B
central vacuole
C
chloroplas
D
nucleus
Explanation: 

Detailed explanation-1: -Plant cells do not have lysosomes or centrosomes.

Detailed explanation-2: -Centrosomes and lysosomes are found in animal cells, but do not exist within plant cells. The lysosomes are the animal cell’s “garbage disposal”, while in plant cells the same function takes place in vacuoles.

Detailed explanation-3: -Plant cells are eukaryotic, which means that they contain a distinct nucleus. Plant cells have three unique structures which set them apart from other eukaryotes, such as animal cells: the cell wall, plastids, and vacuoles.

Detailed explanation-4: -Plant cells have certain distinguishing features, including chloroplasts, cell walls, and intracellular vacuoles. Photosynthesis takes place in chloroplasts; cell walls allow plants to have strong, upright structures; and vacuoles help regulate how cells handle water and storage of other molecules.

Detailed explanation-5: -So, the correct answer is ‘Centriole’.
