Which of the following structure is present in animal cell but not in red blood cell.
A
Nucleus
B
Cell membrane
C
Cytoplasm
D
Cell wall
Explanation: 

Detailed explanation-1: -Animal cells have lysosomes and centrosomes.

Detailed explanation-2: -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-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: -Final answer: Centrioles and lysosomes are found only in animal cells and not in plant cells.

Detailed explanation-5: -The nucleus is an organelle found in most eukaryotic cells, the exception being red blood cells. In animal cells it is both the largest and stiffest organelle and is easily identifiable by light microscopy. The average mammalian nucleus has a diameter of  6µm and occupies about 10% of the total cell volume.
