Both plant and animal cells have the following organelles: mitochondrion, golgi apparatus, ribosomes, nucleus, cell membrane, rough and smooth ER and cytoplasm.
In animal cells, cell wall is absent unlike in plant cells. The plant cell has a regular shape whilst the animal cell has an irregular shape. Animal cells do not have chloroplasts whilst the plant cells do. In animal cells, small or no vacuole is present whilst the plant cells have a large vacuole
1. It does this to protect host's cells and keep the virus in the same spot so white blood cells can kill them.
