What is a key organelle needed in a animal cell?
Cell membrane, cytoplasm, and/or the nucleus.
Who was it that discovered animal cells?

This cell has dendrites to connect to other neurons. A long axon carries the impulse along the cell to the axon terminals. There are lots of mitochondria here to release energy for the production of chemical messeges for use in the synapse.
A neuron cell.
What membrane bound organelles does a eukaryotic cell have but not a prokaryotic cell?
All organelles.
After attaching to a host cell, this is the next step a virus takes to reproduce.
It injects its genetic material or entering the host cell.
