When unsure if they need water, just stick your finger into the soil near your plant. If it's dry, water. If still unsure, dig down a couple of inches and grab a golf ball sized amount of soil...squeeze it...if it crumbles it's too dry, if it sticks together, it's moist enough.

From what I understand, it is done much like tissue culture. They would take a cell from an animal and put it on a growing medium(agar for plants)..don't know what it is for animals..then by adding hormones it would replicate over and over until it is a large enough for whatever their purpose...
