No, personally I have never conducted experiments on animals; my focus has always been on agricultural crops.

Good Question.
Yes. We routinely use frogs oocytes to study plant transport proteins. To understand the function of plant proteins involved in nitrogen uptake (my research program), we express individual plant genes in the frog oocytes which after a few days become active proteins we can measure. This work is really important as it allows us to test how these plant proteins work and then test for improvements in their activity.
We have a special licence to house female African Clawed Frogs (Xenopus laevis) in Australia. We keep our frogs alive (many are 10-15 years old now) and sample each frogs oocytes once a year.

Sort of. I have been involved in trials to test pesticides that target aphids, moths, mites and snails who all love to munch on farmers’ vegetables. Insects can do a lot of damage in crops so it’s important to have pesticides that will keep them under control.

I use animals for my research frequently. The work I do involves looking at the behaviours of animals to measure how they are feeling, and so doesn’t harm or disturb them.
As scientists, whenever we use animals in research it has to be approved by an independent committee that makes sure the animals aren’t being unnecessarily harmed or disturbed during the research, and that an appropriate number of animals are being used for the experiment. This is called an Animal Ethics Committee.

No, but I have done lots of experiments on plants, including hooking them up to sensors and listening to the sounds they make! The water in xylem vessels can develop a bubble when under stress and cavitate. This releases the tension and makes a sound like fingers clicking. It can be heard a microphone connected to the plant.
