Spotlight on… Viruses! With Izzy the Inspector
Viruses are tiny (even smaller than bacteria) and they can’t be seen with an ordinary microscope! They have a very simple structure and can’t grow outside living plants. Symptoms of viruses on plants can look very different depending on the virus and the particular plant they are found on. The symptoms can appear on all parts of the plant.
Izzy goes to see her Aunt Anne for lunch. She shows Izzy the new cucumber plants she bought off the internet - they were a bargain! However, when Izzy looks at the plants in Aunt Anne’s greenhouse she thinks they might have a virus as some of the leaves look unhealthy.
