So, you know how some flowers have boy parts and some flowers have girl parts? Well, in androdioecy, some plants have flowers that have both boy parts and girl parts, while other plants have flowers that only have boy parts.
Think of it like having a toy that can morph into different things - sometimes it's a car with both a steering wheel and gas pedals, and other times it's just a race car with only gas pedals.
In androdioecy, the plants that only have boy parts can make pollen, but they can't make seeds. On the other hand, the plants with flowers that have both boy and girl parts can make both pollen and seeds.
It's like one plant is in charge of making the pollen, and the other plant is in charge of making the seeds. They work together to make sure that new plants can grow.
And that's basically what androdioecy is - it's when some plants have flowers with both boy and girl parts, while others only have boy parts. It's a way for plants to make sure they can keep on growing and making new plants.
