The StomaToy video shows how plants and stomatal pores on leaves are important to us.
Start by watching the StomaToy video first, then go onto the leaf cube and activity book.
The StomaToy video features the electronic interactive StomaToy that demonstrates defence signalling in plants using lights.
Stomata are pores that open and close to protect against leaf drying while enabling CO2 entry into the leaf for photosynthesis. Closure of the Stomatal pore is the first line of defence against microbial pathogen infection. This gas exchange drives photosynthesis and helps plants to grow. Plants constantly face the conundrum of choosing growth vs immunity. Stomatal biologists study how plants control stomatal movements in response to environmental changes using cell biology, mathematical modelling and plant physiology analysis.
