Open and close stomata with our engaging model!
Stomata (stoma singular) are tiny pores in the undersides of leaves that allow gas exchange to take place for photosynthesis. Show your students how they open and close with our dynamic model.
Buy once, print forever!
First, students make their model of a leaf epidermis with a stoma. They then use the model to look at how these guard cells control the opening and closing of the pore to reduce water loss by transpiration.
The model covers: epidermal cells, stomata and guard cells.
