Stomata are surrounded by guard cells that control pore size; they open when turgid and close when flaccid.
Qual é a estrutura dos estômatos? Eles são cercados por células guarda que mudam de forma para controlar o tamanho do poro. Quando estão túrgidas, os estômatos estão abertos e quando estão flácidas, os estômatos estão fechados.
