WebJul 1, 2024 · Guard cells surround tiny pores called stomata, opening and closing them to allow for gas exchange required for photosynthesis. Chloroplasts and other plastids develop from cells called proplastids. Proplastids are immature, undifferentiated cells that develop into different types of plastids. Vacuoles are large intracellular storage organelles in plants cells. In addition to the ion channels in the plasma membrane, vacuolar ion channels have important functions in regulation of stomatal opening and closure because vacuoles can occupy up to 90% of guard cell’s volume. Therefore, a majority of ions are released from vacuoles when stomata are closed. Vascuolar K (VK) channels and fast vacuolar channels can mediate K release from vacuoles. Vacuolar K (VK) channels ar…
