WebKey points: Mitochondria are the "powerhouses" of the cell, breaking down fuel molecules and capturing energy in cellular respiration. Chloroplasts are found in plants and algae. They're responsible for capturing light energy to make sugars in photosynthesis. Mitochondria and chloroplasts likely began as bacteria that were engulfed by larger ... 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…
