Abstract Vacuoles are organelles in plant cells that play pivotal roles growth and developmental regulation. The main functions of vacuoles include maintaining cell acidity turgor pressure, regulating the storage transport substances, controlling localization key proteins through endocytic lysosomal-vacuolar pathways, responding to biotic abiotic stresses. Further, localized either tonoplast (v...

INTRODUCTION is attributable to the parietal distribution of the vacuoles within the cells of the particular strain of blue-green alga used in these experiments . Gas vacuoles are small, cylindrical, gas-filled vesicles which occur in certain procaryotic cells . They are found in numerous blue-green algae, many photosynthetic bacteria, some halophilic bacteria, and some planktonic freshwater ba...

The vacuoles of plant cells are multifunctional organelles that are central to cellular strategies of plant development. They share some of their basic properties with the vacuoles of algae and yeast and the lysosomes of animal cells. They are lytic compartments, function as reservoirs for ions and metabolites, including pigments, and are crucial to processes of detoxification and general cell ...
