Description

VACUOLES A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance. Sometimes a single vacuole can take up most of the interior space of the plant cell. Vacuoles are fluid filled organelles surrounded by a membrane. Animal cells have small sized vacuoles whereas plant cells have large vacuoles. ... It acts as storage sacs of cell and stores food, water, sugar, minerals and waste products of the cell.

Function       

Isolating materials that might be harmful or a threat to the cell. Containing waste products. Containing water in plant cells. Maintaining internal hydrostatic pressure or turgor within the cell. Maintaining an acidic internal pH. Containing small molecules. Exporting unwanted substances from the cell.

Vacuoles are of 4 types: Food vacuole, Sap vacuole, Gas vacuole, Contractile vacuole. What color is a vacuole? Plant Cell Coloring Cell Membrane (orange) Nucleoplasm (yellow) Mitochondria (red) Vacuole (light blue) Chromosomes (gray) Cell Wall (dark green) Nucleolus (brown) Chloroplasts (light green) Smooth Endoplasmic Reticulum (pink) Rough Endoplasmic Reticulum (pink) Plant vacuoles INTRODUCTION 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 homeostasis. They are involved in cellular responses to environmental and biotic factors that provoke stress. Plant cell vacuoles were discovered with the early microscope and, as indicated in the etymology of the word, originally defined as a cell space empty of cytoplasmic matter. Technical progress has variously altered the operating definition of the plant vacuole over time. Today, definitions continue to be colored by the tools and concepts brought to bear in any given study. Indeed, the combination of microscopy, biochemistry, genetics, and molecular biology is fundamental to research into the plant vacuole. In this review, vacuoles are provisionally defined as the intracellular compartments that arise as a terminal product of the secretory pathway in plant cells. They are ontogenetically and functionally linked with other components of the vacuolar apparatus (i.e., vacuoles and those membranous bodies that are either committed to becoming vacuolar or have immediately completed a

vacuolar function). Experimental evidence suggests that material within the vacuolar system in plants derives confluently from both an intracellular biosynthetic pathway and a coordinated endocytotic pathway.

Animal Vacuoles Who discovered vacuoles in animal cells? Antonie van Leeuwenhoek In 1676, Antonie van Leeuwenhoek, inventor of the microscope, discovered vacuoles. He examined bacteria (his first subjects) under microscope and he was the discoverer not just of vacuoles but of many other cellular structures. A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance. Sometimes a single vacuole can take up most of the interior space of the plant cell.

Vacuoles are storage sacs found in most eukaryotic cells. They are membranebound and filled with a fluid containing organic or inorganic molecules. Plant cells have one large vacuole, while animal cells tend to have several smaller ones. Animal cells do not have a central vacuole as seen in plant cells. However, animal cells, especially fat cells, have membrane enclosed vacuoles for storage, waste, etc. The vacuole is a type of organelle present in eukaryotic cells. It is a sac surrounded by a single membrane called a tonoplast. Vacuoles serve many functions, depending on the needs of the cell. In animal cells, they are small and typically transport materials into and out of the cell....
