  4. Discovery Contractile vacuoles (stars) were first observed by Spallanzani (1776) in protozoa, although mistaken for respiratory organs. Dujardin (1841) named these stars as vacuoles.In 1842, Schleiden applied the term for plant cells, to distinguish the structure with cell sap from the rest of the protoplasm..

Vacuole, in biology, a space within a cell that is empty of cytoplasm, lined with a membrane, and filled with fluid. Especially in protozoa (single-celled eukaryotic organisms), vacuoles are essential cytoplasmic organs (organelles), performing functions such as storage, ingestion, digestion, excretion, and expulsion of excess water A vacuole is a cell organelle found in a number of different cell types. Vacuoles are fluid-filled, enclosed structures that are separated from the cytoplasm by a single membrane. They are found mostly in plant cells and fungi. However, some protists, animal cells, and bacteria also contain vacuoles A vacuole is a membrane bound structure found in the cytoplasmic matrix of a cell. The membrane surrounding the vacuole is known as tonoplast. The components of the vacuole, known as the cell sap, differ from that of the surrounding cytoplasm. The membranes are composed of phospholipids 縁取り空胞を伴う遠位型ミオパチー (Distal myopathy with rimmed vacuoles [DMRV])は、1981年にNonakaらにより報告されたことから 、埜中ミオパチー (Nonaka myopathy)とも呼ばれる。

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 A vacuole is an organelle in cells which functions to hold various solutions or materials. This includes solutions that have been created and are being stored or excreted, and those that have been phagocytized, or engulfed, by the cell vacuoleとは。意味や和訳。[名]《生物》空胞,液胞;(生体組織内の)小腔しょうこう - 80万項目以上収録、例文・コロケーションが豊富な無料英和和英辞典 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 A vacuole is a membrane-bound organelle (like a bubble) that is present in all plant cells. Some animal and fungal cells also have vacuoles, but they are much smaller. Most mature plant cells have one large central vacuole that can occupy as much as 80% of the cell volume, making the vacuole the most prominent organelle in plant cells

On the one hand, most vegetative tissues develop lytic vacuoles that have a role in degradation. On the other hand, seed cells have two types of storage vacuoles: protein storage vacuoles (PSVs) in endosperm and embryonic cells and metabolite storage vacuoles in seed coats Vacuoles are found in the cells of plants, protists, and some primitive animals. In mature plant cells, there is usually one large vacuole which occupies a large part of the cell's volume and is filled with a liquid called cell sap. The cell sap stores food reserves, pigments, defensive toxins, and waste products to be expelled or broken down Almost all plant cells have large vacuoles that contain both hydrolytic enzymes and a variety of defense proteins.

Large vacuoles are also found in three genera of filamentous sulfur bacteria, the Thioploca, Beggiatoa, and Thiomargarita. However, the function and significance of vacuoles vary greatly according to the type of cell having much greater prominence in the cells of plants, fungi, and certain protists than those of animals and bacteria Vacuoles are a kind of storage bubbles present in the plant cells. Such plants that have vacuoles may not appear healthy and need a lot of water. Vacuoles can even store food products or a variety of different nutrient Vacuoles can be large organelles occupying between 30% and 90% of a cell by volume. Vacuoles appear to have three main functions, they: contribute to the rigidity of the plant using water to develop hydrostatic pressur Like lysosomes, peroxisomes are single membrane-bound vesicles that contain digestive enzymes. The chief function of these basic organelles is to enzymatically oxidize fatty acids and to subsequently catalyze the breakdown of H 2 O 2, a by-product of fatty acid degradation Vacuoles in animal cells, however, tend to be much smaller, and are more commonly used to temporarily store materials or to transport substances. The central vacuole in plant cells (see Figure 1) is enclosed by a membrane termed the tonoplast , an important and highly integrated component of the plant internal membrane network ( endomembrane ) system

This conclusion is based on the following five seminal observations: (1) almost all autophagic vacuoles of alternative autophagy were localized near the Golgi apparatus, (2) Golgi ministack formation preceded autophagosome generation, (3) some isolation membranes extended from the Golgi membranes, (4) trans-Golgi proteins were observed on autophagosomes and autolysosomes, and (5) the depletion. Vacuoles are lost in some cells in a confined area, leaving an increased amount of cytoplasm (dark green). Vacuole loss renders the notochord more deformable, causing asymmetric centra growth and spine kinking.
