How would you describe a vacuole?
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.
What is the function of a plant vacuole?
The vacuole plays an important role in the homeostasis of the plant cell. It is involved in the control of cell volume and cell turgor; the regulation of cytoplasmic ions and pH; the storage of amino acids, sugars, and CO2; and the sequestration of toxic ions and xenobiotics.
What is a sentence for vacuole?
1, Plant cells contain liquid in spaces called vacuoles. 2, The contractile vacuole expands and eventually discharges the water it contains to the exterior through the cell membrane. 3, A vacuole is surrounded by a thin layer of cytoplasm which acts as a semi-permeable membrane.
What are SAP vacuoles describe their functions?
The cell sap vacuole are large vacuoles found in both animal and plant cell. Their role is to store materials and provide mechanical support to the cell. It also maintains Turgor pressure of the cell. The fluid present inside the vacuole is known as cell sap.
What is a another word for vacuole?
In this page you can discover 10 synonyms, antonyms, idiomatic expressions, and related words for vacuole, like: organelle, syncytium, cell, cytoplasm, vesicle, lysosome, nucleolus, mitochondrion, enterocytes and large-intestine.
How do you use Centriole in a sentence?
centrioles in a sentence
- The two centrioles in the centrosome are tied to one another.
- The sperm contributes a pronucleus and a centriole to the egg.
- First, the connection between the two parental centrioles is destroyed.
- The mother centriole has radiating appendages at the proximal end.
What is the function of a permanent vacuole?
A permanent vacuole is part of a plant cell that stores cell sap.
What is the structure of the vacuole?
Structure of Vacuole. 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.
Why do vacuoles have different properties in plant cells?
In each organism, different genetics cause different proteins to be embedded in the membrane of the vacuole, which allow different molecules through, and gives the vacuoles different properties. Most plant cells have evolved to use vacuoles as water storage organelles, which provide a variety of functions to the cell.
What is the solution that fills a vacuole?
The solution that fills a vacuole is known as the cell sap. The vacuole is also filled with protons from the cytosol that helps in maintaining an acidic environment within the cell. A large number of lipids are also stored within the vacuoles. The vacuoles are completely filled with water and exert force on the cell wall.
