Vacuoles
1. What is the Main Function of Vacuoles?
Answer:
The primary function of vacuoles is to store various substances, including water, ions, sugars, pigments, toxins, and waste products.
2. What are Vacuoles Made of?
Answer:
Vacuoles consist of a membrane (tonoplast) made of lipids and proteins, surrounding a fluid called cell sap, which contains water, ions, sugars, pigments, and other dissolved substances.
3. What is the Role of Vacuoles in Intracellular Digestion?
Answer:
Vacuoles are involved in intracellular digestion by absorbing dietary substances through endocytosis and excreting waste through exocytosis. Lysosomes attached to vacuoles contain digestive enzymes.
4. Where is the Vacuole Found?
Answer:
Vacuoles are found in the center of a cell. They vary in size and shape depending on the type of cell. Plant cell vacuoles are very large in size and store large amounts of water. Vacuole also helps the plant maintain its firm shape.
5. What are the Different types of Vacuoles in the Cell Membrane?
Answer:
They are classified into three groups depending on their contents and functionality.
- Sap vacuoles
- Food vacuoles
- Contractile vacuoles
Vacuoles
Vacuole is a cellular organelle that is found in plants, fungi, and some types of protists. In plant cells, it helps in maintaining turgor pressure, contributing to the plant’s structural support and rigidity. Vacuoles contain various substances like ions, water, and waste products. It also contributes to essential cellular functions like regulating cell volume, takes part in digestion, and helps in the breakdown of cellular components.
