What is the main function of a vacuole in a cell?
What is the main function of a vacuole in a cell?
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 are the cellular organelles and their functions?
What’s found inside a cell
| Organelle | Function |
|---|---|
| Nucleus | DNA Storage |
| Mitochondrion | Energy production |
| Smooth Endoplasmic Reticulum (SER) | Lipid production; Detoxification |
| Rough Endoplasmic Reticulum (RER) | Protein production; in particular for export out of the cell |
What are the three parts of the cell theory?
These findings led to the formation of the modern cell theory, which has three main additions: first, that DNA is passed between cells during cell division; second, that the cells of all organisms within a similar species are mostly the same, both structurally and chemically; and finally, that energy flow occurs within …
How does the vacuole maintain cell turgidity?
-Turgidity: Vacuoles regulate the turgidity by regulating the amount of water present inside the cell. the cell has excessive water: vacuole usually absorbs the water and then diffuses it out of the cell. -cell lacks water: water from the vacuole tends to revert into the cell thereby maintaining turgidity.
What does the cytoplasm do?
The cytoplasm is the gel-like fluid inside the cell. It is the medium for chemical reaction. It provides a platform upon which other organelles can operate within the cell. All of the functions for cell expansion, growth and replication are carried out in the cytoplasm of a cell.
What are the 7 main organelles?

- Cell Membrane. The thin, flexible outer covering of a cell and controls what enters and leaves the cell.
- Cytoplasm. The gel-like fluid inside of a cell made mostly of water and it holds other organelles in place.
- Nucleus.
- Vacuole.
- Chloroplasts.
- Mitochondria.
- Cell Wall.
What are the 5 most important organelles in a cell?
5 most important Organelles in a Cell
- Nucleus. The Nucleus is the central and most important part of an object, movement or group, forming the basis for its activity and growth (like the brain of a cell)
- Mitochondrians.
- Flagella.
- Golgi Apparatus.
- Cell Membrane.
Who are the 5 scientists who contributed to the cell theory?
Although cells were first observed in the 1660s by Robert Hooke, cell theory was not well accepted for another 200 years. The work of scientists such as Schleiden, Schwann, Remak, and Virchow contributed to its acceptance.
What are the 4 parts of cell theory?
Terms in this set (4)
- FIRST PART. CELLS CONTAIN DNA THAT IS PASSED CELL TO CELL DURING CELL DIVISION.
- SECOND PART. CELLS ARE SIMILAR IN CHEMICAL COMPOSITION AND REACTIONS THAT MAINTAIN HOMEOSTASIS.
- THIRD PART. ALL BASIC CHEMICAL AND PHYSIOLOGICAL FUNCTIONS ARE CARRIED OUT INSIDE THE CELL.
- FOURTH PART.
