Mature Plant Cells Generally Contain A Small Central Vacuole (2023)

FAQs

Do plant cells have a small central vacuole? ›

Many plant cells have a large, single central vacuole that typically takes up most of the room in the cell (80 percent or more). Vacuoles in animal cells, however, tend to be much smaller, and are more commonly used to temporarily store materials or to transport substances.

Plant cells have a cell wall and a large central vacuole. In the mature plant, the central vacuole may occupy 50-90% of the cell interior. It stores amino acids, sugars, water ions, and wastes. The cytoplasm is forced into a very narrow zone between the central vacuole and the plasma membrane.

The plant has the largest vacuole than animal cells because in plant cells the larger central vacuole performs two functions, one is to store water and the other is to help the plant remain upright.

The Central Vacuole

Most mature plant cells have a central vacuole that occupies more than 30% of the cell's volume. The central vacuole can occupy as much as 90% of the volume of certain cells. The central vacuole is surrounded by a membrane called the tonoplast. The central vacuole has many functions.

The vacuole is an important part of many cells. Mature cells of all terrestrial plants, most fungi, and algae (except prokaryotic cells) have vacuoles. However, there are no vacuoles in animal cells and in the immature plant cells, as well as some highly mature plant cells (such as stone cells).

Plant cells are known to have bigger vacuoles than that of animal cells as they need to store food and water. This is because the plant don't possess the ability to move freely like that of animals. Thus, they possess large vacuoles as a reservoir in unfavorable conditions.

So, the correct answer is 'Protoplasm, cell wall, and vacuole'.

Within plant cells, there is a large vacuole called the central vacuole. A cell's vacuole is a spherical filled with liquid and molecules. In a plant cell, the central vacuole stores water and regulates turgor pressure.

The lysosomes are the animal cell's “garbage disposal”, while in plant cells the same function takes place in vacuoles. Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, which are not found within animal cells.

A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane.

Are large and small vacuoles in plant cells? ›

Many plant cells possess a single large central vacuole, while other plant cells have several smaller vacuoles. Animal vacuoles, by contrast, represent small lysosome-type organelles that are involved in the endocytosis of waste products.

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.

So, the correct answer is 'Mature plant cells'.

Animal cells do not have a central vacuole like plant cells. Animal cells may have multiple small vacuoles, but they are not as prominent or central as the vacuole in plant cells. Vacuoles in animal cells serve different functions, such as storing waste materials or regulating cell volume.

The central vacuole can occupy up to 90% of the cellular volume and, differently from intracellular organelles from animal cells such as lysosomes or endosomes, it is easy to isolate. Because of its large dimension (up to 40 μm diameter) it can be successfully studied using the classical patch-clamp technique.
