Answer: Vacuole
Explanation:
The vacuole occupies on average 50% of the cell volume, oscillating between 5 and 95%. It is a fluid-filled, membrane-wrapped gallbladder. The vacuoles perform numerous functions because, in addition to accumulating nutrients, metabolites, and catabolites, they serve as deposits of specific substances such as proteins, opium, dairy and also various poisonous or unpleasant taste substances, which protect the plant against its predators.
Vacuoles are structures that participate in the maintenance of cell turgor, which pulls the cytoplasm against the cell wall as air tightens the air chamber against the tire. When water is lacking, the plant wilts due to decreased intracellular turgor.
The amoeba is a eukaryote whose bodies most often consist of a single cell.
The cells of amoebae, like those of other eukaryotes, possess certain characteristic features. For example:-
1. Their cytoplasm and cellular contents are enclosed within a cell membrane.
2. Their DNA is packaged into a central cellular compartment called the nucleus.
3. They contain specialized structures called organelles, which execute a range of cellular functions including energy production and protein transport.
