Which plant cell organelle helps maintain the shape of the cell by helping to maintain turgor pressure?
dlinn [17]

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 shape of a protein is primarily determined by
bulgar [2K]


The best answer is A.

The shape of a protein is determined by its primary structure. The primary structure is the sequence of amino acids  in each polypeptide chain which make up a protein.

The sequence of amino acids is basically a list of amino acids that are linked to each other to form a chain which is known as a polypeptide chain.

The structure of the finished protein will depend largely on the first  (primary) chain of amino acids to be produced to make up that protein.
