The vacuole in a plant cell:

  1. A
    Lacks a membrane and contains water and excretory substances.
  2. B
    Is membrane-bound and contains storage proteins and lipids.
  3. C
    Is membrane-bound and contains water and excretory substances.
  4. D
    Lacks a membrane and contains air.

Solution & Step-by-step Explanation

In plant cells:The vacuole is a large, central organelle.It is bound by a single unit membrane called the tonoplast.It contains cell sap, which consists of water, dissolved salts, sugars, and often excretory waste products or pigments (like anthocyanins).Its primary function is maintaining turgor pressure and storing waste.
