Tonoplast is the covering of

  1. Cell wall

  2. Nucleus

  3. Mitochondria

  4. Vacuole


Correct Option: D
Explanation:

The plant cell usually has a single large centrally located vacuole. The tonoplast is a special term for the membrane found around plant cell vacuole. Thus, the correct answer is option D.

  1. Chloroplast

  2. Cytoplasm

  3. Mitochondria

  4. Vacuole


Correct Option: D
Explanation:

Vacuoles are the membrane-bound storage bubbles found in cells. They are large and centrally located in plant cell whereas in animal cells either they are too small or absent .They can store food materials, waste products, water etc.
