佢應該係non-living cell..但是..請問液泡有selectively permeable?

Vacuole is surrounded by a membrane...I think it is selectively permeable[]
However,I think you should not call it a non-living cell as vacuole is already a part of a cell[]

selectively permeable should be the plasma membrane.

The function of the vacuole is to set up a pressure againist the cytoplasm and the cell wall of the plant cell.

Vacuole is a large cavity filled with the cell sap
I think it is not a living cell

I agree with #6

it is not necessary to decide whether it is living cell or not
as it is a part of a cell

Vacuole has a single membrane called tonoplast which is semipermeable.
All cellular membranes are semipermeable.
All organelles known in CE are membrane-bounded.
Vacuole is living.
