GENERAL KNOWLEDGE

Detailed explanation-1: -Scientists discovered that a distinct organelle, the vacuole, plays a critical role in regulating the delivery of CO2 to the photosynthesis-conducting chloroplasts. Plant vacuoles are fluid-filled organelles bound by a single membrane called the tonoplast, and contain a wide range of inorganic ions and molecules.

Detailed explanation-2: -A tonoplast is actually the membrane that surrounds the large vacuole in a mature plant cell. We get the name ‘tonoplast’ from Greek, which translated looks something like ‘tone, tension, stretching, and molded. ‘ This would coincide well with where the tonoplast exists. It is also known as the ‘vacuolar membrane.

Detailed explanation-3: -The single layered membrane of vacuoles is known as tonoplast.

Detailed explanation-4: -Membrane-bound organelles are cellular structures that are bound by a biological membrane. The membrane may be a single layer or a double layer of lipids and typically with interspersed proteins.
