what is tonoplast ?.?
Answers
The membrane surrounding the vacuole is known as tonoplast. Tonoplast is a single membrane which separates the cytoplasm from the vacuoles. Tonoplasts facilitate the uphill transport of many ions and other materials in plant , allowing their vacuole concentration higher than cytoplasm.
Whoa what is it?
So cute.
Answer:
a membrane which bounds the chief vacuole of a plant cell.
Explanation:
Tonoplast is a single membrane that bounds the vacuoles and separates it from cytoplasm. In plants, tonoplasts facilitate uphill transport of many ions and other materials, making their concentration higher in vacuole than cytoplasm.
The tonoplast is the central vacuole's membrane; it is also known as the vacuolar membrane. It separates the contents of the central vacuole from the rest of the cell. It is made up of phospholipids and proteins, just like the cell membrane that covers the plant cell.
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.
