Egg membranes from three eggs were carefully taken out and labeled as a, b , c. Each of these membranes were filled with 1% solution of sugar. Membrane A was immersed in 0.5% sugar solution, Membrane B was immersed in 1% sugar solution and Membrane c was immersed in 2% sugar solution. Predict the behavior of the three membranes?

The correct answer would be -

Membrane A - Hypotonic solution - the movement of water towards inside the cell

Membrane B - Isotonic soltion - there will be no movement of water

Membrane C - Hyertonic solution - the movement of water towards outside of the cell

Explanation:

This experiment deals with tonicity as this solution will affect the tonicity of the egg membrane. In membrane A there are more solutes inside the cell than outside the cell so it is hypotonic solution so the movement of water will be towards inside the cell.

In membrane B the solutes are equal in both sides so there will be no movement as its isotonic condition while in membrane C the solution is in hypertonic situation as the solutes are more outside than inside.

Thus, the behavior of the membranes are-

Membrane A - Hypotonic solution - the movement of water towards inside the cell

Membrane B - Isotonic soltion - there will be no movement of water

Membrane C - Hyertonic solution - the movement of water towards outside of the cell

some fungi obtain their nutrients from a living host (plant or animal) and are called most biotrophic fungi have fairly narrow host ranges—they are specialized on a limited called rhizomorphs that allow the fungus to grow from one tree to another. ascospores are formed inside a sac-like structure called an ascus. so your answer is a
