Explanation / Answer

Answer:

26. (a) expands

Explanation:

The cell has 75% water and 25% salt. It is surrounded by a solution with 20% sat and 80% water. So, the cell is in a hypotonic solution. Water will move inside the cell through osmosis, as a result the cell will swell up.

27. (a) monera

Explanation:

Kingdom Monera consists of simple, unicellular prokaryotic cells without nucleus.

28. (a) cilia

Explanation:

Microtubules are organized by MTOCs and are found in cilia, flagella and spindle.

29. (a) Shrinks

Explanation:

In hypertonic solution, the water moves from inside of the cell to the solution and the cell shrinks.
