For number 1 the first arrow is the cell wall, the second is the membrane, and the last arrow would be the cytoplasm
For number 2 they are in distilled water Bc they are remaining the same and not shrinking up
For three draw the cells smaller salt water sucks the water out of them
For four they get smaller because the salt has a higher concentration making the water leave the cell. Once water has left the cell begins to shrink
