Looking at data to make conclusions about membrane transport

What is a controlled variable in the investigation?

A. amount that cell grows

B. type of cell

C. initial surface area of cell

D. life span of cell

A. amount that cell grows

B. type of cell

C. initial surface area of cell

D. lifespand of cell

A. the amount of expansion of the cell dependes on the type of cel

B. the size of the cells never changes

C. cell type and amount of expansion by osmosis are not related

D. animal cells expand more than plant cells when they are put in pure water

E. plant and animal cells expand the same amount when put in pure water

A. cells absorb water to expand so as more water is added, the cells expand more

B. plant and animal cells have the same organelles, so they both expand the same amount

C. plants cells have cell wall that limit the amount they expand and animal cells do not

D. animal cells are more active than plant cells, so they expand more

A. There was a higher concentration of water inside the tubing and the water exited the tubing

B. There was a higher concentration of water outside the tubing and the water entered the tubing

C. There was a higher concentration of sucrose outside the tubing and the water exited the tubing

A. the greater the sucrose concentration in the bad then the greater the % change

B. molecules only move when the sucrose concentration is above 5.00%

C. the change in mass indicates the movement of sucrose molecules

D. the distilled water in the beakers had the least change in mass

C. cell type and amount of expansion by osmosis are not related

D. animal cells expand more than plant cells when they are put in pure water

E. plant and animal cells expand the same amount when put in pure water
