18. A plant is grown in bright sunshine.
After a few hours, a leaf is stained with iodine solution.
The diagram shows what is seen when the leaf is
placed under a microscope.
Which structure will be stained blue/black?

yes? sounds right, but you didn’t ask a question.

passive transport is a movement of biochemicals and other atomic or molecular substances across cell membranes without need of energy input. unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy.

so, according to what that says, i believe it's hypertonic and hypotonic.

good luck!

occluded front i think
