Cell Structure and Transport Review

Imagine you're a tiny human living inside a cell. How would you keep your home (the cell) in balance?

• Control what comes in and goes out of your home

• Be flexible

• Create a protective barrier around your home

• Provide structure and support to your home

Imagine you're a tiny scientist, and you've just shrunk yourself down to explore the inside of a cell. You notice that the cell is filled with a 10% salt solution, and you're floating in distilled water with 0% starch concentration. You know that water can travel across a semipermeable membrane, but starch cannot. What do you think you'll observe after an hour of your microscopic adventure?

• You think, 'The solution inside the cell is hypotonic and it's going to move into the cell.'

• You hypothesize, 'The solution inside the cell is hypertonic, so the water is going to move into the cell.'

• You predict, 'The solution inside the cell is hypotonic and it's going to move out of the cell.'

• You consider, 'The solution inside the cell is isotonic, so the water isn't going to move.'

Imagine you're a tiny creature living inside a cell. Which cell would be the most comfortable for you to maintain a balanced environment?

• The smallest cell, because it would be like living in a tiny, efficient apartment where it's easy to manage everything.

• The largest cell, because it would be like living in a huge mansion with lots of food storage but might be hard to manage.

• The largest cell, because it would be like living in a spacious loft with lots of room to grow.

• The medium cell, because it would be like living in a cozy house that's not too big or too small, making it efficient to manage.
