What are the inputs of cellular respiration
Oxygen and nutrients
What do cells obtain from respiration?
energy
Where in a cell does respiration occur?
Mitochondria
What waste is produced during respiration?
Carbon Dioxide (CO2)
What evidence did you observe from our respiration activity?
The balloon inflated and there were bubbles in the tube.
What is the function of the cell membrane
To let things that won’t hurt the cell in and keep everything else out.
What substance was able to pass through the membrane? How do you know?
The Iodine was able to pass through. We knew because the starch in both experiments turned purple.
What substance was not able to pass through the membrane? How do you know?
The starch was not able to pass through. We knew because the starch in both experiments turned purple.
Were the carbon pieces or powder more efficient at absorbing the blue dye?
The powder was more efficient because it had more surface area that the pieces.
Why are small cells more efficient than large cells at absorbing oxygen and nutrients
more surface area.
What are some of the common structures in a cell
nucleus and cell membrane
Why is the nucleus an important part of most cells?
It has the information to drive a cell.
