Introduction It seems that in our day and age humans rely on caffeine for many things from that morning cup of coffee‚ soda with popcorn‚ caffeine infused skin products and many other applications. Our premises are that if caffeine can help with our skin and energy boost then wouldn’t the same apply to plants? The goal of this biology project is to examine the effect of caffeine on plant growth. Caffeine comes from a plant so it would seem that it could help plant growth. A plausible prediction

most weight gain (g) because the solution is hypotonic – a hypotonic solution results in the water diffusing into the cell because the molecules of the substance are moving from an area of higher concentration (outside of the cell) to an area of lower concentration (inside the cell) (Hammel & Schelegel 2005). Therefore‚ the water was moving into the cell‚ causing the potato cell to increase in size. The potato appeared to be quite turgid and swollen through observation. The 3% salt solution resulted

Measuring the rate of cellular respiration in yeast within different types of sugar Aim/Reasearch Question: How can the rate of cellular respiration be measured to find out if sucrose‚ dextrose‚ lactose‚ or maltose lets the yeast to respire more than others. Hypothesis: I think‚ dextrose yeast solution will respire the most number of bubbles because it is the simplest sugar to break.
