Also‚ if the concentration of NaHCO3 increased or decreased‚ it would affect the rate of photosynthesis‚ as all plants requires carbon dioxide in one form or another to

light was less intense the O2 bubble production will be lower. Basically the plant that is closer to the light will produce more bubbles than the plant that is placed farther away from the light source. In this lab the independent variable is the light intensity (distance from light source) and the dependent variable is oxygen output (number of bubbles). Since the distance was changed in the lab the control was the plant placed 0.0m away from the light source. After‚ evenly cutting 10 evergreen sprigs

Although deliberately shortening plants was initially done for practical purposes‚ this craft also began to be seen as

Abstract Stomata is important to plants because of their role in gas exchange and photosynthesis. Clear nail polish and clear plastic tape were used to make leaf impressions of A. floridanum. Once impressions were completed‚ compound microscopes were used to count the total number of stomata per slide. The counts of stomata were used to find stomatal densities‚ along with the open/closed ratios of stomata. Stomatal density and open/close ratio of stomata did not differ between the two locations
