Urban Forestry & Urban Greening, 5 (4): 195–201.. Efforts at mitigating global biodiversity loss have often focused on preserving large, intact natural habitats. However, preserving biodiversity should also be an important goal in the urban environment, especially in highly urbanized areas where little natural habitat remains. Increasingly, research at the city/county scale as well as at the landscape scale reveals that urban areas can contain relatively high levels of biodiversity (. Posidonia oceanica. photosynthesis.

(Andy, Alex, Colin, Jordyn). Summary of Findings . In this lab, the effects of plant photosynthesis were investigated by comparing the rates of photosynthesis of two plants, spinach and kale. The rate of photosynthesis was measured the number of leaf cutouts on the surface per minute. These floating leaf cutouts show that oxygen, a product of photosynthesis is produced. We found that the rate of photosynthesis for the spinach leaves was 8.6 cutouts per minutes, 1.4 less than that of the kale leaves (10 cutouts per minute.) This difference could be a result the different amounts of light absorbing chlorophyll present in each leaf, or a difference in vascular tissue sizes, which may affect the plant’s ability to absorb water for photosynthesis..
