      photosynthesis can occur in a sunken leaf. As photosynthesis proceeds, oxygen accumulates in the air spaces of the spongy mesophyll, and the leaf disk will once again become buoyant and rise in a column of water. Therefore, the rate of photosynthesis can be indirectly measured by the rate of rise of the leaf disks. The Floating Disk Technique

      A number of factors are known to affect photosynthesis rates in plants. Classically, the variation of factors is as shown in Figure 1 (Hall and Rao, 1999). The interpretation (Hall and Rao, 1999) of the plots can be summarised as: l at low light intensities, the rate …

      students and teachers will discuss their findings in relation to macro-level factors that affect ecosystem health and climate change. Objectives: Students will gain a better understanding of the biochemical process of photosynthesis as well as the ecological factors that affect and are affected by photosynthesis processes.

      increase of o-02-o-04 unit as a result of 2 hr. photosynthesis, during which the rate increased fourfold. If the apparent assimilatory quotient is known, the change in pH consequent upon a period of photosynthesis can be calculated from the amount of oxygen evolved and the value obtained compared with the observed value. The quotient


    • Rate of photosynthesis: limiting factors

      Limiting factors The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature. In any given situation any one of these may become a limiting factor, in other words the factors that directly affects the rate at which photosynthesis can take place masking the effects of the other factors.

      PHOTOSYNTHESIS What factors affect the rate of photosynthesis in living leaves? BACKGROUND Photosynthesis fuels ecosystems and replenishes the Earth’s atmosphere with oxygen. Like all enzyme-driven reactions, the rate of photosynthesis can be measured by either the disappearance of substrate or the accumulation of product (or by-products).

      Photosynthesis in Ponds Plants in water need to photosynthesise just like those on land. Rates of photosynthesis can be slower in water, however, as the levels carbon dioxide dissolved in the water can be variable. This traditional experiment on the rates of photosynthsesis in aquatic plants compares three common species.
