Effect of different colors of light on the rate of photosynthesis.

Given the above understanding, it is therefore important that the right environment factors are in existence for some chemical reactions to take place.

They do this by a process called Photosynthesis.

How does light intensity and duration affect the rate of photosynthesis?

Effects of different colors of light on the photosynthesis rate.

6CO + 6H O ® C H O + 12O (in the presence of light energy and chlorophyll) Aim- The aim of the experiment is to determine what effect light intensity has upon the rate of photosynthesis of Canadian Pondweed (Elodea)....

Photosynthesis is the procedure all plants go through to make food.

This desire to discover new ways of producing clean energy has lead scientists at Stanford University and other universities to discover a way to harness the electricity produced during the process of photosynthesis.

Effects of high temperature on photosynthesis and …

During the process of photosynthesis, carbon dioxide plus water in the presence of sunlight, enzymes and chlorophyll produce glucose and oxygen as waste product.

Photosynthesis in the wider sense, and its behaviour in relation to environment, is considered in this collection of reviews addressing currently important scientific topics. Photosynthesis is central to the performance of autotrophic plants, not in isolation or uniquely but combined with the processes determining growth and development as part of the whole organism's function and reproductive performance and survival. Ultimately reproduction and survival of the species depend on the efficiency of the different components of the whole organism (). All this is achieved by integration of many, complex, individually and finely regulated sub-processes, currently summarized with the now-familiar litany of genomics, proteomics and metabolomics (), plus the less familiar but arguably (because of its integrative role) more important physionomics (). Performance and efficiency of all sub-systems and of their integration in the system – the whole organism – are tested in evolutionary competition (). This may involve development of – and changes to – fundamental molecular mechanisms such as association of existing regulatory mechanisms, e.g. of transcription factors, producing altered characteristics in plant development and flower formation (). Biological success requires effective regulatory mechanisms in all processes, at all levels of organization. The plant kingdom is enormously diverse and widely distributed () and plants have achieved world dominance by ‘doing their thing’ effectively within particular environments (). However, environments are not constant anywhere; conditions fluctuate rapidly around a long-term mean, and there are extremes, i.e. conditions that occur infrequently as defined statistically. Of course, ‘extreme’ is a relative term: it can only be understood in relation to the ability of the species (actually its sub-systems and their integration into the whole organism) to survive and to perform adequately within a particular environment over a long period in the face of competition (). In addition, plants must cope with long-term changes in the mean and range (including extremes) of conditions. Ultimately, it is the ability of individuals of a species to adapt to extremes that determines distribution of the species. Limited adaptation may decrease the frequency of occurrence of a species and its contribution to the community and total biomass. Inability to adapt results in total elimination of the species from the area where those conditions occur, or if they occurred for a limited period, the species is absent for a span of time determined by the rate of recolonization and the frequency of the extreme conditions and competitive ability ().

How does photosynthesis affect our lives

Obtaining the holy grail of large agricultural production in dry and/or saline environments to which desired species are currently poorly adapted () will certainly require improvements in knowledge, both in genomics and breeding (; ) and in details of processes deep in metabolism ().These must be linked to detailed understanding of the environment. Assessing the potential for crop improvement realistically also depends on such understanding. How do plants adapt to their environment and what parts of the plant – genome to physionome – are susceptible? What is the weakest link? Given the number of species (and, in crops, cultivars or varieties) and the number of sub-processes (qualitative) and their ranges (quantitative), and the types (qualitative) and ranges (quantitative) of both abiotic and biotic environment factors, there is an enormous multi-dimensional matrix of possibilities. Even if for scientific study there is strong selection of species, conditions, etc, in order to try and identify mechanisms, it still leaves considerable room for uncertainty. Identifying mechanisms has progressed dramatically with the millions of person-hours and other resources invested over a considerable span of human endeavour: information has been increasing exponentially over recent decades. This explosion of information complicates the analysis of plants. Attempting to turn conceptual (qualitative) models into quantitative models is slow and fraught with uncertainty. Knowledge is the key, but are we in a position to use current knowledge sensibly? Can we avoid a science-fiction world of hopes and dreams ill-founded in reality, or pessimism that all is too complex and progress is not possible? One way of trying to do so is to review the scientific knowledge and progress and to chip away at the edifice (or fill in the matrix) with the aim of understanding plants in relation to their environments. Hence the group of reviews presented here.
