THE CONCEPT OF LIMITING FACTORS
sanaSach developed three cardinal points for each factor affecting thephotosynthesis. These cardinals have minimum, optimum and maximum values. Minimum: It is the minimum value of a factor at which photosynthesis…
Crassulacean Acid metabolism (CAM)
Crassulacean metabolism occurs in succulents plants. The CAM plants are without well developed palisade cells. They contain mostly spongy mesophyll. Bundle sheath cells are present. But they are similar to…
PHOTOSYNTHESIS IN C. PLANTS
The initial product of carbon dioxide fixation in some of the tropical and subtropical plants is malic acid or malate. Malate is 4-C compound. Therefore these plants are called C-4…
DARK REACTION OR CALVIN – BENSON CYCLE OR C3 CYCLE
The series of reactions in which carbon is fixed in the synthesis of sugar is called Calvin — Benson cycle. It takes place in the stroma of chloroplast. Discovery of…
LIGHT REACTION OR PHOTOCHEMICAL PHASE (photophosphorylation) OR HILL’S REACTION
The process in which NADPH, and ATP are formed in the presences o light is called light reaction or photochemical phase of photosynthesis. I was studied by Robert Hill. So…
MECHANISM OF PHOTOSYNTHESIS LIGHT DEPENDENT OR LIGHT REACTION
PHOTO-SYSTEMS Photosynthetic pigments are organized into clusters called photo-systems. These photo-systems absorb and utilize the solar energy efficiently in the thylakoid membranes. Each photo-system is composed of two parts. I.…
Absorption VS Action spectra
Light is electromagnetic energy. Electrochemical energy travels in the form of waves. The distance between the crest of the electromagnetic waves is called wavelength. The entire range of radiations is…
PROCESS OF PHOTOSYNTHESIS
Photosynthesis (photo-light, synthesis-putting together) may be defined as the process in whieh the green plants synthesize carbohydrates from carbon dioxide and water, using the energy of sunlight. 673 K cal…
