Measurement of Photosynthesis
sanaThe rate of photosynthesis is measured by one of the following methods: By measuring (I) the volume of CO, consumed (2) volume of oxygen liberated (3) amount of carbohydrate accumulated.…
Products of Photosynthesis
The products of photosynthesis are the carbohydrates and oxygen. Four carbohydrates, D-glucose. D-fructose, sucrose and starch are commonly are formed in the green cells during photosynthesis. Plant physiologists and biochemists…
ENDOPLASMIC RETICULUM
rubabThe word endoplasmic means "within- the cytoplasm. The word reticultun in ans "network.- The. ER consists of a network of membranous ubules and sacs called cisternae. The ER are extensive…
Factors affecting photosynthesis rate in a plant
Many external and internal factors affect the rate of photosynthesis. The external or environmental factors at:A light intensity, carbon dioxide concentration and temperature. The internal factor influencing the photosynthesis is…
THE CONCEPT OF LIMITING FACTORS
Sach 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…
ULTRASTRUCTURE OF PLANT CELL
All plants are made up of cells. The cell plays a fundamental role in the understanding of botany. It also helps in the understanding of chemistry. Cell is the simplest…
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…
