Photosynthetic Apparatus - The photosynthetic pigments chlorophylls are present in the leaves because of which the leaves are green in colour and are called the photosynthetic organs. The leaves have the following structure: Histological Details of a Leaf in Cross Sect..

Photosynthetic Pigments - Molecules of chlorophyll-a, chlorophyll-b, carotene and xanthopyhll are situated in the thylakoid membranes. For light energy to be used by living systems, it must first be absorbed. A pigment is any substance that absorbs light. Chlorophyll, the pigment that mak..

The kingdom Metaphyta (or the plant kingdom in its true sense) includes all the eukaryotic, multicellular, photosynthetic plants found in this biosphere. It consists of three major groups of plants algae, bryophytes and tracheophyte..

The rate of transpiration is affected by many factors such as light, temperature, availability of soil water and atmospheric humidity. The plants also show adaptations to reduce transpiration and thereby reduce water loss. For example: Desert plants may not have leaves (stem has..

Although matter circulates, energy cannot be reused indefinitely. Solar energy is converted by the photosynthetic producers (plants) into chemical energy in the form of plant carbohydrates. Herbivores consume the plant carbohydrates and so this chemical..

Significance of Photosynthesis - Photosynthesis is the only process which produces enormous quantities of organic matter for sustaining the life on this globe. It is the only known method of manufacture of organic food from inorganic raw materials. Animals including man are directly or indirectly d..

In C 3 plants, the rate of photosynthesis increases with an increase. In CO 2 concentration upto 500 m l.l - 1 . In C 4 plants, photosynthetic rate increases with an increase in CO 2 concentration. However these plants attain saturation at around 360 ..

Compensation Point - At a given low concentration of CO 2 and non-limiting light intensity, the photosynthetic rate of a given plant will be equal to the total amount of respiration. The atmospheric concentration of CO 2 at which photosynthesis just compensates for respiration i..
